+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+
+## 关于 Camoufox
+
+本项目使用 [Camoufox](https://camoufox.com/) 来提供具有增强反指纹检测能力的浏览器实例。
+
+- **核心目标**: 模拟真实用户流量，避免被网站识别为自动化脚本或机器人
+- **实现方式**: Camoufox 基于 Firefox，通过修改浏览器底层 C++ 实现来伪装设备指纹（如屏幕、操作系统、WebGL、字体等），而不是通过容易被检测到的 JavaScript 注入
+- **Playwright 兼容**: Camoufox 提供了与 Playwright 兼容的接口
+- **Python 接口**: Camoufox 提供了 Python 包，可以通过 `camoufox.server.launch_server()` 启动其服务，并通过 WebSocket 连接进行控制
+
+使用 Camoufox 的主要目的是提高与 AI Studio 网页交互时的隐蔽性，减少被检测或限制的可能性。但请注意，没有任何反指纹技术是绝对完美的。
+
+## 重要提示
+
+### 三层响应获取机制与参数控制
+
+- **响应获取优先级**: 项目采用三层响应获取机制，确保高可用性：
+
+  1. **集成流式代理服务 (Stream Proxy)**: 默认启用，端口 3120，提供最佳性能和稳定性
+  2. **外部 Helper 服务**: 可选配置，需要有���认证文件，作为备用方案
+  3. **Playwright 页面交互**: 最终后备方案，通过浏览器自动化获取响应
+
+- **参数控制机制**:
+
+  - **流式代理模式**: 支持基础参数传递，性能最优
+  - **Helper 服务模式**: 参数支持取决于外部服务实现
+  - **Playwright 模式**: 完整支持所有参数（`temperature`, `max_output_tokens`, `top_p`, `stop`, `reasoning_effort`等）
+
+- **脚本注入增强**: v3.0 版本使用 Playwright 原生网络拦截，确保注入模型与原生模型 100%一致
+
+### 客户端管理历史
+
+**客户端管理历史，代理不支持 UI 内编辑**: 客户端负责维护完整的聊天记录并将其发送给代理。代理服务器本身不支持在 AI Studio 界面中对历史消息进行编辑或分叉操作。
+
+## 未来计划
+
+以下是一些计划中的改进方向：
+
+- **云服务器部署指南**: 提供更详细的在主流云平台上部署和管理服务的指南
+- **认证更新流程优化**: 探索更便捷的认证文件更新机制，减少手动操作
+- **流程健壮性优化**: 减少错误几率和接近原生体验

+# AI Studio Proxy Server (Javascript Version - DEPRECATED)
+
+**⚠️ 警告：此 Javascript 版本 (`server.cjs`, `auto_connect_aistudio.cjs`) 已被弃用且不再维护。推荐使用项目根目录下的 Python 版本，该版本采用了模块化架构设计，具有更好的稳定性和可维护性。**
+
+**📖 查看最新文档**: 请参考项目根目录下的 [`README.md`](../README.md) 了解当前Python版本的完整使用说明。
+
+---
+
+[点击查看项目使用演示视频](https://drive.google.com/file/d/1efR-cNG2CNboNpogHA1ASzmx45wO579p/view?usp=drive_link)
+
+这是一个 Node.js + Playwright 服务器，通过模拟 OpenAI API 的方式来访问 Google AI Studio 网页版，服务器无缝交互转发 Gemini 对话。这使得兼容 OpenAI API 的客户端（如 Open WebUI, NextChat 等）可以使用 AI Studio 的无限额度及能力。
+
+## ✨ 特性 (Javascript 版本)
+
+*   **OpenAI API 兼容**: 提供 `/v1/chat/completions` 和 `/v1/models` 端点，兼容大多数 OpenAI 客户端。
+*   **流式响应**: 支持 `stream=true`，实现打字机效果。
+*   **非流式响应**: 支持 `stream=false`，一次性返回完整 JSON 响应。
+*   **系统提示词 (System Prompt)**: 支持通过请求体中的 `messages` 数组的 `system` 角色或额外的 `system_prompt` 字段传递系统提示词。
+*   **内部 Prompt 优化**: 自动包装用户输入，指导 AI Studio 输出特定格式（流式为 Markdown 代码块，非流式为 JSON），并包含起始标记 `<<<START_RESPONSE>>>` 以便解析。
+*   **自动连接脚本 (`auto_connect_aistudio.cjs`)**:
+    *   自动查找并启动 Chrome/Chromium 浏览器，开启调试端口，**并设置特定窗口宽度 (460px)** 以优化布局，确保"清空聊天"按钮可见。
+    *   自动检测并尝试连接已存在的 Chrome 调试实例。
+    *   提供交互式选项，允许用户选择连接现有实例或自动结束冲突进程。
+    *   自动查找或打开 AI Studio 的 `New chat` 页面。
+    *   自动启动 `server.cjs`。
+*   **服务端 (`server.cjs`)**:
+    *   连接到由 `auto_connect_aistudio.cjs` 管理的 Chrome 实例。
+    *   **自动清空上下文**: 当检测到来自客户端的请求可能是"新对话"时（基于消息历史长度），自动模拟点击 AI Studio 页面上的"Clear chat"按钮及其确认对话框，并验证清空效果，以实现更好的会话隔离。
+    *   处理 API 请求，通过 Playwright 操作 AI Studio 页面。
+    *   解析 AI Studio 的响应，提取有效内容。
+    *   提供简单的 Web UI (`/`) 进行基本测试。
+    *   提供健康检查端点 (`/health`)。
+*   **错误快照**: 在 Playwright 操作、响应解析或**清空聊天**出错时，自动在项目根目录下的 `errors/` 目录下保存页面截图和 HTML，方便调试。(注意: Python 版本错误快照在 `errors_py/`)
+*   **依赖检测**: 两个脚本在启动时都会检查所需依赖，并提供安装指导。
+*   **跨平台设计**: 旨在支持 macOS, Linux 和 Windows (WSL 推荐)。
+
+## ⚠️ 重要提示 (Javascript 版本)
+
+*   **非官方项目**: 本项目与 Google 无关，依赖于对 AI Studio Web 界面的自动化操作，可能因 AI Studio 页面更新而失效。
+*   **自动清空功能的脆弱性**: 自动清空上下文的功能依赖于精确的 UI 元素选择器 (`CLEAR_CHAT_BUTTON_SELECTOR`, `CLEAR_CHAT_CONFIRM_BUTTON_SELECTOR` 在 `server.cjs` 中)。如果 AI Studio 页面结构发生变化，此功能可能会失效。届时需要更新这些选择器。
+*   **不支持历史编辑/分叉**: 即使实现了新对话的上下文清空，本代理仍然无法支持客户端进行历史消息编辑并从该点重新生成对话的功能。AI Studio 内部维护的对话历史是线性的。
+*   **固定窗口宽度**: `auto_connect_aistudio.cjs` 会以固定的宽度 (460px) 启动 Chrome 窗口，以确保清空按钮可见。
+*   **安全性**: 启动 Chrome 时开启了远程调试端口 (默认为 `8848`)，请确保此端口仅在受信任的网络环境中使用，或通过防火墙规则限制访问。切勿将此端口暴露到公网。
+*   **稳定性**: 由于依赖浏览器自动化，其稳定性不如官方 API。长时间运行或频繁请求可能导致页面无响应或连接中断，可能需要重启浏览器或服务器。
+*   **AI Studio 限制**: AI Studio 本身可能有请求频率限制、内容策略限制等，代理服务器无法绕过这些限制。
+*   **参数配置**: **像模型选择、温度、输出长度等参数，需要您直接在 AI Studio 页面的右侧设置面板中进行调整。本代理服务器目前不处理或转发这些通过 API 请求传递的参数。** 您需要预先在 AI Studio Web UI 中设置好所需的模型和参数。
+
+## 🛠️ 配置 (Javascript 版本)
+
+虽然不建议频繁修改，但了解以下常量可能有助于理解脚本行为或在特殊情况下进行调整：
+
+**`auto_connect_aistudio.cjs`:**
+
+*   `DEBUGGING_PORT`: (默认 `8848`) Chrome 浏览器启动时使用的远程调试端口。
+*   `TARGET_URL`: (默认 `'https://aistudio.google.com/prompts/new_chat'`) 脚本尝试打开或导航到的 AI Studio 页面。
+*   `SERVER_SCRIPT_FILENAME`: (默认 `'server.cjs'`) 由此脚本自动启动的 API 服务器文件名。
+*   `CONNECT_TIMEOUT_MS`: (默认 `20000`) 连接到 Chrome 调试端口的超时时间 (毫秒)。
+*   `NAVIGATION_TIMEOUT_MS`: (默认 `35000`) Playwright 等待页面导航完成的超时时间 (毫秒)。
+*   `--window-size=460,...`: 启动 Chrome 时传递的参数，固定宽度以保证 UI 元素（如清空按钮）位置相对稳定。
+
+**`server.cjs`:**
+
+*   `SERVER_PORT`: (默认 `2048`) API 服务器监听的端口。
+*   `AI_STUDIO_URL_PATTERN`: (默认 `'aistudio.google.com/'`) 用于识别 AI Studio 页面的 URL 片段。
+*   `RESPONSE_COMPLETION_TIMEOUT`: (默认 `300000`) 等待 AI Studio 响应完成的总超时时间 (毫秒，5分钟)。
+*   `POLLING_INTERVAL`: (默认 `300`) 轮询检查 AI Studio 页面状态的间隔 (毫秒)。
+*   `SILENCE_TIMEOUT_MS`: (默认 `3000`) 判断 AI Studio 是否停止输出的静默超时时间 (毫秒)。
+*   `CLEAR_CHAT_VERIFY_TIMEOUT_MS`: (默认 `5000`) 等待并验证清空聊天操作完成的超时时间 (毫秒)。
+*   **CSS 选择器**: (`INPUT_SELECTOR`, `SUBMIT_BUTTON_SELECTOR`, `RESPONSE_CONTAINER_SELECTOR`, `LOADING_SPINNER_SELECTOR`, `ERROR_TOAST_SELECTOR`, `CLEAR_CHAT_BUTTON_SELECTOR`, `CLEAR_CHAT_CONFIRM_BUTTON_SELECTOR`) 这些常量定义了脚本用于查找页面元素的选择器。**修改这些值需要具备前端知识，并且如果 AI Studio 页面更新，这些是最可能需要调整的部分。**
+
+## ⚙️ Prompt 内部处理 (Javascript 版本)
+
+为了让代理能够解析 AI Studio 的输出，`server.cjs` 会在将你的 Prompt 发送到 AI Studio 前进行包装，加入特定的指令，要求 AI：
+
+1.  **对于非流式请求 (`stream=false`)**: 将整个回复包裹在一个 JSON 对象中，格式为 `{"response": "<<<START_RESPONSE>>>[AI的实际回复]"}`。
+2.  **对于流式请求 (`stream=true`)**: 将整个回复（包括开始和结束）包裹在一个 Markdown 代码块 (```) 中，并在实际回复前加上标记 `<<<START_RESPONSE>>>`，形如：
+    ```markdown
+    ```
+    <<<START_RESPONSE>>>[AI的实际回复第一部分]
+    [AI的实际回复第二部分]
+    ...
