#1858 from Tarek Ziade:
Allow multiple repositories in .pypirc; see http://wiki.python.org/moin/EnhancedPyPI
for discussion.
The patch is slightly revised from Tarek's last patch: I've simplified
the PyPIRCCommand.finalize_options() method to not look at sys.argv.
Tests still pass.

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.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
.. 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.
|
|
|
|
|
|
|
|

Here is an example session that uses the ``GET`` method::
|
|
|
|
|
|
2008-05-26 13:32:26 -03:00
|
|
|
>>> import http.client
|
|
|
|
|
>>> conn = http.client.HTTPConnection("www.python.org")
|
2007-08-15 11:28:22 -03:00
|
|
|
>>> conn.request("GET", "/index.html")
|
|
|
|
|
>>> r1 = conn.getresponse()
|
2007-09-04 04:15:32 -03:00
|
|
|
>>> print(r1.status, r1.reason)
|
2007-08-15 11:28:22 -03:00
|
|
|
200 OK
|
|
|
|
|
>>> data1 = r1.read()
|
|
|
|
|
>>> conn.request("GET", "/parrot.spam")
|
|
|
|
|

Here is an example session that shows how to ``POST`` requests::

|
|
|
|
|

|
|
|
>>> import http.client, urllib.parse
