:mod:`httplib` --- HTTP protocol client
=======================================
.. module:: httplib
:synopsis: HTTP and HTTPS protocol client (requires sockets).
Add renaming notices to 3.0 http package members.
2008-05-26 12:01:48 -03:00
.. note::
The :mod:`httplib` module has been renamed to :mod:`http.client` in Python
3.0. The :term:`2to3` tool will automatically adapt imports when converting
your sources to 3.0.

.. index::
pair: HTTP; protocol
single: HTTP; httplib (standard module)
.. index:: module: urllib
Backport source links from 3.x. Existing links have been updated to use the new reST role. In some files, I have also made cosmetic changes to the header.

2007-08-15 11:28:01 -03:00
This module defines classes which implement the client side of the HTTP and
HTTPS protocols. It is normally not used directly --- the module :mod:`urllib`
uses it to handle URLs that use HTTP and HTTPS.
.. note::
HTTPS support is only available if the :mod:`socket` module was compiled with
SSL support.
.. note::
The public interface for this module changed substantially in Python 2.0. The
:class:`HTTP` class is retained only for backward compatibility with 1.5.2. It
should not be used in new code. Refer to the online docstrings for usage.
The module provides the following classes:

number. If no port number is passed, the port is extracted from the host
string if it has the form ``host:port``, else the default HTTP port (80) is

be raised if the status line can't be parsed as a valid HTTP/1.0 or 1.1
status line. If the optional *timeout* parameter is given, blocking
operations (like connection attempts) will timeout after that many seconds
Fixed the semantic of timeout for socket.create_connection and all the upper level libraries that use it, including urllib2. Added and fixed some tests, and changed docs correspondingly. Thanks to John J Lee for the patch and the pusing, :)

2010-01-02 22:06:07 -04:00
The optional *source_address* parameter may be a tuple of a (host, port)
to use as the source address the HTTP connection is made from.

For example, the following calls all create instances that connect to the server
at the same host and port::
>>> h1 = httplib.HTTPConnection('www.cwi.nl')
>>> h2 = httplib.HTTPConnection('www.cwi.nl:80')
>>> h3 = httplib.HTTPConnection('www.cwi.nl', 80)
>>> h3 = httplib.HTTPConnection('www.cwi.nl', 80, timeout=10)

An :class:`HTTPMessage` instance is used to hold the headers from an HTTP
response. It is implemented using the :class:`mimetools.Message` class and
provides utility functions to deal with HTTP Headers. It is not directly

This dictionary maps the HTTP 1.1 status codes to the W3C names.
Example: ``httplib.responses[httplib.NOT_FOUND]`` is ``'Not Found'``.
.. versionadded:: 2.5
.. _httpconnection-objects:
HTTPConnection Objects
----------------------
:class:`HTTPConnection` instances have the following methods:
.. method:: HTTPConnection.request(method, url[, body[, headers]])
This will send a request to the server using the HTTP request method *method*
and the selector *url*. If the *body* argument is present, it should be a
string of data to send after the headers are finished. Alternatively, it may
be an open file object, in which case the contents of the file is sent; this
file object should support ``fileno()`` and ``read()`` methods. The header
Content-Length is automatically set to the correct value. The *headers*
argument should be a mapping of extra HTTP headers to send with the request.
.. versionchanged:: 2.6
*body* can be a file object.
.. method:: HTTPConnection.getresponse()
Should be called after a request is sent to get the response from the server.
Returns an :class:`HTTPResponse` instance.
.. note::
Note that you must have read the whole response before you can send a new
request to the server.
.. method:: HTTPConnection.set_debuglevel(level)
Set the debugging level (the amount of debugging output printed). The default
debug level is ``0``, meaning no debugging output is printed.
Document the headers parameter for set_tunnel.

.. method:: HTTPConnection.set_tunnel(host,port=None, headers=None)
Fixed Issue1424152, urllib2 fails with HTTPS over Proxy.
2009-05-24 06:14:50 -03:00
Set the host and the port for HTTP Connect Tunnelling. Normally used when
it is required to do HTTPS Conection through a proxy server.
Document the headers parameter for set_tunnel.
2009-12-20 03:29:31 -04:00
The headers argument should be a mapping of extra HTTP headers to to sent
with the CONNECT request.
add a versionadded tag for set_tunnel
2009-05-24 15:00:13 -03:00
.. versionadded:: 2.7
Fixed Issue1424152, urllib2 fails with HTTPS over Proxy.

.. method:: HTTPConnection.connect()
Connect to the server specified when the object was created.
.. method:: HTTPConnection.close()
Close the connection to the server.
As an alternative to using the :meth:`request` method described above, you can
also send your request step by step, by using the four functions below.
.. method:: HTTPConnection.putrequest(request, selector[, skip_host[, skip_accept_encoding]])
This should be the first call after the connection to the server has been made.
It sends a line to the server consisting of the *request* string, the *selector*
string, and the HTTP version (``HTTP/1.1``). To disable automatic sending of
``Host:`` or ``Accept-Encoding:`` headers (for example to accept additional
content encodings), specify *skip_host* or *skip_accept_encoding* with non-False
values.
.. versionchanged:: 2.4
*skip_accept_encoding* argument added.
.. method:: HTTPConnection.putheader(header, argument[, ...])
Send an :rfc:`822`\ -style header to the server. It sends a line to the server
consisting of the header, a colon and a space, and the first argument. If more
arguments are given, continuation lines are sent, each consisting of a tab and
an argument.
update 2.7 - Document message_body arg in HTTPConnection.endheaders
2011-10-02 20:37:58 -03:00
.. method:: HTTPConnection.endheaders(message_body=None)
Move the 2.6 reST doc tree in place.
2007-08-15 11:28:01 -03:00
Send a blank line to the server, signalling the end of the headers.
update 2.7 - Document message_body arg in HTTPConnection.endheaders
2011-10-02 20:37:58 -03:00
The optional message_body argument can be used to pass message body
associated with the request. The message body will be sent in
the same packet as the message headers if possible. The
message_body should be a string.

2007-08-15 11:28:01 -03:00
.. method:: HTTPConnection.send(data)
Send data to the server. This should be used directly only after the
:meth:`endheaders` method has been called and before :meth:`getresponse` is
called.

>>> conn = httplib.HTTPConnection("www.python.org")
>>> conn.request("GET", "/index.html")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
200 OK

>>> conn.request("GET", "/parrot.spam")
>>> r2 = conn.getresponse()
>>> print r2.status, r2.reason