+    ```
+    ```
+
+`server.cjs` 会查找 `<<<START_RESPONSE>>>` 标记来提取真正的回复内容。这意味着你通过 API 得到的回复是经过这个内部处理流程的，AI Studio 页面的原始输出格式会被改变。
+
+## 🚀 开始使用 (Javascript 版本)
+
+### 1. 先决条件
+
+*   **Node.js**: v16 或更高版本。
+*   **NPM / Yarn / PNPM**: 用于安装依赖。
+*   **Google Chrome / Chromium**: 需要安装浏览器本体。
+*   **Google AI Studio 账号**: 并能正常访问和使用。
+
+### 2. 安装
+
+1.  **进入弃用版本目录**:
+    ```bash
+    cd deprecated_javascript_version
+    ```
+
+2.  **安装依赖**:
+    根据 `package.json` 文件，脚本运行需要以下核心依赖：
+    *   `express`: Web 框架，用于构建 API 服务器。
+    *   `cors`: 处理跨域资源共享。
+    *   `playwright`: 浏览器自动化库。
+    *   `@playwright/test`: Playwright 的测试库，`server.cjs` 使用其 `expect` 功能进行断言。
+
+    使用你的包管理器安装：
+    ```bash
+    npm install
+    # 或
+    yarn install
+    # 或
+    pnpm install
+    ```
+
+### 3. 运行
+
+只需要运行 `auto_connect_aistudio.cjs` 脚本即可启动所有服务：
+
+```bash
+node auto_connect_aistudio.cjs
+```
+
+这个脚本会执行以下操作：
+
+1.  **检查依赖**: 确认上述 Node.js 模块已安装，且 `server.cjs` 文件存在。
+2.  **检查 Chrome 调试端口 (`8848`)**:
+    *   如果端口空闲，尝试自动查找并启动一个新的 Chrome 实例（窗口宽度固定为 460px），并打开远程调试端口。
+    *   如果端口被占用，询问用户是连接现有实例还是尝试清理端口后启动新实例。
+3.  **连接 Playwright**: 尝试连接到 Chrome 的调试端口 (`http://127.0.0.1:8848`)。
+4.  **管理 AI Studio 页面**: 查找或打开 AI Studio 的 `New chat` 页面 (`https://aistudio.google.com/prompts/new_chat`)，并尝试置于前台。
+5.  **启动 API 服务器**: 如果以上步骤成功，脚本会自动在后台启动 `node server.cjs`。
+
+当 `server.cjs` 成功启动并连接到 Playwright 后，您将在终端看到类似以下的输出（来自 `server.cjs`）：
+
+```
+=============================================================
+          🚀 AI Studio Proxy Server (vX.XX - Queue & Auto Clear) 🚀
+=============================================================
+🔗 监听地址: http://localhost:2048
+   - Web UI (测试): http://localhost:2048/
+   - API 端点:   http://localhost:2048/v1/chat/completions
+   - 模型接口:   http://localhost:2048/v1/models
+   - 健康检查:   http://localhost:2048/health
+-------------------------------------------------------------
+✅ Playwright 连接成功，服务已准备就绪！
+-------------------------------------------------------------
+```
+*(版本号可能不同)*
+
+此时，代理服务已准备就绪，监听在 `http://localhost:2048`。
+
+### 4. 配置客户端 (以 Open WebUI 为例)
+
+1.  打开 Open WebUI。
+2.  进入 "设置" -> "连接"。
+3.  在 "模型" 部分，点击 "添加模型"。
+4.  **模型名称**: 输入你想要的名字，例如 `aistudio-gemini-cjs`。
+5.  **API 基础 URL**: 输入代理服务器的地址，例如 `http://localhost:2048/v1` (注意包含 `/v1`)。
+6.  **API 密钥**: 留空或输入任意字符 (服务器不验证)。
+7.  保存设置。
+8.  现在，你应该可以在 Open WebUI 中选择 `aistudio-gemini-cjs` 模型并开始聊天了。
+
+### 5. 使用测试脚本 (可选)
+
+本目录下提供了一个 `test.js` 脚本，用于在命令行中直接与代理进行交互式聊天。
+
+1.  **安装额外依赖**: `test.js` 使用了 OpenAI 的官方 Node.js SDK。
+    ```bash
+    npm install openai
+    # 或 yarn add openai / pnpm add openai
+    ```
+2.  **检查配置**: 打开 `test.js`，确认 `LOCAL_PROXY_URL` 指向你的代理服务器地址 (`http://127.0.0.1:2048/v1/`)。`DUMMY_API_KEY` 可以保持不变。
+3.  **运行测试**: 在 `deprecated_javascript_version` 目录下运行：
+    ```bash
+    node test.js
+    ```
+    之后就可以在命令行输入问题进行测试了。输入 `exit` 退出。
+
+## 💻 多平台指南 (Javascript 版本)
+
+*   **macOS**:
+    *   `auto_connect_aistudio.cjs` 通常能自动找到 Chrome。
+    *   防火墙可能会提示是否允许 Node.js 接受网络连接，请允许。
+*   **Linux**:
+    *   确保已安装 `google-chrome-stable` 或 `chromium-browser`。
+    *   如果脚本找不到 Chrome，你可能需要修改 `auto_connect_aistudio.cjs` 中的 `getChromePath` 函数，手动指定路径，或者创建一个符号链接 (`/usr/bin/google-chrome`) 指向实际的 Chrome 可执行文件。
+    *   某些 Linux 发行版可能需要安装额外的 Playwright 依赖库，参考 [Playwright Linux 文档](https://playwright.dev/docs/intro#system-requirements)。运行 `npx playwright install-deps` 可能有助于安装。
+*   **Windows**:
+    *   **强烈建议使用 WSL (Windows Subsystem for Linux)**。在 WSL 中按照 Linux 指南操作通常更顺畅。
+    *   **直接在 Windows 上运行 (不推荐)**:
+        *   `auto_connect_aistudio.cjs` 可能需要手动修改 `getChromePath` 函数来指定 Chrome 的完整路径 (例如 `C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe`)。注意路径中的反斜杠需要转义 (`\\`)。
+        *   防火墙设置需要允许 Node.js 和 Chrome 监听和连接端口 (`8848` 和 `2048`)。
+        *   由于文件系统和权限差异，可能会遇到未知问题，例如端口检查或进程结束操作 (`taskkill`) 失败。
+
+## 🔧 故障排除 (Javascript 版本)
+
+*   **`auto_connect_aistudio.cjs` 启动失败或报错**:
+    *   **依赖未找到**: 确认运行了 `npm install` 等命令。
+    *   **Chrome 路径找不到**: 确认 Chrome/Chromium 已安装，并按需修改 `getChromePath` 函数或创建符号链接 (Linux)。
+    *   **端口 (`8848`) 被占用且无法自动清理**: 根据脚本提示，使用系统工具（如 `lsof -i :8848` / `tasklist | findstr "8848"`）手动查找并结束占用端口的进程。
+    *   **连接 Playwright 超时**: 确认 Chrome 是否已成功启动并监听 `8848` 端口，防火墙是否阻止本地连接 `127.0.0.1:8848`。查看 `auto_connect_aistudio.cjs` 中的 `CONNECT_TIMEOUT_MS` 是否足够。
+    *   **打开/导航 AI Studio 页面失败**: 检查网络连接，尝试手动在浏览器中打开 `https://aistudio.google.com/prompts/new_chat` 并完成登录。查看 `NAVIGATION_TIMEOUT_MS` 是否足够。
+    *   **窗口大小问题**: 如果 460px 宽度导致问题，可以尝试修改 `auto_connect_aistudio.cjs` 中的 `--window-size` 参数，但这可能影响自动清空功能。
+*   **`server.cjs` 启动时提示端口被占用 (`EADDRINUSE`)**:
+    *   检查是否有其他程序 (包括旧的服务器实例) 正在使用 `2048` 端口。关闭冲突程序或修改 `server.cjs` 中的 `SERVER_PORT`。
+*   **服务器日志显示 Playwright 未就绪或连接失败 (在 `server.cjs` 启动后)**:
+    *   通常意味着 `auto_connect_aistudio.cjs` 启动的 Chrome 实例意外关闭或无响应。检查 Chrome 窗口是否还在，AI Studio 页面是否崩溃。
+    *   尝试关闭所有相关进程（`node` 和 `chrome`），然后重新运行 `node auto_connect_aistudio.cjs`。
+    *   检查根目录下的 `errors/` 目录是否有截图和 HTML 文件，它们可能包含 AI Studio 页面的错误信息或状态。
+*   **客户端 (如 Open WebUI) 无法连接或请求失败**: 
+    *   确认 API 基础 URL 配置正确 (`http://localhost:2048/v1`)。
+    *   检查 `server.cjs` 运行的终端是否有错误输出。
+    *   确保客户端和服务器在同一网络中，且防火墙没有阻止从客户端到服务器 `2048` 端口的连接。
+*   **API 请求返回 5xx 错误**: 
+    *   **503 Service Unavailable / Playwright not ready**: `server.cjs` 无法连接到 Chrome。
+    *   **504 Gateway Timeout**: 请求处理时间超过了 `RESPONSE_COMPLETION_TIMEOUT`。可能是 AI Studio 响应慢或卡住了。
+    *   **502 Bad Gateway / AI Studio Error**: `server.cjs` 在 AI Studio 页面上检测到了错误提示 (`toast` 消息)，或无法正确解析 AI 的响应。检查 `errors/` 快照。
+    *   **500 Internal Server Error**: `server.cjs` 内部发生未捕获的错误。检查服务器日志和 `errors/` 快照。
+*   **AI 回复不完整、格式错误或包含 `<<<START_RESPONSE>>>` 标记**: 
+    *   AI Studio 的 Web UI 输出不稳定。服务器尽力解析，但可能失败。
+    *   非流式请求：如果返回的 JSON 中缺少 `response` 字段或无法解析，服务器可能返回空内容或原始 JSON 字符串。检查 `errors/` 快照确认 AI Studio 页面的实际输出。
+    *   流式请求：如果 AI 未按预期输出 Markdown 代码块或起始标记，流式传输可能提前中断或包含非预期内容。
+    *   尝试调整 Prompt 或稍后重试。
+*   **自动清空上下文失败**:
+    *   服务器日志出现 "清空聊天记录或验证时出错" 或 "验证超时" 的警告。
+    *   **原因**: AI Studio 网页更新导致 `server.cjs` 中的 `CLEAR_CHAT_BUTTON_SELECTOR` 或 `CLEAR_CHAT_CONFIRM_BUTTON_SELECTOR` 失效。
+    *   **解决**: 检查 `errors/` 快照，使用浏览器开发者工具检查实际页面元素，并更新 `server.cjs` 文件顶部的选择器常量。
+    *   **原因**: 清空操作本身耗时超过了 `CLEAR_CHAT_VERIFY_TIMEOUT_MS`。
+    *   **解决**: 如果网络或机器较慢，可以尝试在 `server.cjs` 中适当增加这个超时时间。

+本文档提供了使用 Docker 构建和运行 AI Studio Proxy API 项目的完整指南，包括 Poetry 依赖管理、`.env` 配置管理和脚本注入功能。
+
+## 🐳 概述
+
+Docker 部署提供了以下优势：
+- ✅ **环境隔离**: 容器化部署，避免环境冲突
+- ✅ **Poetry 依赖管理**: 使用现代化的 Python 依赖管理工具
+- ✅ **统一配置**: 基于 `.env` 文件的配置管理
+- ✅ **版本更新无忧**: `bash update.sh` 即可完成更新
+- ✅ **跨平台支持**: 支持 x86_64 和 ARM64 架构
+- ✅ **配置持久化**: 认证文件和日志持久化存储
+- ✅ **多阶段构建**: 优化镜像大小和构建速度
+
+## 先决条件
+
+*   **Docker**: 确保您的系统已正确安装并正在运行 Docker。您可以从 [Docker 官方网站](https://www.docker.com/get-started) 下载并安装 Docker Desktop (适用于 Windows 和 macOS) 或 Docker Engine (适用于 Linux)。
+*   **项目代码**: 项目代码已下载到本地。
+*   **认证文件**: 首次运行需要在主机上完成认证文件获取，Docker环境目前仅支持日常运行。
+
+## 🔧 Docker 环境规格
+
+*   **基础镜像**: Python 3.10-slim-bookworm (稳定且轻量)
+*   **Python版本**: 3.10 (在容器内运行，与主机Python版本无关)
+*   **依赖管理**: Poetry (现代化 Python 依赖管理)
+*   **构建方式**: 多阶段构建 (builder + runtime)
+*   **架构支持**: x86_64 和 ARM64 (Apple Silicon)
+*   **模块化设计**: 完全支持项目的模块化架构
+*   **虚拟环境**: Poetry 自动管理虚拟环境
+
+## 1. 理解项目中的 Docker 相关文件
+
+在项目根目录下，您会找到以下与 Docker 配置相关的文件：
+
+*   **[`Dockerfile`](./Dockerfile:1):** 这是构建 Docker 镜像的蓝图。它定义了基础镜像、依赖项安装、代码复制、端口暴露以及容器启动时执行的命令。
+*   **[`.dockerignore`](./.dockerignore:1):** 这个文件列出了在构建 Docker 镜像时应忽略的文件和目录。这有助于减小镜像大小并加快构建速度，例如排除 `.git` 目录、本地开发环境文件等。
+*   **[`supervisord.conf`](./supervisord.conf:1):** (如果项目使用 Supervisor) Supervisor 是一个进程控制系统，它允许用户在类 UNIX 操作系统上监控和控制多个进程。此配置文件定义了 Supervisor 应如何管理应用程序的进程 (例如，主服务和流服务)。
+
+## 2. 构建 Docker 镜像
+
+要构建 Docker 镜像，请在项目根目录下打开终端或命令行界面，然后执行以下命令：
+
+```bash
+# 方法 1: 使用 docker compose (推荐)
+cd docker
+docker compose build
+
+# 方法 2: 直接使用 docker build (在项目根目录执行)
+docker build -f docker/Dockerfile -t ai-studio-proxy:latest .
