Greetings, Pythonistas!
My employer has a Squid Proxy between my Python programs and The
Internet.
I've searched high-and-low, and can only find examples online of how
to do basic authentication to connect TO an external Web Server, but
not how to go THROUGH a (corporate) Proxy, thus my question here.
I've tried all sorts of permutations based on my findings, but
(obviously) nothing's working for me. I've come across conflicting
information, including that urllib2 can't/won't do what I'm needing,
though this statement was a couple years old.
I'm running Python 2.5 on Windows XP SP2 64-bit. The Proxy is Squid
(don't know what version, but can find out if this is relevant).
urllib2 grabs the Proxy info fine: 'http': 'http://webfilter.xyz.l ocal:
3128' (.getproxies()) . There's the obvious necessity of telling
"something" my ID/pass *somehow*.
An example of one iteration:
############### #######
import urllib2
proxy_handler = urllib2.ProxyHa ndler( { "http": "http://
myusername:@web filter.xyz.loca l:3128" } )
opener = urllib2.build_o pener( proxy_handler )
urllib2.install _opener( opener )
response = opener.open( "http://python.org" )
print response
############### #######
I've tried situations using HTTPPasswordMgr WithDefaultReal m and its
add_password method, also to no avail. (Again, THIS sort of thing
seems related to the -external- Web Server, _not_ going *through* a
Proxy. 'Course, I could be wrong. But if I am, I couldn't get this
to work, either. ;)
I've looked at what's happening with Wireshark; Py/my program/urllib2
makes the initial page request, Proxy replies HTTP Error 407: Proxy
Authentication Required, and Py/my program/urllib2 simply stops at
that, reporting the message/error.
Please forgive me; I've been programming in Python for a few years
now, but never had to deal with Web Proxies. I *have* tried to RTFMs,
but the "documentat ion" for non-basic stuffs with urllib2 is... uh...
well, I'm sure ye olde pro's know... :)
Cheers, and *any* help would be appreciated!
