cookielib und proxyauth

[Clython]

Hallo

da ich nicht besonders Lust habe stundenlang im dunklen zu tappen mal folgende Frage:

import urllib2
import cookielib


the_url = 'http://www.lexisnexis.com/de/business/search/loadForm.do'
user_agent = 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050514 Firefox/1.0.4'
headers = { 'User-Agent' : user_agent,
            "Accept" : "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5",
"Accept-Language" : "en-us,en;q=0.5",
#"Accept-Encoding" : "gzip,deflate",
"Accept-Charset" : "ISO-8859-1,utf-8;q=0.7,*;q=0.7",
"Keep-Alive" : "300",
"Proxy-Connection" : "keep-alive",
"Proxy-Authorization" : "Basic czAxNzEyMTg6Kk5hcnV0MA=="}
# Create an OpenerDirector with support for Basic HTTP Authentication...
auth_handler = urllib2.ProxyBasicAuthHandler()
auth_handler.add_password('unizh.ch', 'proxy.unizh.ch:3128', name, pass)
opener = urllib2.build_opener(auth_handler)
    
#
    
cj = cookielib.CookieJar()
opener2 = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj)) 

# ...and install it globally so it can be used with urlopen.
urllib2.install_opener(opener)
urllib2.install_opener(opener2)
req = urllib2.Request(the_url, None, headers)
side = urllib2.urlopen(req)
html = side.read()
file = open("result.htm", "w")
file.write(html)
file.close()

Mit diesem Aufruf habe ich jetzt genau den HTTP-Aufruf des Browsers simuliert, ohne die Cookies. Wie krieg ich jetzt die noch hin, in der Hoffnung, dass die Authentifizierung dann stimmt?

Ich hab das grösste Problem gefunden (danke ethereal)! Wenn ich den Code ausführe, geht die Verbindung nicht über den Uni-Proxy (was für die Authentifizierung sorgt). Was mache ich falsch? Laut meinen Beispielen sollte das so funktionieren?

Kann mir mal jemand sagen, warum ich bei diesem Code:

import urllib2
import cookielib

#the_url = 'http://www.lexisnexis.com/de/business/search/loadForm.do'
the_url = 'http://www.meineip.de'

"Proxy-Authorization" : "Basic czAxNzEyMTg6Kk5hcnV0MA=="}
req = urllib2.Request(the_url, None, headers)

cj = cookielib.CookieJar()

passmgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
passmgr.add_password(None, 'http://proxy.unizh.ch:3128', user, passwd)
authinfo = urllib2.ProxyDigestAuthHandler(passmgr)
proxy_support = urllib2.ProxyHandler({"http" : "proxy.unizh.ch:3128"})

opener = urllib2.build_opener(proxy_support, authinfo, urllib2.HTTPCookieProcessor(cj))

urllib2.install_opener(opener)

f = urllib2.urlopen("http://www.meineip.de")

buf = f.read()
print buf
f.close()

diese Fehlermeldung:
