How to check if the proxy is working through which I want to send requests, python?

Question

Python

I need to start Selenium by writing that it will work through a proxy - webdriver.Firefox(proxy=self.proxy), but if the proxy is not working, then the browser is endlessly loaded. How can I check if the proxy is working using Python? (os windows)

Answer 1

It is possible so;

import urllib
import socket

socket.setdefaulttimeout(2) # timeout. increase for slow proxies

try:
    urllib.urlopen(
        "http://ya.ru",
        proxies={'http':'http://example.com:8080'} # your proxy here
    )
except IOError:
    print "Bad proxy!" # do it if proxy connect is failed
else:
    print "All was OK" # do it if all ok

Play around with timeouts. Depending on what proxies you have.
