python 407 error

[Aliabbas Petiwala]

I am unable to figure out where to enter the proxy information in python, i get a 407 proxy error,it seems python does not detect the proxy server automatically as i have uninstalled IE.Please let me know the config for iitb proxy

>>> urllib2.urlopen('http://www.python.org/')

Traceback (most recent call last):

import urllib2

proxy = urllib2.ProxyHandler({'http': 'ldap_id:ldap_password.@netmon.iitb.ac.in:80'})

opener = urllib2.build_opener(proxy)

urllib2.install_opener(opener)

407 is when the Proxy Authentication went wrong. Here, it means urllib2 guessed the proxy correctly (from the environment variables, if not IE), but not the LDAP ID and password, or the password wasn't urlencoded. A more complete solution would be:

import urllib2

from urllib import quote

ldap_ip = quote('<LDAP_ID>')

ldap_password = quote('<LDAP_PASSWORD>')

proxy = urllib2.ProxyHandler({'http': ldap_id+':'+ldap_password+'@netmon.iitb.ac.in:80'})

opener = urllib2.build_opener(proxy)

urllib2.install_opener(opener)

print urllib2.urlopen('http://www.google.com').read()

PS: The way urllib guesses the Proxy settings: environment variabes. So I guess changing the environment variable in the python script itself would also do. If not http_proxy (or https_proxy) env values are set, only then does it look into the Windows Registry.

PSS: How come you uninstalled IE, I don't think Windows let's one do that.

Set the environment variables..... its the best thing to do in this case...

I have tried both env variables and urllib proxy function.... former
one appears to be connecting faster....

i updated urllib2.py with that code and it works, no need to set it all the time.

@pritam IE can be un installed in win 7 , google for it, ms allows it in the control panel. Its the best thing to do with a win7.

[Aliabbas Petiwala]

which environment variables and where?
