pip is the `package installer`_ for Python. You can use pip to install packages from the `Python Package Index`_ and other indexes.
|
| 41 |
+
|
| 42 |
+
Please take a look at our documentation for how to install and use pip:
|
| 43 |
+
|
| 44 |
+
* `Installation`_
|
| 45 |
+
* `Usage`_
|
| 46 |
+
|
| 47 |
+
We release updates regularly, with a new version every 3 months. Find more details in our documentation:
|
| 48 |
+
|
| 49 |
+
* `Release notes`_
|
| 50 |
+
* `Release process`_
|
| 51 |
+
|
| 52 |
+
In pip 20.3, we've `made a big improvement to the heart of pip`_; `learn more`_. We want your input, so `sign up for our user experience research studies`_ to help us do it right.
|
| 53 |
+
|
| 54 |
+
**Note**: pip 21.0, in January 2021, removed Python 2 support, per pip's `Python 2 support policy`_. Please migrate to Python 3.
|
| 55 |
+
|
| 56 |
+
If you find bugs, need help, or want to talk to the developers, please use our mailing lists or chat rooms:
|
| 57 |
+
|
| 58 |
+
* `Issue tracking`_
|
| 59 |
+
* `Discourse channel`_
|
| 60 |
+
* `User IRC`_
|
| 61 |
+
|
| 62 |
+
If you want to get involved head over to GitHub to get the source code, look at our development documentation and feel free to jump on the developer mailing lists and chat rooms:

An exponential backoff strategy used to mediate contention between multiple

Each retry occurs at a random time in a geometrically expanding interval.

Getter method to remove any trailing dots that indicate the hostname is an FQDN.
|
| 136 |
+
|
| 137 |
+
In general, SSL certificates don't include the trailing dot indicating a
|
| 138 |
+
fully-qualified domain name, and thus, they don't validate properly when
|
| 139 |

checked against a domain name that includes the dot. In addition, some

+
servers may not expect to receive the trailing dot when provided.
|
| 141 |
+
|
| 142 |

However, the hostname with trailing dot is critical to DNS resolution; doing a
|
| 143 |
+
lookup with the trailing dot will properly only resolve the appropriate FQDN,
|
| 144 |
+
whereas a lookup without a trailing dot will search the system's search domain
|
| 145 |
+
list. Thus, it's important to keep the original host around for use only in
|
| 146 |
+
those cases where it's appropriate (i.e., when doing DNS lookup to establish the
|
| 147 |
+
actual TCP connection across which we're going to send HTTP requests).

Socket timeout in seconds for each individual connection. This can

be a float or integer, which sets the timeout for the HTTP request,

| 135 |

or an instance of :class:`urllib3.util.Timeout` which gives you more

Number of connections to save that can be reused. More than 1 is useful

been used.

If set to True, no more than ``maxsize`` connections will be used at
|
| 147 |

a time. When no free connections are available, the call will block
|
| 148 |
+
until a connection has been released. This is a useful side effect for
|
| 149 |
+
particular multithreaded situations where one does not want to use more

than maxsize connections per host to prevent flooding.

Data to send in the request body, either :class:`str`, :class:`bytes`,

:param retries:
|

Configure the number of retries to allow before raising a
|
| 583 |
+
:class:`~urllib3.exceptions.MaxRetryError` exception.
|
| 584 |
+
|
| 585 |
+
Pass ``None`` to retry until you receive a response. Pass a
|
| 586 |
+
:class:`~urllib3.util.retry.Retry` object for fine-grained control
|
| 587 |
+
over different types of retries.
|
| 588 |
+
Pass an integer number to retry connection errors that many times,
|
| 589 |
+
but no other types of errors. Pass zero to never retry.
|
| 590 |
+
|
| 591 |
+
If ``False``, then retries are disabled and any exception is raised
|
| 592 |
+
immediately. Also, instead of raising a MaxRetryError on redirects,
|
| 593 |
+
the redirect response will be returned.
|
| 594 |

:type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
|
| 596 |

|
| 598 |
+
If True, automatically handle redirects (status codes 301, 302,
|
| 599 |
+
303, 307, 308). Each redirect counts as a retry. Disabling retries
|

will disable redirect, too.

