http.request

The http.request module encapsulates all the functionality required to retrieve an HTTP document from a server.

new_from_uri(uri) {#http.request.new_from_uri}

Creates a new http.request object from the given URI.

new_connect(uri, connect_authority) {#http.request.new_connect}

Creates a new http.request object from the given URI that will perform a CONNECT request.

request.host {#http.request.host}

The host this request should be sent to.

request.port {#http.request.port}

The port this request should be sent to.

request.bind {#http.request.bind}

The local outgoing address and optionally port to bind in the form of "address[:port]". Default is to allow the kernel to choose an address+port.

IPv6 addresses may be specified via square bracket notation. e.g. "127.0.0.1", "127.0.0.1:50000", "[::1]:30000".

This option is rarely needed. Supplying an address can be used to manually select the network interface to make the request from, while supplying a port is only really used to interoperate with firewalls or devices that demand use of a certain port.

request.tls {#http.request.tls}

A boolean indicating if TLS should be used.

request.ctx {#http.request.ctx}

An alternative SSL_CTX* to use. If not specified, uses the default TLS settings (see http.tls for information).

request.sendname {#http.request.sendname}

The TLS SNI host name used.

request.version {#http.request.version}

The HTTP version to use; leave as nil to auto-select.

request.proxy {#http.request.proxy}

Specifies the a proxy that the request will be made through. The value should be a URI or false to turn off proxying for the request.

request.headers {#http.request.headers}

A http.headers object of headers that will be sent in the request.

request.hsts {#http.request.hsts}

The http.hsts store that will be used to enforce HTTP strict transport security. An attempt will be made to add strict transport headers from a response to the store.

Defaults to a shared store.

request.proxies {#http.request.proxies}

The http.proxies object used to select a proxy for the request. Only consulted if request.proxy is nil.

request.cookie_store {#http.request.cookie_store}

The http.cookie.store that will be used to find cookies for the request. An attempt will be made to add cookies from a response to the store.

Defaults to a shared store.

request.is_top_level {#http.request.is_top_level}

A boolean flag indicating if this request is a "top level" request (See RFC 6265bis-02 Section 5.2)

Defaults to true

request.site_for_cookies {#http.request.site_for_cookies}

A string containing the host that should be considered as the "site for cookies" (See RFC 6265bis-02 Section 5.2), can be nil if unknown.

Defaults to nil.

request.follow_redirects {#http.request.follow_redirects}

Boolean indicating if :go() should follow redirects. Defaults to true.

request.expect_100_timeout {#http.request.expect_100_timeout}

Number of seconds to wait for a 100 Continue response before proceeding to send a request body. Defaults to 1.

request.max_redirects {#http.request.max_redirects}

Maximum number of redirects to follow before giving up. Defaults to 5. Set to math.huge to not give up.

request.post301 {#http.request.post301}

Respect RFC 2616 Section 10.3.2 and don't convert POST requests into body-less GET requests when following a 301 redirect. The non-RFC behaviour is ubiquitous in web browsers and assumed by servers. Modern HTTP endpoints send status code 308 to indicate that they don't want the method to be changed. Defaults to false.

request.post302 {#http.request.post302}

Respect RFC 2616 Section 10.3.3 and don't convert POST requests into body-less GET requests when following a 302 redirect. The non-RFC behaviour is ubiquitous in web browsers and assumed by servers. Modern HTTP endpoints send status code 307 to indicate that they don't want the method to be changed. Defaults to false.

request:clone() {#http.request:clone}

Creates and returns a clone of the request.

The clone has its own deep copies of the .headers and .h2_settings fields.

The .tls and .body fields are shallow copied from the original request.

request:handle_redirect(headers) {#http.request:handle_redirect}

Process a redirect.

headers should be response headers for a redirect.

Returns a new request object that will fetch from new location.

request:to_uri(with_userinfo) {#http.request:to_uri}

Returns a URI for the request.

If with_userinfo is true and the request has an authorization header (or proxy-authorization for a CONNECT request), the returned URI will contain a userinfo component.

request:set_body(body) {#http.request:set_body}

Allows setting a request body. body may be a string, function or lua file object.

  • If body is a string it will be sent as given.
  • If body is a function, it will be called repeatedly like an iterator. It should return chunks of the request body as a string or nil if done.
  • If body is a lua file object, it will be :seek'd to the start, then sent as a body. Any errors encountered during file operations will be thrown.

request:go(timeout) {#http.request:timeout}

Performs the request.

The request object is not invalidated; and can be reused for a new request. On success, returns the response headers and a stream.
