Problem when applying Patch from issue1424152 to get https overauthenticating proxies working with urllib2 in Python 2.5
 

Hi,
I'm trying to get https requests working through an authenticating
proxy with urllib2 in Python 2.5, I'm aware that this isn't supported
"out of the box", so applied the patch http://bugs.python.org/file9753/http-tunnel-urllib
linked from http://bugs.python.org/issue1424152 , my baseline test
program is the following:

p = "user:pass@proxy:port"
proxy_handler = urllib2.ProxyHandler({"http": p, "https": p})
urllib2.install_opener( urllib2.build_opener( urllib2.HTTPHandler,

urllib2.HTTPSHandler,

proxy_handler))

request = urllib2.Request( "https://groups.google.com")
response = urllib2.urlopen(request)

Unfortunately this doesn't work, the call stack being:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 121, in urlopen
return _opener.open(url, data)
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 374, in open
response = self._open(req, data)
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 392, in _open
'_open', req)
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 353, in _call_chain
result = func(*args)
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 1108, in https_open
return self.do_open(httplib.HTTPSConnection, req)
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\urllib2.py", line 1075, in do_open
raise URLError(err)
urllib2.URLError: <urlopen error (1, 'error:140770FC:SSL
routines:SSL23_GET_SERVER_HELLO:unknown protocol')>

Does anyone know why I might be hitting this issue?
Any help is greatly appreciated,
thanks

I've reduced my code to the following:

import urllib2

p = "https://user:pass@myproxy:port"
proxy_handler = urllib2.ProxyHandler({"https": p})
urllib2.install_opener(urllib2.build_opener(proxy_ handler))
request = urllib2.Request( "https://groups.google.com")
response = urllib2.urlopen(request)

and it is now failing with:

Traceback (most recent call last):
File "D:\p4\depot\Development\HEAD\Build\ReleaseSystem\ DownloadSystem
\test.py", line 12, in <module>
response = urllib2.urlopen(request)
File "C:\Python25\lib\urllib2.py", line 121, in urlopen
return _opener.open(url, data)
File "C:\Python25\lib\urllib2.py", line 379, in open
response = self._open(req, data)
File "C:\Python25\lib\urllib2.py", line 397, in _open
'_open', req)
File "C:\Python25\lib\urllib2.py", line 358, in _call_chain
result = func(*args)
File "C:\Python25\lib\urllib2.py", line 1115, in https_open
return self.do_open(httplib.HTTPSConnection, req)
File "C:\Python25\lib\urllib2.py", line 1082, in do_open
raise URLError(err)
urllib2.URLError: <urlopen error Tunnel connection failed: 407 Proxy
Authentication Required>

I thought the proxy_handler should take care of the authentication?

Thanks for your help
