Python Requests behind proxy

I'm behind a corporate proxy (Isa Server).

When using urllib2 I can connect through the proxy to the internet without any problem, but when using the requests library I can't.

Here is my urllib2 code:

proxy = urllib2.ProxyHandler({})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)

page = urllib2.urlopen('http://www.google.com')
print page.getcode()

This prints '200' and works fine

However when doing the same with requests I get a 407 code and doesn't work.

proxy_dict = {
    'http': 'http://10.20.23.5:8080',
    'https': 'ftp://10.20.23.5:8080',
    'ftp': 'https://10.20.23.5:8080'
}

page = requests.get('http://www.google.com', proxies=proxy_dict)
print page.status_code
print page.reason

This prints '407' and the reason: 'Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )'

Even if I pass to requests the proxies from urllib2 doesn't work either:

page = requests.get('http://http://www.google.com', proxies=urllib2.getproxies())

Urllib2 is doing something that requests is not.

Any help?

If your proxy requires authentication, you need to set up those variables:

proxy_dict = {
    'http': 'http://username:[email protected]:8080',
    'https': 'https://username:[email protected]:8080',
    'ftp': 'ftp://username:[email protected]:8080'
}
