Twisted: Get Protected HTTPS Page via Proxy with Authentication

[Robert Hancock]

from twisted.web import client
from twisted.interne t import reactor
import base64
import sys

def printPage(data) :
print data
reactor.stop()

def printError(fail ure):
print >sys.stderr, "Error:", failure.getErro rMessage()
reactor.stop()

if len(sys.argv) == 4:
url = sys.argv[1]
username = sys.argv[2]
password = sys.argv[3]

basicAuth = base64.encodest ring('%s:%s' % (username, password))
authHeader = "Basic " + basicAuth.strip ()

client.getPage( url, headers={"Autho rization":
authHeader}).ad dCallback(print Page).addErrbac k(printError)
reactor.run()
else:
print 'Usage: get_web_page.py <URL>'

If I run this against a password protected HTTP(S) site from a host
that has direct access to the Internet it works fine. I now have to
move it behind a proxy that requires authentication. The Twisted
documentation did not make it clear (to me) how to add proxy
authentication and I cannot find an example on the Internet.

I've tried adding an additional Proxy-Authentication header to the
call, but that doesn't help Any ideas would be greatly appreciated.

This works:
# Proxy credentials
proxyAuth = base64.encodest ring('%s:%s' % (proxy_username ,
proxy_password) )
proxy_authHeade r = "Basic " + proxyAuth.strip ()

# Web site credentials
basicAuth = base64.encodest ring('%s:%s' % (username,
password))
authHeader = "Basic " + basicAuth.strip ()

return client.getPage( url, headers={"Autho rization":
authHeader, 'Proxy-Authenticate': proxy_authHeade r})