+```
+
+**命令解释:**
+
+*   `docker build`: 这是 Docker CLI 中用于构建镜像的命令。
+*   `-t ai-studio-proxy:latest`: `-t` 参数用于为镜像指定一个名称和可选的标签 (tag)，格式为 `name:tag`。
+    *   `ai-studio-proxy`: 是您为镜像选择的名称。
+    *   `latest`: 是标签，通常表示这是该镜像的最新版本。您可以根据版本控制策略选择其他标签，例如 `ai-studio-proxy:1.0`。
+*   `.`: (末尾的点号) 指定了 Docker 构建上下文的路径。构建上下文是指包含 [`Dockerfile`](./Dockerfile:1) 以及构建镜像所需的所有其他文件和目录的本地文件系统路径。点号表示当前目录。Docker 守护进程会访问此路径下的文件来执行构建。
+
+构建过程可能需要一些时间，具体取决于您的网络速度和项目依赖项的多少。成功构建后，您可以使用 `docker images` 命令查看本地已有的镜像列表，其中应包含 `ai-studio-proxy:latest`。
+
+## 3. 运行 Docker 容器
+
+镜像构建完成后，您可以选择以下两种方式来运行容器：
+
+### 方式 A: 使用 Docker Compose (推荐)
+
+Docker Compose 提供了更简洁的配置管理方式，特别适合使用 `.env` 文件：
+
+```bash
+# 1. 准备配置文件 (进入 docker 目录)
+cd docker
+cp .env.docker .env
+# 编辑 .env 文件以适应您的需求
+
+# 2. 使用 Docker Compose 启动 (在 docker 目录下)
+docker compose up -d
+
+# 3. 查看日志
+docker compose logs -f
+
+# 4. 停止服务
+docker compose down
+```
+
+### 方式 B: 使用 Docker 命令
+
+您也可以使用传统的 Docker 命令来创建并运行容器：
+
+### 方法 1: 使用 .env 文件 (推荐)
+
+```bash
+docker run -d \
+    -p <宿主机_服务端口>:2048 \
+    -p <宿主机_流端口>:3120 \
+    -v "$(pwd)/../auth_profiles":/app/auth_profiles \
+    -v "$(pwd)/.env":/app/.env \
+    # 可选: 如果您想使用自己的 SSL/TLS 证书，请取消下面一行的注释���
+    # 请确保宿主机上的 'certs/' 目录存在，并且其中包含应用程序所需的证书文件。
+    # -v "$(pwd)/../certs":/app/certs \
+    --name ai-studio-proxy-container \
+    ai-studio-proxy:latest
+```
+
+### 方法 2: 使用环境变量 (传统方式)
+
+```bash
+docker run -d \
+    -p <宿主机_服务端口>:2048 \
+    -p <宿主机_流端口>:3120 \
+    -v "$(pwd)/../auth_profiles":/app/auth_profiles \
+    # 可选: 如果您想使用自己的 SSL/TLS 证书，请取消下面一行的注释。
+    # 请确保宿主机上的 'certs/' 目录存在，并且其中包含应用程序所需的证书文件。
+    # -v "$(pwd)/../certs":/app/certs \
+    -e PORT=8000 \
+    -e DEFAULT_FASTAPI_PORT=2048 \
+    -e DEFAULT_CAMOUFOX_PORT=9222 \
+    -e STREAM_PORT=3120 \
+    -e SERVER_LOG_LEVEL=INFO \
+    -e DEBUG_LOGS_ENABLED=false \
+    -e AUTO_CONFIRM_LOGIN=true \
+    # 可选: 如果您需要设置代理，请取消下面的注释
+    # -e HTTP_PROXY="http://your_proxy_address:port" \
+    # -e HTTPS_PROXY="http://your_proxy_address:port" \
+    # -e UNIFIED_PROXY_CONFIG="http://your_proxy_address:port" \
+    --name ai-studio-proxy-container \
+    ai-studio-proxy:latest
+```
+
+**命令解释:**
+
+*   `docker run`: 这是 Docker CLI 中用于从镜像创建并启动容器的命令。
+*   `-d`: 以“分离模式”(detached mode) 运行容器。这意味着容器将在后台运行，您的终端提示符将立即可用，而不会被容器的日志输出占用。
+*   `-p <宿主机_服务端口>:2048`: 端口映射 (Port mapping)。
+    *   此参数将宿主机的某个端口映射到容器内部的 `2048` 端口。`2048` 是应用程序主服务在容器内监听的端口。
+    *   您需要将 `<宿主机_服务端口>` 替换为您希望在宿主机上用于访问此服务的实际端口号 (例如，如果您想通过宿主机的 `8080` 端口访问服务，则使用 `-p 8080:2048`)。
+*   `-p <宿主机_流端口>:3120`: 类似地，此参数将宿主机的某个端口映射到容器内部的 `3120` 端口，这是应用程序流服务在容器内监听的端口。
+    *   您需要将 `<宿主机_流端口>` 替换为您希望在宿主机上用于访问流服务的实际端口号 (例如 `-p 8081:3120`)。
+*   `-v "$(pwd)/../auth_profiles":/app/auth_profiles`: 卷挂载 (Volume mounting)。
+    *   此参数将宿主机当前工作目录 (`$(pwd)`) 下的 `auth_profiles/` 目录挂载到容器内的 `/app/auth_profiles/` 目录。
+    *   这样做的好处是：
+        *   **持久化数据:** 即使容器被删除，`auth_profiles/` 中的数据仍保留在宿主机上。
+        *   **方便配置:** 您可以直接在宿主机上修改 `auth_profiles/` 中的文件，更改会实时反映到容器中 (取决于应用程序如何读取这些文件)。
+    *   **重要:** 在运行命令前，请确保宿主机上的 `auth_profiles/` 目录已存在。如果应用程序期望在此目录中找到特定的配置文件，请提前准备好。
+*   `# -v "$(pwd)/../certs":/app/certs` (可选，已注释): 挂载自定义证书。
+    *   如果您希望应用程序使用您自己的 SSL/TLS 证书而不是自动生成的证书，可以取消此行的注释。
+    *   它会将宿主机当前工作目录下的 `certs/` 目录挂载到容器内的 `/app/certs/` 目录。
+    *   **重要:** 如果启用此选项，请确保宿主机上的 `certs/` 目录存在，并且其中包含应用程序所需的证书文件 (通常是 `server.crt` 和 `server.key` 或类似名称的文件)。应用程序也需要被配置为从 `/app/certs/` 读取这些证书。
+*   `-e SERVER_PORT=2048`: 设置环境变量。
+    *   `-e` 参数用于在容器内设置环境变量。
+    *   这里，我们将 `SERVER_PORT` 环境变量设置为 `2048`。应用程序在容器内会读取此变量来确定其主服务应监听哪个端口。这应与 [`Dockerfile`](./Dockerfile:1) 中 `EXPOSE` 指令以及 [`supervisord.conf`](./supervisord.conf:1) (如果使用) 中的配置相匹配。
+*   `-e STREAM_PORT=3120`: 类似地，设置 `STREAM_PORT` 环境变量为 `3120`，供应用程序的流服务使用。
+*   `# -e INTERNAL_CAMOUFOX_PROXY="http://your_proxy_address:port"` (可选，已注释): 设置内部 Camoufox 代理。
+    *   如果您的应用程序需要通过一个特定的内部代理服务器来访问 Camoufox 或其他外部服务，可以取消此行的注释，并将 `"http://your_proxy_address:port"` 替换为实际的代理服务器地址和端口 (例如 `http://10.0.0.5:7890` 或 `socks5://proxy-user:proxy-pass@10.0.0.10:1080`)。
+*   `--name ai-studio-proxy-container`: 为正在运行的容器指定一个名称。
+    *   这使得管理容器更加方便。例如，您可以使用 `docker stop ai-studio-proxy-container` 来停止这个容器，或使用 `docker logs ai-studio-proxy-container` 来查看其日志。
+    *   如果您不指定名称，Docker 会自动为容器生成一个随机名称。
+*   `ai-studio-proxy:latest`: 指定要运行的镜像的名称和标签。这必须与您在 `docker build` 命令中使用的名称和标签相匹配。
+
+**首次运行前的重要准备:**
+
+### 配置文件准备
+
+1. **创建 `.env` 配置文件 (推荐):**
+   ```bash
+   # 复制配置模板 (在项目 docker 目录下执行)
+   cp .env.docker .env
+
+   # 编辑配置文件
+   nano .env  # 或使用其他编辑器
+   ```
+
+   **`.env` 文件的优势:**
+   - ✅ **版本更新无忧**: 一个 `git pull` 就完成更新，无需重新配置
+   - ✅ **配置集中管理**: 所有配置项统一在 `.env` 文件中
+   - ✅ **Docker 兼容**: 容器会自动读取挂载的 `.env` 文件
+   - ✅ **安全性**: `.env` 文件已被 `.gitignore` 忽略，不会泄露配置
+
+2. **创建 `auth_profiles/` 目录:** 在项目根目录下 (与 [`Dockerfile`](./Dockerfile:1) 同级)，手动创建一个名为 `auth_profiles` 的目录。如果您的应用程序需要初始的认证配置文件，请将它们放入此目录中。
+
+3. **(可选) 创建 `certs/` 目录:** 如果您计划使用自己的证书并取消了相关卷挂载行的注释，请在项目根目录下创建一个名为 `certs` 的目录，并将您的证书文件 (例如 `server.crt`, `server.key`) 放入其中。
+
+## 4. 环境变量配置详解
+
+### 使用 .env 文件配置 (推荐)
+
+项目现在支持通过 `.env` 文件进行配置管理。在 Docker 环境中，您只需要将 `.env` 文件挂载到容器中即可：
+
+```bash
+# 挂载 .env 文件到容器
+-v "$(pwd)/.env":/app/.env
+```
+
+### 常用配置项
+
+以下是 Docker 环境中常用的配置项：
+
+```env
+# 服务端口配置
+PORT=8000
+DEFAULT_FASTAPI_PORT=2048
+DEFAULT_CAMOUFOX_PORT=9222
+STREAM_PORT=3120
+
+# 代理配置
+HTTP_PROXY=http://127.0.0.1:7890
+HTTPS_PROXY=http://127.0.0.1:7890
+UNIFIED_PROXY_CONFIG=http://127.0.0.1:7890
+
+# 日志配置
+SERVER_LOG_LEVEL=INFO
+DEBUG_LOGS_ENABLED=false
+TRACE_LOGS_ENABLED=false
+
+# 认证配置
+AUTO_CONFIRM_LOGIN=true
+AUTO_SAVE_AUTH=false
+AUTH_SAVE_TIMEOUT=30
+
+# 脚本注入配置 v3.0 (重大升级)
+ENABLE_SCRIPT_INJECTION=true
+USERSCRIPT_PATH=browser_utils/more_modles.js
+# 注意：MODEL_CONFIG_PATH 已废弃，现在直接从油猴脚本解析模型数据
+# v3.0 使用 Playwright 原生网络拦截，100% 可靠
+
+# API 默认参数
+DEFAULT_TEMPERATURE=1.0
+DEFAULT_MAX_OUTPUT_TOKENS=65536
+DEFAULT_TOP_P=0.95
+```
+
+### 配置优先级
+
+在 Docker 环境中，配置的优先级顺序为：
+
+1. **Docker 运行时环境变量** (`-e` 参数) - 最高优先级
+2. **挂载的 .env 文件** - 中等优先级
+3. **Dockerfile 中的 ENV** - 最低优先级
+
+### 示例：完整的 Docker 运行命令
+
+```bash
+# 使用 .env 文件的完整示例
+docker run -d \
+    -p 8080:2048 \
+    -p 8081:3120 \
+    -v "$(pwd)/../auth_profiles":/app/auth_profiles \
+    -v "$(pwd)/.env":/app/.env \
+    --name ai-studio-proxy-container \
+    ai-studio-proxy:latest
+```
+
+## 5. 管理正在运行的容器
+
+一旦容器启动，您可以使用以下 Docker 命令来管理它：
+
+*   **查看正在运行的容器:**
+    ```bash
+    docker ps
+    ```
+    (如果您想查看所有容器，包括已停止的，请使用 `docker ps -a`)
+
+*   **查看容器日志:**
+    ```bash
+    docker logs ai-studio-proxy-container
+    ```
+    (如果您想持续跟踪日志输出，可以使用 `-f` 参数: `docker logs -f ai-studio-proxy-container`)
+
+*   **停止容器:**
+    ```bash
+    docker stop ai-studio-proxy-container
+    ```
+
+*   **启动已停止的容器:**
+    ```bash
+    docker start ai-studio-proxy-container
+    ```
+
+*   **重启容器:**
+    ```bash