+
:param assert_same_host:
|
| 603 |
+
If ``True``, will make sure that the host of the pool requests is
|
| 604 |
+
consistent else will raise HostChangedError. When ``False``, you can
|
| 605 |
+
use the pool on an HTTP proxy and request foreign hosts.
|
| 606 |
+
|
| 607 |
+
:param timeout:
|
| 608 |
+
If specified, overrides the default timeout for this one
|
| 609 |
+
request. It may be a float (in seconds) or an instance of

| 610 |
+
:class:`urllib3.util.Timeout`.
|
| 611 |
+
|
| 612 |
+
:param pool_timeout:
|
| 613 |
+
If set and the pool is set to block=True, then this method will
|
| 614 |
+
block for ``pool_timeout`` seconds and raise EmptyPoolError if no
|
| 615 |
+
connection is available within the time period.
|
| 616 |
+
|
| 617 |
+
:param release_conn:
|
| 618 |
+
If False, then the urlopen call will not release the connection
|
| 619 |
+
back into the pool once a response is received (but will release if
|
| 620 |
+
you read the entire contents of the response such as when
|
| 621 |
+
`preload_content=True`). This is useful if you're not preloading
|
| 622 |
+
the response's content immediately. You will need to call
|
| 623 |
+
``r.release_conn()`` on the response ``r`` to return the connection
|
| 624 |
+
back into the pool. If None, it takes the value of
|
| 625 |
+
``response_kw.get('preload_content', True)``.
|
| 626 |
+
|
| 627 |
+
:param chunked:
|
| 628 |
+
If True, urllib3 will send the body using chunked transfer
|
| 629 |

encoding. Otherwise, urllib3 will send the body using the standard

| 630 |
+
content-length form. Defaults to False.

:param int body_pos:
|
| 633 |
+
Position to seek to in file-like body in the event of a retry or

redirect. Typically this won't need to be set because urllib3 will
|
| 635 |
+
auto-populate the value when needed.

This module uses ctypes to bind a whole bunch of functions and constants from
|
| 3 |
+
SecureTransport. The goal here is to provide the low-level API to
|
| 4 |
+
SecureTransport. These are essentially the C-level functions and constants, and
|
| 5 |
+
they're pretty gross to work with.

This module provides a pool manager that uses Google App Engine's
|
| 3 |
+
`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
|
| 4 |
+
|
| 5 |
+
Example usage::
|
| 6 |
+
|
| 7 |
+
from pip._vendor.urllib3 import PoolManager
|
| 8 |
+
from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
|
| 9 |
+
|
| 10 |
+
if is_appengine_sandbox():
|
| 11 |
+
# AppEngineManager uses AppEngine's URLFetch API behind the scenes
|
| 12 |
+
http = AppEngineManager()
|
| 13 |
+
else:
|
| 14 |
+
# PoolManager uses a socket-level API behind the scenes
|
| 15 |
+
http = PoolManager()
|
| 16 |
+
|
| 17 |
+
r = http.request('GET', 'https://google.com/')
|
| 18 |
+
|
| 19 |
+
There are `limitations <https://cloud.google.com/appengine/docs/python/\
|
| 20 |
+
urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
|
| 21 |
+
the best choice for your application. There are three options for using
|
| 22 |
+
urllib3 on Google App Engine:
|
| 23 |
+
|
| 24 |
+
1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
|
| 25 |
+
cost-effective in many circumstances as long as your usage is within the
|
| 26 |
+
limitations.
|
| 27 |
+
2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
|
| 28 |
+
Sockets also have `limitations and restrictions
|
| 29 |
+
<https://cloud.google.com/appengine/docs/python/sockets/\
|
| 30 |
+
#limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
|
| 31 |
+
To use sockets, be sure to specify the following in your ``app.yaml``::
|
| 32 |
+
|
| 33 |
+
env_variables:
|
| 34 |
+
GAE_USE_SOCKETS_HTTPLIB : 'true'
|
| 35 |
+
|
| 36 |
+
3. If you are using `App Engine Flexible
|
| 37 |
+
<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
|
| 38 |
+
:class:`PoolManager` without any configuration or special environment variables.

