: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
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
#2452: timeout is used for all blocking operations.

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

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, :)

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')

.. 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.

.. 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.

Here is an example session that uses the ``GET`` method::
>>> import httplib
>>> conn = httplib.HTTPConnection("www.python.org")
>>> conn.request("GET", "/index.html")
>>> r1 = conn.getresponse()
>>> print r1.status, r1.reason
200 OK
>>> data1 = r1.read()
>>> conn.request("GET", "/parrot.spam")
>>> r2 = conn.getresponse()
>>> print r2.status, r2.reason
404 Not Found
>>> data2 = r2.read()
>>> conn.close()

Here is an example session that uses ``HEAD`` method. Note that ``HEAD`` method
never returns any data. ::
>>> import httplib
>>> conn = httplib.HTTPConnection("www.python.org")
>>> conn.request("HEAD","/index.html")
>>> res = conn.getresponse()
>>> print res.status, res.reason
200 OK
>>> data = res.read()
>>> print len(data)
0
>>> data == ''
True

Here is an example session that shows how to ``POST`` requests::
>>> import httplib, urllib
>>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})
>>> headers = {"Content-type": "application/x-www-form-urlencoded",
... "Accept": "text/plain"}
>>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80")
>>> conn.request("POST", "/cgi-bin/query", params, headers)
>>> response = conn.getresponse()
>>> print response.status, response.reason
200 OK
>>> data = response.read()
>>> conn.close()