+    docker restart ai-studio-proxy-container
+    ```
+
+*   **进入容器内部 (获取一个交互式 shell):**
+    ```bash
+    docker exec -it ai-studio-proxy-container /bin/bash
+    ```
+    (或者 `/bin/sh`，取决于容器基础镜像中可用的 shell。这对于调试非常有用。)
+
+*   **删除容器:**
+    首先需要停止容器，然后才能删除它。
+    ```bash
+    docker stop ai-studio-proxy-container
+    docker rm ai-studio-proxy-container
+    ```
+    (如果您想强制删除正在运行的容器，可以使用 `docker rm -f ai-studio-proxy-container`，但不建议这样做，除非您知道自己在做什么。)
+
+## 5. 更新应用程序
+
+当您更新了应用程序代码并希望部署新版本时，通常需要执行以下步骤：
+
+1.  **停止并删除旧的容器** (如果它正在使用相同的端口或名称)：
+    ```bash
+    docker stop ai-studio-proxy-container
+    docker rm ai-studio-proxy-container
+    ```
+2.  **重新构建 Docker 镜像** (确保您在包含最新代码和 [`Dockerfile`](./Dockerfile:1) 的目录中)：
+    ```bash
+    docker build -t ai-studio-proxy:latest .
+    ```
+3.  **使用新的镜像运行新的容���** (使用与之前相同的 `docker run` 命令，或根据需要进行调整)：
+    ```bash
+    docker run -d \
+        -p <宿主机_服务端口>:2048 \
+        # ... (其他参数与之前相同) ...
+        --name ai-studio-proxy-container \
+        ai-studio-proxy:latest
+    ```
+
+## 6. 清理
+
+*   **删除指定的 Docker 镜像:**
+    ```bash
+    docker rmi ai-studio-proxy:latest
+    ```
+    (注意：如果存在基于此镜像的容器，您需要先删除这些容器。)
+
+*   **删除所有未使用的 (悬空) 镜像、容器、网络和卷:**
+    ```bash
+    docker system prune
+    ```
+    (如果想删除所有未使用的镜像，不仅仅是悬空的，可以使用 `docker system prune -a`)
+    **警告:** `prune` 命令会删除数据，请谨慎使用。
+
+希望本教程能帮助您成功地通过 Docker 部署和运行 AI Studio Proxy API 项目！
+
+## 脚本注入配置 (v3.0 新功能) 🆕

+ENABLE_SCRIPT_INJECTION=true
+
+# 油猴脚本文件路径（容器内路径）
+# 模型数据直接从此脚本文件中解析，无需额外配置文件
+USERSCRIPT_PATH=browser_utils/more_modles.js
+```
+
+### 自定义脚本和模型配置
+
+如果您想使用自定义的脚本或模型配置：
+
+1. **自定义脚本配置**：
+   ```bash
+   # 在主机上创建自定义脚本文件
+   cp browser_utils/more_modles.js browser_utils/my_script.js
+   # 编辑 my_script.js 中的 MODELS_TO_INJECT 数组
+
+   # 在 docker-compose.yml 中取消注释并修改挂载行：
+   # - ../browser_utils/my_script.js:/app/browser_utils/more_modles.js:ro
+
+   # 或者在 .env 中修改路径：
+   # USERSCRIPT_PATH=browser_utils/my_script.js
+   ```
+
+2. **自定义脚本**：
+   ```bash
+   # 将自定义脚本放在 browser_utils/ 目录
+   cp your_custom_script.js browser_utils/custom_script.js
+
+   # 在 .env 中修改路径：
+   # USERSCRIPT_PATH=browser_utils/custom_script.js
+   ```
+
+### Docker Compose 挂载配置
+
+在 `docker-compose.yml` 中，您可以取消注释以下行来挂载自定义文件：
+
+```yaml
+volumes:
+  # 挂载自定义模型配置
+  - ../browser_utils/model_configs.json:/app/browser_utils/model_configs.json:ro
+  # 挂载自定义脚本目录
+  - ../browser_utils/custom_scripts:/app/browser_utils/custom_scripts:ro
+```
+
+### 注意事项
+
+- 脚本或配置文件更新后需要重启容器
+- 如果脚本注入失败，不会影响主要功能
+- 可以通过容器日志查看脚本注入状态
+
+## 注意事项
+
+1. **认证文件**: Docker 部署需要预先在主机上获取有效的认证文件，并将其放置在 `auth_profiles/active/` 目录中。
+2. **模块化架构**: 项目采用模块化设计，所有配置和代码都已经过优化，无需手动修改。
+3. **端口配置**: 确保宿主机上的端口未被占用，默认使用 2048 (主服务) 和 3120 (流式代理)。
+4. **日志查看**: 可以通过 `docker logs` 命令查看容器运行日志，便于调试和监控。
+5. **脚本注入**: 新增的脚本注入功能默认启用，可通过 `ENABLE_SCRIPT_INJECTION=false` 禁用。

+
+### 进入容器检查
+
+```bash
+# 进入容器
+docker compose exec ai-studio-proxy /bin/bash
+
+# 检查脚本文件
+cat /app/browser_utils/more_modles.js
+
+# 检查脚本文件列表
+ls -la /app/browser_utils/*.js
+
+# 退出容器
+exit
+```
+
+## 故障排除
+
+### 脚本注入失败
+
+1. **检查配置文件路径**：
+   ```bash
+   docker compose exec ai-studio-proxy ls -la /app/browser_utils/
+   ```
+
+2. **检查文件权限**：
+   ```bash
+   docker compose exec ai-studio-proxy cat /app/browser_utils/more_modles.js
+   ```
+
+3. **查看详细错误日志**：
+   ```bash
+   docker compose logs | grep -A 5 -B 5 "脚本注入"
+   ```
+
+### 脚本文件无效
+
+1. **验证 JavaScript 格式**：
+   ```bash
+   # 在主机上验证 JavaScript 语法
+   node -c browser_utils/more_modles.js
+   ```
+
+2. **检查必需字段**：
+   确保每个模型都有 `name` 和 `displayName` 字段。
+
+### 禁用脚本注入
+
+如果遇到问题，可以临时禁用：
+
+```bash
+# 在 .env 文件中设置
+echo "ENABLE_SCRIPT_INJECTION=false" >> .env
+
+# 重启容器
+docker compose restart
+```
+
+## 高级配置
+
+### 使用自定义脚本
+
+```bash
+# 1. 将自定义脚本放在 browser_utils/ 目录
+cp your_custom_script.js ../browser_utils/custom_injector.js
+
+# 2. 在 .env 中修改脚本路径
+echo "USERSCRIPT_PATH=browser_utils/custom_injector.js" >> .env
+
+# 3. 重启容器
+docker compose restart
+```
+
+### 多环境配置
+
+```bash
+# 开发环境
+cp .env.docker .env.dev
+# 编辑 .env.dev
+
+# 生产环境
+cp .env.docker .env.prod
+# 编辑 .env.prod
+
+# 使用特定环境启动
+cp .env.prod .env
+docker compose up -d
+```
+
+## 注意事项
+
+1. **文件挂载**: 确保主机上的文件路径正确
+2. **权限问题**: Docker 容器内的文件权限可能需要调整
+3. **重启生效**: 配置更改后需要重启容器
+4. **日志监控**: 通过日志确认脚本注入状态
+5. **备份配置**: 建议备份工作的配置文件
+
+## 示例配置文件

+# 高级配置指南
+
+本文档介绍项目的高级配置选项和功能。
+
+## 代理配置管理
+
+### 代理配置优先级
+
+项目采用统一的代理配置管理系统，按以下优先级顺序确定代理设置：
+
+1. **`--internal-camoufox-proxy` 命令行参数** (最高优先级)
+   - 明确指定代理：`--internal-camoufox-proxy 'http://127.0.0.1:7890'`
+   - 明确禁用代理：`--internal-camoufox-proxy ''`
+2. **`UNIFIED_PROXY_CONFIG` 环境变量** (推荐，.env 文件配置)
+3. **`HTTP_PROXY` 环境变量**
+4. **`HTTPS_PROXY` 环境变量**
+5. **系统代理设置** (Linux 下的 gsettings，最低优先级)
+
+**推荐配置方式**:
+```env
+# .env 文件中统一配置代理
+UNIFIED_PROXY_CONFIG=http://127.0.0.1:7890
+# 或禁用代理
+UNIFIED_PROXY_CONFIG=
+```
+
+### 统一代理配置
+
+此代理配置会同时应用于 Camoufox 浏览器和流式代理服务的上游连接，确保整个系统的代理行为一致。
+
+## 响应获取模式配置
+
+### 模式1: 优先使用集成的流式代理 (默认推荐)
+
+**推荐使用 .env 配置方式**:
+```env
+# .env 文件配置
+DEFAULT_FASTAPI_PORT=2048
+STREAM_PORT=3120
+UNIFIED_PROXY_CONFIG=
+```
+
+```bash
+# 简化启动命令 (推荐)
+python launch_camoufox.py --headless
+
+# 传统命令行方式 (仍然支持)
+python launch_camoufox.py --headless --server-port 2048 --stream-port 3120 --helper '' --internal-camoufox-proxy ''
+```
+
+# 启用统一代理配置（同时应用于浏览器和流式代理）
+python launch_camoufox.py --headless --server-port 2048 --stream-port 3120 --helper '' --internal-camoufox-proxy 'http://127.0.0.1:7890'
+```
+
+在此模式下，主服务器会优先尝试通过端口 `3120` (或指定的 `--stream-port`) 上的集成流式代理获取响应。如果失败，则回退到 Playwright 页面交互。
+
+### 模式2: 优先使用外部 Helper 服务 (禁用集成流式代理)
+
+```bash
+# 基本外部Helper模式，明确禁用代理
+python launch_camoufox.py --headless --server-port 2048 --stream-port 0 --helper 'http://your-helper-service.com/api/getStreamResponse' --internal-camoufox-proxy ''
+
+# 外部Helper模式 + 统一代理配置
+python launch_camoufox.py --headless --server-port 2048 --stream-port 0 --helper 'http://your-helper-service.com/api/getStreamResponse' --internal-camoufox-proxy 'http://127.0.0.1:7890'
+```
+
+在此模式下，主服务器会优先尝试通过 `--helper` 指定的端点获取响应 (需要有效的 `auth_profiles/active/*.json` 以提取 `SAPISID`)。如果失败，则回退到 Playwright 页面交互。
+
+### 模式3: 仅使用 Playwright 页面交互 (禁用所有流式代理和 Helper)
+
+```bash
+# 纯Playwright模式，明确禁用代理
+python launch_camoufox.py --headless --server-port 2048 --stream-port 0 --helper '' --internal-camoufox-proxy ''
+
+# Playwright模式 + 统一代理配置
+python launch_camoufox.py --headless --server-port 2048 --stream-port 0 --helper '' --internal-camoufox-proxy 'http://127.0.0.1:7890'
+```
+
+在此模式下，主服务器将仅通过 Playwright 与 AI Studio 页面交互 (模拟点击"编辑"或"复制"按钮) 来获取响应。这是传统的后备方法。
+
+## 虚拟显示模式 (Linux)
+
+### 关于 `--virtual-display`
+
+- **为什么使用**: 与标准的无头模式相比，虚拟显示模式通过创建一个完整的虚拟 X 服务器环境 (Xvfb) 来运行浏览器。这可以模拟一个更真实的桌面环境，从而可能进一步降低被网站检测为自动化脚本或机器人的风险
+- **什么时候使用**: 当您在 Linux 环境下运行，并且希望以无头模式操作
+- **如何使用**:
+  1. 确保您的 Linux 系统已安装 `xvfb`
