[Tutor] twisted web client authentication?

[Paul de Vries]

Hi

Made something that connects to a httpserver and parses the xml stream it sends.
The webserver it has to connect to uses digest authentication.

The problem is I don't have a clue how to use digest auth with twisted.web.client.
Couln't find any code examples for this.
Can somebody help me with this? ( I'm not a python programmer so please be gentle)

thanks in advance

the code I put together:

from twisted.internet import  reactor
from twisted.internet.defer import Deferred
from twisted.internet.protocol import Protocol
from twisted.web.client import Agent
from twisted.web.http_headers import Headers
from StringIO import StringIO
from elementtree import ElementTree


class BeginPrint(Protocol):
   def __init__(self, finished):
       self.finished = finished
       self.dataStream = StringIO()

   def dataReceived(self, bytes):
       display = bytes
       #print 'some data received:'
       #print display
       context = ElementTree.iterparse(StringIO(bytes), events = ("start", "end"))
       context = iter(context)
       event, root = context.next()

       for event, elem in context:
           if elem.tag == "Tag":
               print "Tag "
           root.clear()


   def connectionLost(self, reason):
       print 'finished receiving', reason.getErrorMessage()

agent = Agent(reactor)

d = agent.request('GET', 'http:someadress', Headers({'User-Agent': ['Twisted web client']}), None)

def cbResponse(response):
   print 'Response version: ', response.version
   finished = Deferred()
   response.deliverBody(BeginPrint(finished))
   return finished

d.addCallback(cbResponse)
reactor.run()