+
TLS with SNI_-support for Python 2. Follow these instructions if you would
|
| 3 |
+
like to verify TLS certificates in Python 2. Note, the default libraries do
|
| 4 |
+
*not* do certificate checking; you need to do additional work to validate
|
| 5 |
+
certificates yourself.
|
| 6 |
+
|
| 7 |
+
This needs the following packages installed:
|
| 8 |
+
|
| 9 |
+
* `pyOpenSSL`_ (tested with 16.0.0)
|
| 10 |
+
* `cryptography`_ (minimum 1.3.4, from pyopenssl)
|
| 11 |
+
* `idna`_ (minimum 2.0, from cryptography)
|
| 12 |
+
|
| 13 |
+
However, pyopenssl depends on cryptography, which depends on idna, so while we
|
| 14 |
+
use all three directly here we end up having relatively few packages required.
|
| 15 |
+
|
| 16 |
+
You can install them with the following command:
|
| 17 |
+
|
| 18 |
+
.. code-block:: bash
|
| 19 |
+
|
| 20 |
+
$ python -m pip install pyopenssl cryptography idna
|
| 21 |
+
|
| 22 |
+
To activate certificate checking, call
|
| 23 |
+
:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
|
| 24 |
+
before you begin making HTTP requests. This can be done in a ``sitecustomize``
|
| 25 |
+
module, or at any other time before your application begins using ``urllib3``,
|
| 26 |
+
like this:
|
| 27 |
+
|
| 28 |
+
.. code-block:: python
|
| 29 |
+
|
| 30 |
+
try:
|
| 31 |
+
import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl
|
| 32 |
+
pyopenssl.inject_into_urllib3()
|
| 33 |
+
except ImportError:
|
| 34 |
+
pass
|
| 35 |
+
|
| 36 |
+
Now you can use :mod:`urllib3` as you normally would, and it will support SNI
|
| 37 |
+
when the required modules are installed.
|
| 38 |
+
|
| 39 |
+
Activating this module also has the positive side effect of disabling SSL/TLS
|
| 40 |
+
compression in Python 2 (see `CRIME attack`_).

SecureTranport support for urllib3 via ctypes.
|
| 3 |
+
|
| 4 |
+
This makes platform-native TLS available to urllib3 users on macOS without the
|
| 5 |
+
use of a compiler. This is an important feature because the Python Package
|
| 6 |
+
Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
|
| 7 |
+
that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
|
| 8 |
+
this is to give macOS users an alternative solution to the problem, and that
|
| 9 |
+
solution is to use SecureTransport.
|
| 10 |
+
|
| 11 |
+
We use ctypes here because this solution must not require a compiler. That's
|
| 12 |
+
because pip is not allowed to require a compiler either.
|
| 13 |
+
|
| 14 |
+
This is not intended to be a seriously long-term solution to this problem.
|
| 15 |
+
The hope is that PEP 543 will eventually solve this issue for us, at which
|
| 16 |
+
point we can retire this contrib module. But in the short term, we need to
|
| 17 |
+
solve the impending tire fire that is Python on Mac without this kind of
|
| 18 |
+
contrib module. So...here we are.
|
| 19 |
+
|
| 20 |
+
To use this module, simply import and inject it::
|
| 21 |
+
|
| 22 |
+
import pip._vendor.urllib3.contrib.securetransport as securetransport
|
| 23 |
+
securetransport.inject_into_urllib3()
|
| 24 |
+
|
| 25 |
+
Happy TLSing!

This module contains provisional support for SOCKS proxies from within
|
| 4 |
+
urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
|
| 5 |
+
SOCKS5. To enable its functionality, either install PySocks or install this
|
| 6 |
+
module with the ``socks`` extra.
|
| 7 |
+
|
| 8 |
+
The SOCKS implementation supports the full range of urllib3 features. It also
|
| 9 |
+
supports the following SOCKS features:
|
| 10 |
+
|
| 11 |
+
- SOCKS4A (``proxy_url='socks4a://...``)
|
| 12 |
+
- SOCKS4 (``proxy_url='socks4://...``)
|
| 13 |
+
- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
|
| 14 |
+
- SOCKS5 with local DNS (``proxy_url='socks5://...``)
|
| 15 |
+
- Usernames and passwords for the SOCKS proxy
|
| 16 |
+
|
| 17 |
+
.. note::
|
| 18 |
+
It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
|
| 19 |
+
your ``proxy_url`` to ensure that DNS resolution is done from the remote
|
| 20 |
+
server instead of client-side when connecting to a domain name.
|
| 21 |
+
|
| 22 |
+
SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
|
| 23 |
+
supports IPv4, IPv6, and domain names.
|
| 24 |
+
|
| 25 |
+
When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
|
| 26 |
+
will be sent as the ``userid`` section of the SOCKS request:
|
| 27 |
+
|
| 28 |
+
.. code-block:: python
|
| 29 |
+
|
| 30 |
+
proxy_url="socks4a://<userid>@proxy-host"
|
| 31 |
+
|
| 32 |
+
When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
|
| 33 |
+
of the ``proxy_url`` will be sent as the username/password to authenticate
|
| 34 |
+
with the proxy:
|
| 35 |
+
|
| 36 |
+
.. code-block:: python
|
| 37 |
+
|
| 38 |
+
proxy_url="socks5h://<username>:<password>@proxy-host"