+  2. 在运行时添加 `--virtual-display` 标志：
+     ```bash
+     python launch_camoufox.py --virtual-display --server-port 2048 --stream-port 3120 --internal-camoufox-proxy ''
+     ```
+
+## 流式代理服务配置
+
+### 自签名证书管理
+
+集成的流式代理服务会在 `certs` 文件夹内生成自签名的根证书。
+
+#### 证书删除与重新生成
+
+- 可以删除 `certs` 目录下的根证书 (`ca.crt`, `ca.key`)，代码会在下次启动时重新生成
+- **重要**: 删除根证书时，**强烈建议同时删除 `certs` 目录下的所有其他文件**，避免信任链错误
+
+#### 手动生成证书
+
+如果需要重新生成证书，可以使用以下命令：
+
+```bash
+openssl genrsa -out certs/ca.key 2048
+openssl req -new -x509 -days 3650 -key certs/ca.key -out certs/ca.crt -subj "/C=CN/ST=Shanghai/L=Shanghai/O=AiStudioProxyHelper/OU=CA/CN=AiStudioProxyHelper CA/emailAddress=ca@example.com"
+openssl rsa -in certs/ca.key -out certs/ca.key
+```
+
+### 工作原理
+
+流式代理服务的特性：
+
+- 创建一个 HTTP 代理服务器（默认端口：3120）
+- 拦截针对 Google 域名的 HTTPS 请求
+- 使用自签名 CA 证书动态自动生成服务器证书
+- 将 AIStudio 响应解析为 OpenAI 兼容格式
+
+## 模型排除配置
+
+### excluded_models.txt
+
+项目根目录下的 `excluded_models.txt` 文件可用于从 `/v1/models` 端点返回的列表中排除特定的模型 ID。
+
+每行一个模型ID，例如：
+```
+gemini-1.0-pro
+gemini-1.0-pro-vision
+deprecated-model-id
+```
+
+## 脚本注入高级配置 🆕
+
+### 概述
+
+脚本注入功能允许您动态挂载油猴脚本来增强 AI Studio 的模型列表。该功能使用 Playwright 原生网络拦截技术，确保 100% 可靠性。
+
+### 工作原理
+
+1. **双重拦截机制**：
+   - **Playwright 路由拦截**：在网络层面直接拦截和修改模型列表响应
+   - **JavaScript 脚本注入**：作为备用方案，确保万无一失
+
+2. **自动模型解析**：
+   - 从油猴脚本中自动解析 `MODELS_TO_INJECT` 数组
+   - 前端和后端使用相同的模型数据源
+   - 无需手动维护模型配置文件
+
+### 高级配置选项
+
+#### 自定义脚本路径
+
+```env
+# 使用自定义脚本文件
+USERSCRIPT_PATH=custom_scripts/my_enhanced_script.js
+```
+
+#### 自定义脚本配置
+
+```env
+# 使用自定义脚本文件（模型数据直接从脚本解析）
+USERSCRIPT_PATH=configs/production_script.js
+```
+
+#### 调试模式
+
+```env
+# 启用详细的脚本注入日志
+DEBUG_LOGS_ENABLED=true
+ENABLE_SCRIPT_INJECTION=true
+```
+
+### 自定义脚本开发
+
+#### 脚本格式要求
+
+您的自定义脚本必须包含 `MODELS_TO_INJECT` 数组：
+
+```javascript
+const MODELS_TO_INJECT = [
+    {
+        name: 'models/your-custom-model',
+        displayName: '🚀 Your Custom Model',
+        description: 'Custom model description'
+    },
+    // 更多模型...
+];
+```
+
+#### 脚本模型数组格式
+
+```javascript
+const MODELS_TO_INJECT = [
+    {
+        name: 'models/custom-model-1',
+        displayName: `🎯 Custom Model 1 (Script ${SCRIPT_VERSION})`,
+        description: `First custom model injected by script ${SCRIPT_VERSION}`
+    },
+    {
+        name: 'models/custom-model-2',
+        displayName: `⚡ Custom Model 2 (Script ${SCRIPT_VERSION})`,
+        description: `Second custom model injected by script ${SCRIPT_VERSION}`
+    }
+];
+```
+```
+
+### 网络拦截技术细节
+
+#### Playwright 路由拦截
+
+```javascript
+// 系统会自动设置类似以下的路由拦截
+await context.route("**/*", async (route) => {
+    const request = route.request();
+    if (request.url().includes('alkalimakersuite') &&
+        request.url().includes('ListModels')) {
+        // 拦截并修改模型列表响应
+        const response = await route.fetch();
+        const modifiedBody = await modifyModelListResponse(response);
+        await route.fulfill({ response, body: modifiedBody });
+    } else {
+        await route.continue_();
+    }
+});
+```
+
+#### 响应修改流程
+
+1. **请求识别**：检测包含 `alkalimakersuite` 和 `ListModels` 的请求
+2. **响应获取**：获取原始模型列表响应
+3. **数据解析**：解析 JSON 响应并处理反劫持前缀
+4. **模型注入**：将自定义模型注入到响应中
+5. **响应返回**：返回修改后的响应给浏览器
+
+### 故障排除
+
+#### 脚本注入失败
+
+1. **检查脚本文件**：
+   ```bash
+   # 验证脚本文件存在且可读
+   ls -la browser_utils/more_modles.js
+   cat browser_utils/more_modles.js | head -20
+   ```
+
+2. **检查日志输出**：
+   ```bash
+   # 查看脚本注入相关日志
+   python launch_camoufox.py --debug | grep -i "script\|inject"
+   ```
+
+3. **验证配置**：
+   ```bash
+   # 检查环境变量配置
+   grep SCRIPT .env
+   ```
+
+#### 模型未显示
+
+1. **前端检查**：在浏览器开发者工具中查看是否有 JavaScript 错误
+2. **后端检查**：查看 API 响应是否包含注入的模型
+3. **网络检查**：确认网络拦截是否正常工作
+
+### 性能优化
+
+#### 脚本缓存
+
+系统会自动缓存解析的模型列表，避免重复解析：
+
+```python
+# 系统内部缓存机制
+if not hasattr(self, '_cached_models'):
+    self._cached_models = parse_userscript_models(script_content)
+return self._cached_models
+```
+
+#### 网络拦截优化
+
+- 只拦截必要的请求，其他请求直接通过
+- 使用高效的 JSON 解析和序列化
+- 最小化响应修改的开销
+
+### 安全考虑
+
+#### 脚本安全
+
+- 脚本在受控的浏览器环境中执行
+- 不会影响主机系统安全
+- 建议只使用可信的脚本源
+
+#### 网络安全
+
+- 网络拦截仅限于特定的模型列表请求
+- 不会拦截或修改其他敏感请求
+- 所有修改都在本地进行，不会发送到外部服务器
+
+## GUI 启动器高级功能
+
+### 本地LLM模拟服务
+
+GUI 集成了启动和管理一个本地LLM模拟服务的功能：
+
+- **功能**: 监听 `11434` ���口，模拟部分 Ollama API 端点和 OpenAI 兼容的 `/v1/chat/completions` 端点
+- **启动**: 在 GUI 的"启动选项"区域，点击"启动本地LLM模拟服务"按钮
+- **依赖检测**: 启动前会自动检测 `localhost:2048` 端口是否可用
+- **用途**: 主要用于测试客户端与 Ollama 或 OpenAI 兼容 API 的对接
+
+### 端口进程管理
+
+GUI 提供端口进程管理功能：
+
+- 查询指定端口上当前正在运行的进程
+- 选择并尝试停止在指定端口上找到的进程
+- 手动输入 PID 终止进程
+
+## 环境变量配置
+
+### 代理配置
+
+```bash
+# 使用环境变量配置代理（不推荐，建议明确指定）
+export HTTP_PROXY=http://127.0.0.1:7890
+export HTTPS_PROXY=http://127.0.0.1:7890
+python launch_camoufox.py --headless --server-port 2048 --stream-port 3120 --helper ''
+```
+
+### 日志控制
+
+详见 [日志控制指南](logging-control.md)。
+
+## 重要提示
+
+### 代理配置建议
+
+**强烈建议在所有 `launch_camoufox.py` 命令中明确指定 `--internal-camoufox-proxy` 参数，即使其值为空字符串 (`''`)，以避免意外使用系统环境变量中的代理设置。**
+
+### 参数控制限制
+
+API 请求中的模型参数（如 `temperature`, `max_output_tokens`, `top_p`, `stop`）**仅在通过 Playwright 页面交互获取响应时生效**。当使用集成的流式代理或外部 Helper 服务时，这些参数的传递和应用方式取决于这些服务自身的实现。
+
+### 首次访问性能
+
+当通过流式代理首次访问一个新的 HTTPS 主机时，服务需要为该主机动态生成并签署一个新的子证书。这个过程可能会比较耗时，导致对该新主机的首次连接请求响应较慢。一旦证书生成并缓存后，后续访问同一主机将会显著加快。

+# API 使用指南
+
+本指南详细介绍如何使用 AI Studio Proxy API 的各种功能和端点。
+
+## 服务器配置
+
+代理服务器默认监听在 `http://127.0.0.1:2048`。端口可以通过以下方式配置：
+
+- **环境变量**: 在 `.env` 文件中设置 `PORT=2048` 或 `DEFAULT_FASTAPI_PORT=2048`
+- **命令行参数**: 使用 `--server-port` 参数
+- **GUI 启动器**: 在图形界面中直接配置端口
+
+推荐使用 `.env` 文件进行配置管理，详见 [环境变量配置指南](environment-configuration.md)。
+
+## API 密钥配置
+
+### key.txt 文件配置
+
+项目使用 `auth_profiles/key.txt` 文件来管理 API 密钥：
+
+**文件位置**: 项目根目录下的 `key.txt` 文件
+
+**文件格式**: 每行一个 API 密钥，支持空行和注释
+
+```
+your-api-key-1
+your-api-key-2
+# 这是注释行，会被忽略
+
+another-api-key
+```
+
+**自动创建**: 如果 `key.txt` 文件不存在，系统会自动创建一个空文件
+
+### 密钥管理方法
+
+#### 手动编辑文件
+
+直接编辑 `key.txt` 文件添加或删除密钥：
+
+```bash
+# 添加密钥
+echo "your-new-api-key" >> key.txt
+
+# 查看当前密钥（注意安全）
+cat key.txt
+```
+
+#### 通过 Web UI 管理
+
+在 Web UI 的"设置"标签页中可以：
+
+- 验证密钥有效性
+- 查看服务器上配置的密钥列表（需要先验证）
+- 测试特定密钥
+
+### 密钥验证机制
+
+**验证逻辑**:
+
+- 如果 `key.txt` 为空或不存在，则不需要 API 密钥验证
+- 如果配置了密钥，则所有 API 请求都需要提供有效的密钥
+- 密钥验证支持两种认证头格式
+
+**安全特性**:
+
+- 密钥在日志中会被打码显示（如：`abcd****efgh`）
+- Web UI 中的密钥列表也会打码显示
+- 支持最小长度验证（至少 8 个字符）
+
+## API 认证流程
+
+### Bearer Token 认证
+
+项目支持标准的 OpenAI 兼容认证方式：
+
+**主要认证方式** (推荐):
+
+```bash
+Authorization: Bearer your-api-key
+```
+
+**备用认证方式** (向后兼容):
+
+```bash
+X-API-Key: your-api-key
+```
+
+### 认证行为
+
+**无密钥配置时**:
+
+- 所有 API 请求都不需要认证
+- `/api/info` 端点会显示 `"api_key_required": false`
+
+**有密钥配置时**:
+
+- 所有 `/v1/*` 路径的 API 请求都需要有效的密钥
+- 除外路径：`/v1/models`, `/health`, `/docs` 等公开端点
+- 认证失败返回 `401 Unauthorized` 错误
+
+### 客户端配置示例
+
+#### curl 示例
+
+```bash
+# 使用 Bearer token
+curl -X POST http://127.0.0.1:2048/v1/chat/completions \
