Pycurl proxy authentication anyone?

11-05-2003

I've been trying to get a simple pycurl script working with an
authenticating proxy, here is the code (with changes to protect the
guilty!):

from pycurl import *
import StringIO

b = StringIO.StringIO()
c = Curl()

c.setopt(URL, "http://www.google.com/")
c.setopt(VERBOSE,1)
c.setopt(HTTPHEADER, ["User-Agent: Mozilla/5.001 (windows; U; NT4.0;
en-us) Gecko/25250101", "Agent: "])
c.setopt(PROXY, "dummyproxy")
c.setopt(PROXYPORT,80)
c.setopt(PROXYUSERPWD,"dummyuser:dummypasswd")
c.setopt(HTTPAUTH,

#NTLM
c.setopt(WRITEFUNCTION, b.write)
c.setopt(FOLLOWLOCATION, 1)
c.setopt(MAXREDIRS, 5)

c.perform()
print b.getvalue()

And I get....

* About to connect() to dummyproxy:80
* Connected to dummyproxy (10.10.10.10) port 80

<p>You must authenticate with a proxy server before this request can be

The username

assword combo are correct.

I'm stumped! suggestions gratefully accepted..

Shouldn't that last line be:

c.setopt(PROXYAUTH,

#NTLM
