302s and losing cookies with urllib2

Question

I am using liburl2 with CookieJar / HTTPCookieProcessor in an attempt to simulate a login to a page to automate an upload.

I\'ve seen some questions and answers on this,

Answer 1

I've just got a variation of the below working for me, at least when trying to read Atom from http://www.fudzilla.com/home?format=feed&type=atom

I can't verify that the below snippet will run as-is, but might give you a start:

import cookielib
cookie_jar = cookielib.LWPCookieJar()
cookie_handler = urllib2.HTTPCookieProcessor(cookie_jar)
handlers = [cookie_handler] #+others, we have proxy + progress handlers
opener = apply(urllib2.build_opener, tuple(handlers + [_FeedURLHandler()])) #see http://code.google.com/p/feedparser/source/browse/trunk/feedparser/feedparser.py#2848 for implementation of _FeedURLHandler
opener.addheaders = [] #may not be needed but see the comments around the link referred to below
try:
    return opener.open(request) #see http://code.google.com/p/feedparser/source/browse/trunk/feedparser/feedparser.py#2954 for implementation of request
finally:
    opener.close()