+  -H "Authorization: Bearer your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{"messages": [{"role": "user", "content": "Hello"}]}'
+
+# 使用 X-API-Key 头
+curl -X POST http://127.0.0.1:2048/v1/chat/completions \
+  -H "X-API-Key: your-api-key" \
+  -H "Content-Type: application/json" \
+  -d '{"messages": [{"role": "user", "content": "Hello"}]}'
+```
+
+#### Python requests 示例
+
+```python
+import requests
+
+headers = {
+    "Authorization": "Bearer your-api-key",
+    "Content-Type": "application/json"
+}
+
+data = {
+    "messages": [{"role": "user", "content": "Hello"}]
+}
+
+response = requests.post(
+    "http://127.0.0.1:2048/v1/chat/completions",
+    headers=headers,
+    json=data
+)
+```
+
+## API 端点
+
+### 聊天接口
+
+**端点**: `POST /v1/chat/completions`
+
+- 请求体与 OpenAI API 兼容，需要 `messages` 数组。
+- `model` 字段现在用于指定目标模型，代理会尝试在 AI Studio 页面切换到该模型。如果为空或为代理的默认模型名，则使用 AI Studio 当前激活的模型。
+- `stream` 字段控制流式 (`true`) 或非流式 (`false`) 输出。
+- 现在支持 `temperature`, `max_output_tokens`, `top_p`, `stop` 等参数，代理会尝试在 AI Studio 页面上应用它们。
+- **需要认证**: 如果配置了 API 密钥，此端点需要有效的认证头。
+
+#### 示例 (curl, 非流式, 带参数)
+
+```bash
+curl -X POST http://127.0.0.1:2048/v1/chat/completions \
+-H "Content-Type: application/json" \
+-d '{
+  "model": "gemini-1.5-pro-latest",
+  "messages": [
+    {"role": "system", "content": "Be concise."},
+    {"role": "user", "content": "What is the capital of France?"}
+  ],
+  "stream": false,

+```
+
+### 模型列表
+
+**端点**: `GET /v1/models`
+
+- 返回 AI Studio 页面上检测到的可用模型列表，以及一个代理本身的默认模型条目。
+- 现在会尝试从 AI Studio 动态获取模型列表。如果获取失败，会返回一个后备模型。
+- 支持 [`excluded_models.txt`](../excluded_models.txt) 文件，用于从列表中排除特定的模型 ID。
+- **🆕 脚本注入模型**: 如果启用了脚本注入功能，列表中还会包含通过油猴脚本注入的自定义模型，这些模型会标记为 `"injected": true`。
+
+**脚本注入模型特点**:
+
+- 模型 ID 格式：注入的模型会自动移除 `models/` 前缀，如 `models/kingfall-ab-test` 变为 `kingfall-ab-test`
+- 标识字段：包含 `"injected": true` 字段用于识别
+- 所有者标识：`"owned_by": "ai_studio_injected"`
+- 完全兼容：可以像普通模型一样通过 API 调用
+
+**示例响应**:
+
+```json
+{
+  "object": "list",
+  "data": [
+    {
+      "id": "kingfall-ab-test",
+      "object": "model",
+      "created": 1703123456,
+      "owned_by": "ai_studio_injected",
+      "display_name": "👑 Kingfall",
+      "description": "Kingfall model - Advanced reasoning capabilities",
+      "injected": true
+    }
+  ]
+}
+```
+
+### API 信息
+
+**端点**: `GET /api/info`
+
+- 返回 API 配置信息，如基础 URL 和模型名称。
+
+### 健康检查
+
+**端点**: `GET /health`
+
+- 返回服务器运行状态（Playwright, 浏览器连接, 页面状态, Worker 状态, 队列长度）。
+
+### 队列状态
+
+**端点**: `GET /v1/queue`
+
+- 返回当前请求队列的详细信息。
+
+### 取消请求
+
+**端点**: `POST /v1/cancel/{req_id}`
+
+- 尝试取消仍在队列中等待处理的请求。
+
+### API 密钥管理端点
+
+#### 获取密钥列表
+
+**端点**: `GET /api/keys`
+
+- 返回服务器上配置的所有 API 密钥列表
+- **注意**: 服务器返回完整密钥，打码显示由 Web UI 前端处理
+- **无需认证**: 此端点不需要 API 密钥认证
+
+#### 测试密钥
+
+**端点**: `POST /api/keys/test`
+
+- 验证指定的 API 密钥是否有效
+- 请求体：`{"key": "your-api-key"}`
+- 返回：`{"success": true, "valid": true/false, "message": "..."}`
+- **无需认证**: 此端点不需要 API 密钥认证
+
+#### 添加密钥
+
+**端点**: `POST /api/keys`
+
+- 向服务器添加新的 API 密钥
+- 请求体：`{"key": "your-new-api-key"}`
+- 密钥要求：至少 8 个字符，不能重复
+- **无需认证**: 此端点不需要 API 密钥认证
+
+#### 删除密钥
+
+**端点**: `DELETE /api/keys`
+
+- 从服务器删除指定的 API 密钥
+- 请求体：`{"key": "key-to-delete"}`
+- **无需认证**: 此端点不需要 API 密钥认证
+
+## 配置客户端 (以 Open WebUI 为例)
+
+1. 打开 Open WebUI。
+2. 进入 "设置" -> "连接"。
+3. 在 "模型" 部分，点击 "添加模型"。
+4. **模型名称**: 输入你想要的名字，例如 `aistudio-gemini-py`。
+5. **API 基础 URL**: 输入代理服务器的地址，例如 `http://127.0.0.1:2048/v1` (如果服务器在另一台机器，用其 IP 替换 `127.0.0.1`，并确保端口可访问)。
+6. **API 密钥**: 留空或输入任意字符 (服务器不验证)。
+7. 保存设置。
+8. 现在，你应该可以在 Open WebUI 中选择你在第一步中配置的模型名称并开始聊天了。如果之前配置过，可能需要刷新或重新选择模型以应用新的 API 基地址。
+
+## 重要提示
+
+### 三层响应获取机制与参数控制
+
+- **响应获取优先级**: 项目采用三层响应获取机制，确保高可用性和最佳性能：
+
+  1. **集成流式代理服务 (Stream Proxy)**:
+     - 默认启用，监听端口 `3120` (可通过 `.env` 文件的 `STREAM_PORT` 配置)
+     - 提供最佳性能和稳定性，直接处理 AI Studio 请求
+     - 支持基础参数传递，无需浏览器交互
+  2. **外部 Helper 服务**:
+     - 可选配置，通过 `--helper <endpoint_url>` 参数或 `.env` 配置启用
+     - 需要有效的认证文件 (`auth_profiles/active/*.json`) 提取 `SAPISID` Cookie
+     - 作为流式代理的备用方案
+  3. **Playwright 页面交互**:
+     - 最终后备方案，通过浏览器自动化获取响应
+     - 支持完整的参数控制和模型切换
+     - 通过模拟用户操作（编辑/复制按钮）获取响应
+
+- **参数控制详解**:
+
+  - **流式代理模式**: 支持基础参数 (`model`, `temperature`, `max_tokens` 等)，性能最优
+  - **Helper 服务模式**: 参数支持取决于外部 Helper 服务的具体实现
+  - **Playwright 模式**: 完整支持所有参数，包括 `temperature`, `max_output_tokens`, `top_p`, `stop`, `reasoning_effort`, `tools` 等
+
+- **模型管理**:
+
+  - API 请求中的 `model` 字段用于在 AI Studio 页面切换模型
+  - 支持动态模型列表获取和模型 ID 验证
+  - [`excluded_models.txt`](../excluded_models.txt) 文件可排除特定模型 ID
+
+- **🆕 脚本注入功能 v3.0**:
+  - 使用 Playwright 原生网络拦截，100% 可靠性
+  - 直接从油猴脚本解析模型数据，无需配置文件维护
+  - 前后端模型数据完全同步，注入模型标记为 `"injected": true`
+  - 详见 [脚本注入指南](script_injection_guide.md)
+
+### 客户端管理历史
+
+**客户端管理历史，代理不支持 UI 内编辑**: 客户端负责维护完整的聊天记录并将其发送给代理。代理服务器本身不支持在 AI Studio 界面中对历史消息进行编辑或分叉操作；它总是处理客户端发送的完整消息列表，然后将其发送到 AI Studio 页面。
+
+## 兼容性说明
+
+### Python 版本兼容性
+
+- **推荐版本**: Python 3.10+ 或 3.11+ (生产环境推荐)
+- **最低要求**: Python 3.9 (所有功能完全支持)
+- **Docker 环境**: Python 3.10 (容器内默认版本)
+- **完全支持**: Python 3.9, 3.10, 3.11, 3.12, 3.13
+- **依赖管理**: 使用 Poetry 管理，确保版本一致性
+
+### API 兼容性
+
+- **OpenAI API**: 完全兼容 OpenAI v1 API 标准，支持所有主流客户端
+- **FastAPI**: 基于 0.115.12 版本，包含最新性能优化和功能增强
+- **HTTP 协议**: 支持 HTTP/1.1 和 HTTP/2，完整的异步处理
+- **认证方式**: 支持 Bearer Token 和 X-API-Key 头部认证，OpenAI 标准兼容
+- **流式响应**: 完整支持 Server-Sent Events (SSE) 流式输出
+- **FastAPI**: 基于 0.111.0 版本，支持现代异步特性
+- **HTTP 协议**: 支持 HTTP/1.1 和 HTTP/2
+- **认证方式**: 支持 Bearer Token 和 X-API-Key 头部认证

+# 首次运行与认证设置指南
+
+为了避免每次启动都手动登录 AI Studio，你需要先通过 [`launch_camoufox.py --debug`](../launch_camoufox.py) 模式或 [`gui_launcher.py`](../gui_launcher.py) 的有头模式运行一次来生成认证文件。
+
+## 认证文件的重要性
+
+**认证文件是无头模式的关键**: 无头模式依赖于 `auth_profiles/active/` 目录下的有效 `.json` 文件来维持登录状态和访问权限。**文件可能会过期**，需要定期通过 [`launch_camoufox.py --debug`](../launch_camoufox.py) 模式手动运行、登录并保存新的认证文件来替换更新。
+
+## 方法一：通过命令行运行 Debug 模式
+
+**推荐使用 .env 配置方式**:
+```env
+# .env 文件配置
+DEFAULT_FASTAPI_PORT=2048
+STREAM_PORT=0
+LAUNCH_MODE=normal
+DEBUG_LOGS_ENABLED=true
+```
+
+```bash
+# 简化启动命令 (推荐)
+python launch_camoufox.py --debug
+
+# 传统命令行方式 (仍然支持)
+python launch_camoufox.py --debug --server-port 2048 --stream-port 0 --helper '' --internal-camoufox-proxy ''
+```
+
+**重要参数说明:**
+*   `--debug`: 启动有头模式，用于首次认证和调试
+*   `--server-port <端口号>`: 指定 FastAPI 服务器监听的端口 (默认: 2048)
+*   `--stream-port <端口号>`: 启动集成的流式代理服务端口 (默认: 3120)。设置为 `0` 可禁用此服务，首次启动建议禁用
+*   `--helper <端点URL>`: 指定外部 Helper 服务的地址。设置为空字符串 `''` 表示不使用外部 Helper
+*   `--internal-camoufox-proxy <代理地址>`: 为 Camoufox 浏览器指定代理。设置为空字符串 `''` 表示不使用代理
+*   **注意**: 如果需要启用流式代理服务，建议同时配置 `--internal-camoufox-proxy` 参数以确保正常运行
+
+### 操作步骤
+
+1. 脚本会启动 Camoufox（通过内部调用自身），并在终端输出启动信息。
+2. 你会看到一个 **带界面的 Firefox 浏览器窗口** 弹出。
+3. **关键交互:** **在弹出的浏览器窗口中完成 Google 登录**，直到看到 AI Studio 聊天界面。 (脚本会自动处理浏览器连接，无需用户手动操作)。
+4. **登录确认操作**: 当系统检测到登录页面并在终端显示类似以下提示时：
+   ```
+   检测到可能需要登录。如果浏览器显示登录页面，请在浏览器窗口中完成 Google 登录，然后在此处按 Enter 键继续...
