Proxy connection with Python
I have been attempting to connect to URLs from python. I have tried: urllib2, urlib3, and requests. It is the same issue that i run up against in all cases. Once I get the answer I imagine all three of them would work fine.
The issue is connecting via proxy. I have entered our proxy information but am not getting any joy. I am getting 407 codes and error messages like: HTTP Error 407: Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )
However, I can connect using another of other applications that go through the proxy, git for example. When I run git config --get htpp.proxy it returns the same values and format that I am entering in Python namely
http://username:password@proxy:8080
An example of code in requests is
import requests
proxy = {"http": "http://username:password@proxy:8080"}
url = 'http://example.org'
r = requests.get(url, proxies=proxy)
print r.status_code
Thanks for your time
Answer
In the requests module, proxy authentication is performed as shown:
import requests
proxies = {'http':'http://x.x.x.x', 'https':'https://x.x.x.x'}
auth = requests.auth.HTTPProxyAuth('username', 'password')
r = requests.get('http://www.example.com', proxies = proxies, auth = auth)
print r.status_code, r.reason
