Question

I m using urllib.urlopen with some http proxies and sometimes (probably when they require authorization) I get the following prompt printed into the console:

Enter username for Private Proxy Access (country) at xxx.xxx.xxx.xxx:xxxx

How can I raise an exception on such thing happening?

Here s the example:

from urllib import urlopen

p =  64.79.209.238:36867 
print urlopen( http://google.com , proxies={ http :  http:// +p})

In case the mentioned proxy dies too soon, here are some replacements 64.79.197.36:43444, 64.79.209.203:34968, 64.79.197.36:43444, 209.59.207.197:3438

Answer 1

You need to overwrite FancyURLopener.prompt_user_passwd method:

class AuthorizationRequired(Exception):

    pass


class MyURLOpener(urllib.FancyURLopener):

    def prompt_user_passwd(self, host, realm):
        raise AuthorizationRequired()


opener = MyURLOpener(proxies={ http :  http:// +p})
fp = opener.open(url)

Answer 2

urllib.urlencode doesn t ever print that message. That method never hits the network in first place. Your problem is somewhere else.

I guess you re running some other daemon in background that prints the message.

Please provide exact reproducible code and message. Example of proxy that triggers the message would also be good.

Answer 3

I adapted Denis code a little to this:

import urllib
urllib.FancyURLopener.prompt_user_passwd = lambda *a, **k: (None, None)

It will disable password prompting altogether
