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.local: 3128' (.getproxies()). There's the obvious necessity of telling "something" my ID/pass *somehow*. An example of one iteration: ###################### import urllib2 proxy_handler = urllib2.ProxyHandler( { "http": "http:// myusername:@webfilter.xyz.local:3128" } ) opener = urllib2.build_opener( proxy_handler ) urllib2.install_opener( opener ) response = opener.open( "http://python.org"; ) print response ###################### I've tried situations using HTTPPasswordMgrWithDefaultRealm 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 "documentation" for non-basic stuffs with urllib2 is... uh... well, I'm sure ye olde pro's know... :) Cheers, and *any* help would be appreciated! -Larry -- http://mail.python.org/mailman/listinfo/python-list
