Python Proxy Error With Requests Library

问题:

I am trying to access the web via a proxy server in Python. I am using the requests library and I am having an issue with authenticating my proxy as the proxy I am using requires a password.

proxyDict = { 
          'http'  : 'username:mypassword@77.75.105.165', 
          'https' : 'username:mypassword@77.75.105.165'
        }
r = requests.get("http://www.google.com", proxies=proxyDict)

I am getting the following error:

Traceback (most recent call last):
File "<pyshell#13>", line 1, in <module>
r = requests.get("http://www.google.com", proxies=proxyDict)
File "C:\Python27\lib\site-packages\requests\api.py", line 78, in get

ValueError: invalid literal for int() with base 10: 'h6f2v6jh5dsxa@77.75.105.165'

How do I solve this?

Thanks in advance for your help.

You should remove the embedded username and password from proxyDict, and use the auth parameter instead.

import requests
from requests.auth import HTTPProxyAuth

proxyDict = { 
          'http'  : '77.75.105.165', 
          'https' : '77.75.105.165'
        }
auth = HTTPProxyAuth('username', 'mypassword')

r = requests.get("http://www.google.com", proxies=proxyDict, auth=auth)

I've been having a similar problem on Windows and found the only way to get requests to work was to set the proxies as environment variables before I started Python. For you this would be something like this:

set HTTP_PROXY=http://77.75.105.165
set HTTPS_PROXY=https://77.75.105.165

You might also want to check is there's a specific port required, and if so set it after the url. For example, if the port is 8443 then do:

set HTTP_PROXY=http://77.75.105.165:8443
set HTTPS_PROXY=https://77.75.105.165:8443

You can use urllib library for this.

from urllib import request
request.urlopen("your URL", proxies=urllib.getproxies())
