Hello, I have some very serious trouble getting cookes to work. After a lot of work (urllib2 is severly underdocumented, arcane and overengineerd btw) I'm finally able to accept cookes from a server. But I'm still unable to return them to a server. Specifically the script im trying to do logs on to a server, get a session cookie and then tries to access a secure page using the same session cookie. But the cookie header cookielib produces is very different from the header it received.
This example demonstrates it: import cookielib import urllib import urllib2 # Install an opener that can handle cookies policy = cookielib.DefaultCookiePolicy(rfc2965 = True) cj = cookielib.CookieJar(policy) opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) urllib2.install_opener(opener) # Login to the server url = "http://server/dologin.htm"; params = urllib.urlencode({"user" : "foo", "pass" : "pwd"}) req = urllib2.Request(url, params) handle = urllib2.urlopen(req) # So far so good, the request should have added a cookie to the jar. # The cookie header looks like this: # # Set-Cookie: SessionId="acf941a1fb4895ed"; Version=1; Path=/ # assert len(cj) == 1 # Hack around the code in cookielib.CookieJar._cookie_attrs(), # specifically the part that quotes, search for "quote_re" in the # file cookielib.py. cj._cookies_for_request(req)[0].version = 0 # Now request a secure page from the server req = urllib2.Request("http://server/secure.htm";) cj.add_cookie_header(req) handle = urllib2.urlopen(req) # Here is where it doesn't work unless the hack is applied. The cookie # header that is sent without the hack looks like this: # # Cookie: $Version=1; SessionId=\"66b908e5025d93ed\"; $Path="/" # # It is not accepted by the server, probably because the SessionID # string is wrong. -- mvh Björn -- http://mail.python.org/mailman/listinfo/python-list