+   ```
+   **用户必须在终端中按 Enter 键确认操作才能继续**。这个确认步骤是必需的，系统会等待用户的确认输入才会进行下一步的登录状态检查。
+5. 回到终端根据提示回车即可，如果设置使用非自动保存模式（即将弃用），请根据提示保存认证时输入 `y` 并回车 (文件名可默认)。文件会保存在 `auth_profiles/saved/`。
+6. **将 `auth_profiles/saved/` 下新生成的 `.json` 文件移动到 `auth_profiles/active/` 目录。** 确保 `active` 目录下只有一个 `.json` 文件。
+7. 可以按 `Ctrl+C` 停止 `--debug` 模式的运行。
+
+## 方法二：通过 GUI 启动有头模式
+
+1. 运行 `python gui_launcher.py`。
+2. 在 GUI 中输入 `FastAPI 服务端口` (默认为 2048)。
+3. 点击 `启动有头模式` 按钮。
+4. 在弹出的新控制台和浏览器窗口中，按照命令行方式的提示进行 Google 登录和认证文件保存操作。
+5. 同样需要手动将认证文件从 `auth_profiles/saved/` 移动到 `auth_profiles/active/`便于无头模式正常使用。
+
+## 激活认证文件
+
+1. 进入 `auth_profiles/saved/` 目录，找到刚才保存的 `.json` 认证文件。
+2. 将这个 `.json` 文件 **移动或复制** 到 `auth_profiles/active/` 目录下。
+3. **重要:** 确保 `auth_profiles/active/` 目录下 **有且仅有一个 `.json` 文件**。无头模式启动时会自动加载此目录下的第一个 `.json` 文件。
+
+## 认证文件过期处理
+
+**认证文件会过期!** Google 的登录状态不是永久有效的。当无头模式启动失败并报告认证错误或重定向到登录页时，意味着 `active` 目录下的认证文件已失效。你需要：
+
+1. 删除 `active` 目录下的旧文件。
+2. 重新执行上面的 **【通过命令行运行 Debug 模式】** 或 **【通过 GUI 启动有头模式】** 步骤，生成新的认证文件。
+3. 将新生成的 `.json` 文件再次移动到 `active` 目录下。
+
+## 重要提示
+
+*   **首次访问新主机的性能问题**: 当通过流式代理首次访问一个新的 HTTPS 主机时，服务需要为该主机动态生成并签署一个新的子证书。这个过程可能会比较耗时，导致对该新主机的首次连接请求响应较慢，甚至在某些情况下可能被主程序（如 [`server.py`](../server.py) 中的 Playwright 交互逻辑）误判为浏览器加载超时。一旦证书生成并缓存后，后续访问同一主机将会显著加快。

+
+完成首次认证设置后，您可以选择以下方式进行日常运行：
+
+- **图形界面启动**: 使用 [`gui_launcher.py`](../gui_launcher.py) 提供的现代化GUI界面
+- **命令行启动**: 直接使用 [`launch_camoufox.py`](../launch_camoufox.py) 命令行工具
+- **Docker部署**: 使用容器化部署方式
+
+## ⭐ 简化启动方式（推荐）
+
+**基于 `.env` 配置文件的统一配置管理，启动变得极其简单！**
+
+### 配置优势
+
+- ✅ **一次配置，终身受益**: 配置好 `.env` 文件后，启动命令极其简洁
+- ✅ **版本更新无忧**: `git pull` 后无需重新配置，直接启动
+- ✅ **参数集中管理**: 所有配置项统一在 `.env` 文件中
+- ✅ **环境隔离**: 不同环境可使用不同的配置文件

+*   **为什么使用?** 与标准的无头模式相比，虚拟显示模式通过创建一个完整的虚拟 X 服务器环境 (Xvfb) 来运行浏览器。这可以模拟一个更真实的桌面环境，从而可能进一步降低被网站检测为自动化脚本或机器人的风险，特别适用于对反指纹和反检测有更高要求的场景，同时确保无桌面的环境下能正常运行服务
+*   **什么时候使用?** 当您在 Linux 环境下运行，并且希望以无头模式操作。
+*   **如何使用?**
+    1. 确保您的 Linux 系统已安装 `xvfb` (参见 [安装指南](installation-guide.md) 中的安装说明)。
+    2. 在运行 [`launch_camoufox.py`](../launch_camoufox.py) 时添加 `--virtual-display` 标志。例如:
+        ```bash
+        python launch_camoufox.py --virtual-display --server-port 2048 --stream-port 3120 --internal-camoufox-proxy ''
+        ```
+
+## 代理配置优先级
+
+项目采用统一的代理配置管理系统，按以下优先级顺序确定代理设置：
+
+1. **`--internal-camoufox-proxy` 命令行参数** (最高优先级)
+   - 明确指定代理：`--internal-camoufox-proxy 'http://127.0.0.1:7890'`
+   - 明确禁用代理：`--internal-camoufox-proxy ''`
+2. **`UNIFIED_PROXY_CONFIG` 环境变量** (推荐，.env 文件配置)
+3. **`HTTP_PROXY` 环境变量**
+4. **`HTTPS_PROXY` 环境变量**
+5. **系统代理设置** (Linux 下的 gsettings，最低优先级)
+
+**推荐配置方式**:
+```env
+# .env 文件中统一配置代理
+UNIFIED_PROXY_CONFIG=http://127.0.0.1:7890
+# 或禁用代理
+UNIFIED_PROXY_CONFIG=
+```
+
+**重要说明**：此代理配置会同时应用于 Camoufox 浏览器和流式代理服务的上游连接，确保整个系统的代理行为一致。
+
+## 三层响应获取机制配置
+
+项目采用三层响应获取机制，确保高可用性和最佳性能。详细说明请参见 [流式处理模式详解](streaming-modes.md)。
+
+### 模式1: 优先使用集成的流式代理 (默认推荐)
+
+**使用 `.env` 配置（推荐）:**
+
+```env
+# 在 .env 文件中配置
+STREAM_PORT=3120
+UNIFIED_PROXY_CONFIG=http://127.0.0.1:7890  # 如需代理
+```
+
+```bash
+# 然后简单启动
+python launch_camoufox.py --headless
+```
+
+**命令行覆盖（高级用户）:**
+
+```bash
+# 使用自定义流式代理端口
+python launch_camoufox.py --headless --stream-port 3125
+
+# 启用代理配置
+python launch_camoufox.py --headless --internal-camoufox-proxy 'http://127.0.0.1:7890'
+
+# 明确禁用代理（覆盖 .env 中的设置）
+python launch_camoufox.py --headless --internal-camoufox-proxy ''
+```
+
+在此模式下，主服务器会优先尝试通过端口 `3120` (或 `.env` 中配置的 `STREAM_PORT`) 上的集成流式代理获取响应。如果失败，则回退到 Playwright 页面交互。
+
+### 模式2: 优先使用外部 Helper 服务 (禁用集成流式代理)
+
+**使用 `.env` 配置（推荐）:**
+
+```bash
+# 在 .env 文件中配置
+STREAM_PORT=0  # 禁用集成流式代理
+GUI_DEFAULT_HELPER_ENDPOINT=http://your-helper-service.com/api/getStreamResponse
+
+# 然后简单启动
+python launch_camoufox.py --headless
+```
+
+**命令行覆盖（高级用户）:**
+
+```bash
+# 外部Helper模式
+python launch_camoufox.py --headless --stream-port 0 --helper 'http://your-helper-service.com/api/getStreamResponse'
+```
+
+在此模式下，主服务器会优先尝试通过 Helper 端点获取响应 (需要有效的 `auth_profiles/active/*.json` 以提取 `SAPISID`)。如果失败，则回退到 Playwright 页面交互。
+
+### 模式3: 仅使用 Playwright 页面交互 (禁用所有流式代理和 Helper)
+
+**使用 `.env` 配置（推荐）:**
+
+```bash
+# 在 .env 文件中配置
+STREAM_PORT=0  # 禁用集成流式代理
+GUI_DEFAULT_HELPER_ENDPOINT=  # 禁用 Helper 服务
+
+# 然后简单启动
+python launch_camoufox.py --headless
+```
+
+**命令行覆盖（高级用户）:**
+
+```bash
+# 纯Playwright模式
+python launch_camoufox.py --headless --stream-port 0 --helper ''
+```
+
+在此模式下，主服务器将仅通过 Playwright 与 AI Studio 页面交互 (模拟点击"编辑"或"复制"按钮) 来获取响应。这是传统的后备方法。
+
+## 使用图形界面启动器
+
+项目提供了一个基于 Tkinter 的图形用户界面 (GUI) 启动器：[`gui_launcher.py`](../gui_launcher.py)。
+
+### 启动 GUI
+
+```bash
+python gui_launcher.py
+```
+
+### GUI 功能
+
+*   **服务端口配置**: 指定 FastAPI 服务器监听的端口号 (默认为 2048)。
+*   **端口进程管理**: 查询和停止指定端口上的进程。
+*   **启动选项**:
+    1. **启动有头模式 (Debug, 交互式)**: 对应 `python launch_camoufox.py --debug`
+    2. **启动无头模式 (后台独立运行)**: 对应 `python launch_camoufox.py --headless`
+*   **本地LLM模拟服务**: 启动和管理本地LLM模拟服务 (基于 [`llm.py`](../llm.py))
+*   **状态与日志**: 显示服务状态和实时日志
+
+### 使用建议
+
+*   首次运行或需要更新认证文件：使用"启动有头模式"
+*   日常后台运行：使用"启动无头模式"
+*   需要详细日志或调试：直接使用命令行 [`launch_camoufox.py`](../launch_camoufox.py)
+
+## 重要注意事项
+
+### 配置优先级
+
+1. **`.env` 文件配置** - 推荐的配置方式，一次设置长期使用
+2. **命令行参数** - 可以覆盖 `.env` 文件中的设置，适用于临时调整
+3. **环境变量** - 最低优先级，主要用于系统级配置
+
+### 使用建议
+
+- **日常使用**: 配置好 `.env` 文件后，使用简单的 `python launch_camoufox.py --headless` 即可
+- **临时调整**: 需要临时修改配置时，使用命令行参数覆盖，无需修改 `.env` 文件
