How to ignore "Enter username for Private Proxy Access" prompt?

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:

En开发者_如何转开发ter 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

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)

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.

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
