How to ignore windows proxy settings with python urllib?

问题

I want Python to ignore Windows proxy settings when using urllib. The only way I managed to do that was disabling all proxy settings on Internet Explorer. Is there any programmatic way?

os.environ['no_proxy'] is not a good option, since I'd like to avoid proxy for all addresses.

回答1:

Pass to urlopen method

proxies={}

or try with:

urllib.getproxies = lambda x = None: {}

just after urllib import (Info found here).

回答2:

From the urlib2 documentation: Class urllib2.ProxyHandler([proxies]) ... To disable autodetected proxy pass an empty dictionary.

So what we want to do is this:

import urllib2
proxy = urllib2.ProxyHandler({}) # Pass empty dictionary to bypass proxy
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
socket = urllib2.urlopen('http://www.google.com')
content = socket.read() 

回答3:

According to document, you could pass, proxies=None or proxies={}

urllib.urlopen(some_url, proxies=None)

回答4:

I had trouble making request ignore the proxies. These did not work.

proxies=None or proxies={} 

This did work

proxies={'http':None}
