:mod:`httplib` --- HTTP protocol client

=======================================

.. module:: httplib

   :synopsis: HTTP and HTTPS protocol client (requires sockets).

.. 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

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:

.. class:: HTTPConnection(host[, port[, strict[, timeout]]])

   An :class:`HTTPConnection` instance represents one transaction with an HTTP

   server.  It should be instantiated passing it a host and optional port

   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

   used.  When True, the optional parameter *strict* causes ``BadStatusLine`` to

   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

   (if it is not given, the global default timeout setting is used).

   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)

   .. versionadded:: 2.0

   .. versionchanged:: 2.6

      *timeout* was added.

.. class:: HTTPSConnection(host[, port[, key_file[, cert_file[, strict[, timeout]]]]])

   A subclass of :class:`HTTPConnection` that uses SSL for communication with

   secure servers.  Default port is ``443``. *key_file* is the name of a PEM

   formatted file that contains your private key. *cert_file* is a PEM formatted

   certificate chain file.

   .. warning::

      This does not do any certificate verification!

   .. versionadded:: 2.0

   .. versionchanged:: 2.6

      *timeout* was added.

.. class:: HTTPResponse(sock[, debuglevel=0][, strict=0])

   Class whose instances are returned upon successful connection.  Not instantiated

   directly by user.

   .. versionadded:: 2.0

The following exceptions are raised as appropriate:

.. exception:: HTTPException

   The base class of the other exceptions in this module.  It is a subclass of

   :exc:`Exception`.

   .. versionadded:: 2.0

.. exception:: NotConnected

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: InvalidURL

   A subclass of :exc:`HTTPException`, raised if a port is given and is either

   non-numeric or empty.

   .. versionadded:: 2.3

.. exception:: UnknownProtocol

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: UnknownTransferEncoding

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: UnimplementedFileMode

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: IncompleteRead

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: ImproperConnectionState

   A subclass of :exc:`HTTPException`.

   .. versionadded:: 2.0

.. exception:: CannotSendRequest

   A subclass of :exc:`ImproperConnectionState`.

   .. versionadded:: 2.0

.. exception:: CannotSendHeader

   A subclass of :exc:`ImproperConnectionState`.

   .. versionadded:: 2.0

.. exception:: ResponseNotReady

   A subclass of :exc:`ImproperConnectionState`.

   .. versionadded:: 2.0

.. exception:: BadStatusLine

   A subclass of :exc:`HTTPException`.  Raised if a server responds with a HTTP

   status code that we don't understand.

   .. versionadded:: 2.0

The constants defined in this module are:

.. data:: HTTP_PORT

   The default port for the HTTP protocol (always ``80``).

.. data:: HTTPS_PORT

   The default port for the HTTPS protocol (always ``443``).

and also the following constants for integer status codes:

.. data:: responses

   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.

.. 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.

.. method:: HTTPConnection.endheaders()

   Send a blank line to the server, signalling the end of the headers.

.. 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.

.. _httpresponse-objects:

HTTPResponse Objects

--------------------

:class:`HTTPResponse` instances have the following methods and attributes:

.. method:: HTTPResponse.read([amt])

   Reads and returns the response body, or up to the next *amt* bytes.

.. method:: HTTPResponse.getheader(name[, default])

   Get the contents of the header *name*, or *default* if there is no matching

   header.

.. method:: HTTPResponse.getheaders()

   Return a list of (header, value) tuples.

   .. versionadded:: 2.4

.. attribute:: HTTPResponse.msg

   A :class:`mimetools.Message` instance containing the response headers.

.. attribute:: HTTPResponse.version

   HTTP protocol version used by server.  10 for HTTP/1.0, 11 for HTTP/1.1.

.. attribute:: HTTPResponse.status

   Status code returned by server.

.. attribute:: HTTPResponse.reason

   Reason phrase returned by server.