+- **首次设置**: 使用 `python launch_camoufox.py --debug` 进行认证设置
+
+**只有当你确认使用调试模式一切运行正常（特别是浏览器内的登录和认证保存），并且 `auth_profiles/active/` 目录下有有效的认证文件后，才推荐使用无头模式作为日常后台运行的标准方式。**
+
+## 下一步
+
+日常运行设置完成后，请参考：

+## 🔧 依赖管理 (Poetry)
+
+### Poetry 基础命令
+
+```bash
+# 查看项目信息
+poetry show
+
+# 查看依赖树
+poetry show --tree
+
+# 添加新依赖
+poetry add package_name
+
+# 添加开发依赖
+poetry add --group dev package_name
+
+# 移除依赖
+poetry remove package_name
+
+# 更新依赖
+poetry update
+
+# 更新特定依赖
+poetry update package_name
+
+# 导出 requirements.txt (兼容性)
+poetry export -f requirements.txt --output requirements.txt
+```
+
+### 依赖分组
+
+项目使用 Poetry 的依赖分组功能：
+
+```toml
+[tool.poetry.dependencies]
+# 生产依赖
+python = ">=3.9,<4.0"
+fastapi = "==0.115.12"
+# ... 其他生产依赖
+
+[tool.poetry.group.dev.dependencies]
+# 开发依赖 (可选安装)
+pytest = "^7.0.0"
+black = "^23.0.0"
+isort = "^5.12.0"
+```
+
+### 虚拟环境管理
+
+```bash
+# 查看虚拟环境信息
+poetry env info
+
+# 查看虚拟环境路径
+poetry env info --path
+
+# 激活虚拟环境
+poetry env activate
+
+# 在虚拟环境中运行命令
+poetry run python script.py
+
+# 删除虚拟环境
+poetry env remove python
+```
+
+## 🔍 类型检查 (Pyright)
+
+### Pyright 配置
+
+项目使用 `pyrightconfig.json` 进行类型检查配置：
+
+```json
+{
+    "pythonVersion": "3.13",
+    "pythonPlatform": "Darwin",
+    "typeCheckingMode": "off",
+    "extraPaths": [
+        "./api_utils",
+        "./browser_utils",
+        "./config",
+        "./models",
+        "./logging_utils",
+        "./stream"
+    ]
+}
+```
+
+### 使用 Pyright
+
+```bash
+# 安装 Pyright
+npm install -g pyright
+
+# 检查整个项目
+pyright
+
+# 检查特定文件
+pyright api_utils/app.py
+
+# 监视模式 (文件变化时自动检查)
+pyright --watch
+```
+
+### 类型注解最佳实践
+
+```python
+from typing import Optional, List, Dict, Any
+from pydantic import BaseModel
+
+# 函数类型注解
+def process_request(data: Dict[str, Any]) -> Optional[str]:
+    """处理请求数据"""
+    return data.get("message")
+
+# 类型别名
+ModelConfig = Dict[str, Any]
+ResponseData = Dict[str, str]
+
+# Pydantic 模型
+class ChatRequest(BaseModel):
+    message: str
+    model: Optional[str] = None
+    temperature: float = 0.7
+```

+# 环境变量配置指南
+
+本文档详细介绍如何使用 `.env` 文件来配置 AI Studio Proxy API 项目，实现统一的配置管理。
+
+## 概述
+
+项目采用基于 `.env` 文件的现代化配置管理系统，提供以下优势：
+
+### 主要优势
+
+- ✅ **版本更新无忧**: 一个 `git pull` 就完成更新，无需重新配置
+- ✅ **配置集中管理**: 所有配置项统一在 `.env` 文件中，清晰明了
+- ✅ **启动命令简化**: 无需复杂的命令行参数，一键启动
+- ✅ **安全性**: `.env` 文件已被 `.gitignore` 忽略，不会泄露敏感配置
+- ✅ **灵活性**: 支持不同环境的配置管理（开发、测试、生产）
+- ✅ **Docker 兼容**: Docker 和本地环境使用相同的配置方式
+- ✅ **模块化设计**: 配置项按功能分组，便于理解和维护
+
+## 快速开始
+
+### 1. 复制配置模板
+
+```bash
+cp .env.example .env
+```
+
+### 2. 编辑配置文件
+
+根据您的需要修改 `.env` 文件中的配置项：
+
+```bash
+# 编辑配置文件
+nano .env
+# 或使用其他编辑器
+code .env
+```
+
+### 3. 启动服务
+
+配置完成后，启动变得非常简单：
+
+```bash
+# 图形界面启动（推荐新手）
+python gui_launcher.py
+
+# 命令行启动（推荐日常使用）
+python launch_camoufox.py --headless
+
+# 调试模式（首次设置或故障排除）
+python launch_camoufox.py --debug
+```
+
+**就这么简单！** 无需复杂的命令行参数，所有配置都在 `.env` 文件中预设好了。
+
+## 启动命令对比
+
+### 使用 `.env` 配置前（复杂）
+
+```bash
+# 之前需要这样的复杂命令
+python launch_camoufox.py --headless --server-port 2048 --stream-port 3120 --helper '' --internal-camoufox-proxy 'http://127.0.0.1:7890'
+```
+
+### 使用 `.env` 配置后（简单）
+
+```bash
+# 现在只需要这样
+python launch_camoufox.py --headless
+```
+
+**配置一次，终身受益！** 所有复杂的参数都在 `.env` 文件中预设，启动命令变得极其简洁。

+
+## 配置优先级
+
+配置项的优先级顺序（从高到低）：
+
+1. **命令行参数** - 直接传递给程序的参数
+2. **环境变量** - 系统环境变量或 `.env` 文件中的变量
+3. **默认值** - 代码中定义的默认值
+
+## 常见配置场景
+
+### 场景 1：使用代理
+
+```env
+# 启用代理
+HTTP_PROXY=http://127.0.0.1:7890
+HTTPS_PROXY=http://127.0.0.1:7890
+
+# GUI 中也使用相同代理
+GUI_DEFAULT_PROXY_ADDRESS=http://127.0.0.1:7890
+```
+
+### 场景 2：调试模式
+
+```env
+# 启用详细日志
+DEBUG_LOGS_ENABLED=true
+TRACE_LOGS_ENABLED=true
+SERVER_LOG_LEVEL=DEBUG
+SERVER_REDIRECT_PRINT=true
+```
+
+### 场景 3：生产环境
+
+```env
+# 生产环境配置
+SERVER_LOG_LEVEL=WARNING
+DEBUG_LOGS_ENABLED=false
+TRACE_LOGS_ENABLED=false
+
+# 更长的超时时间
+RESPONSE_COMPLETION_TIMEOUT=600000
+SILENCE_TIMEOUT_MS=120000
+```
+
+### 场景 4：自定义端口
+
+```env
+# 避免端口冲突
+DEFAULT_FASTAPI_PORT=3048
+DEFAULT_CAMOUFOX_PORT=9223
+STREAM_PORT=3121
+```
+
+### 场景 5：启用脚本注入 v3.0 🆕
+
+```env
+# 启用脚本注入功能 v3.0
+ENABLE_SCRIPT_INJECTION=true
+
+# 使用自定义脚本（模型数据直接从脚本解析）
+USERSCRIPT_PATH=browser_utils/my_custom_script.js
+
+# 调试模式查看注入效果
+DEBUG_LOGS_ENABLED=true
+
+# 流式代理配置（与脚本注入配合使用）
+STREAM_PORT=3120
+```
+
+**v3.0 脚本注入优势**：
+- 使用 Playwright 原生网络拦截，无时序问题
+- 前后端模型数据100%同步
+- 零配置维护，脚本更新自动生效
+
+## 配置优先级
+
+项目采用分层配置系统，按以下优先级顺序确定最终配置：
+
+1. **命令行参数** (最高优先级)
+   ```bash
+   # 命令行参数会覆盖 .env 文件中的设置
+   python launch_camoufox.py --headless --server-port 3048
+   ```
+
+2. **`.env` 文件配置** (推荐)
+   ```env
+   # .env 文件中的配置
+   DEFAULT_FASTAPI_PORT=2048
+   ```
+
+3. **系统环境变量** (最低优先级)
+   ```bash
+   # 系统环境变量
+   export DEFAULT_FASTAPI_PORT=2048
+   ```
+
+### 使用建议
+
+- **日常使用**: 在 `.env` 文件中配置所有常用设置
+- **临时调整**: 使用命令行参数进行临时覆盖，无需修改 `.env` 文件
+- **CI/CD 环境**: 可以通过系统环境变量进行配置
+
+## 注意事项
+
+### 1. 文件安全
+
+- `.env` 文件已被 `.gitignore` 忽略，不会被提交到版本控制
+- 请勿在 `.env.example` 中包含真实的敏感信息
+- 如需分享配置，请复制并清理敏感信息后再分享
+
+### 2. 格式要求
+
+- 环境变量名区分大小写
+- 布尔值使用 `true`/`false`
+- 数组使用 JSON 格式：`["item1", "item2"]`
+- 字符串值如包含特殊字符，请使用引号
+
+### 3. 重启生效
+
+修改 `.env` 文件后需要重启服务才能生效。
+
+### 4. 验证配置
+
+启动服务时，日志会显示加载的配置信息，可以通过日志验证配置是否正确。
+
+## 故障排除
+
+### 配置未生效
+
+1. 检查 `.env` 文件是否在项目根目录
+2. 检查环境变量名是否正确（区分大小写）
+3. 检查值的格式是否正确
+4. 重启服务
+
+### 代理配置问题
+
+1. 确认代理服务器地址和端口正确
+2. 检查代理服务器是否正常运行
+3. 验证网络连接
+
+### 端口冲突
+
+1. 检查端口是否被其他程序占用
+2. 使用 GUI 启动器的端口检查功能
+3. 修改为其他可用端口
