how to set proxy with authentication in selenium chromedriver python?

Question

I am creating a script that crawls one website to gather some data but the problem is that they blocked me after too many requests but using a proxy I can send more request then currently I do. I have integrated proxy with chrome option --proxy-server

options.add_argument('--proxy-server={}'.format('http://ip:port'))

but I am using a paid proxy so it requires authentication and as below screenshot it gives the alert box for username and password

Then I tried to use it with username and password

options.add_argument('--proxy-server={}'.format('http://username:password@ip:port'))

But it also does not seems to work. I was looking for a solution and found below solution and I used it with the chrome extension proxy auto auth and without the chrome extension

proxy = {'address': settings.PROXY,              'username': settings.PROXY_USER,              'password': settings.PROXY_PASSWORD}  capabilities = dict(DesiredCapabilities.CHROME) capabilities['proxy'] = {'proxyType': 'MANUAL',                              'httpProxy': proxy['address'],                              'ftpProxy': proxy['address'],                              'sslProxy': proxy['address'],                              'noProxy': '',                              'class': "org.openqa.selenium.Proxy",                              'autodetect': False,                              'socksUsername': proxy['username'],                              'socksPassword': proxy['password']} options.add_extension(os.path.join(settings.DIR, "extension_2_0.crx")) # proxy auth extension 

but neither of above worked properly it seems working because after above code the proxy authentication alert disappeared and when I checked my IP by googling what is my IP and confirmed that is not working.

please anyone who can help me to authenticate the proxy server on chromedriver.

Selenium Chrome Proxy Authentication

Setting chromedriver proxy with Selenium using Python

If you need to use a proxy with python and Selenium library with chromedriver you usually use the following code (Without any username and password:

chrome_options = webdriver.ChromeOptions() chrome_options.add_argument('--proxy-server=%s' % hostname + ":" + port) driver = webdriver.Chrome(chrome_options=chrome_options) 

It works fine unless proxy requires authentication. if the proxy requires you to log in with a username and password it will not work. In this case, you have to use more tricky solution that is explained below. By the way, if you whitelist your server IP address from the proxy provider or server it should not ask proxy credentials.

HTTP Proxy Authentication with Chromedriver in Selenium

To set up proxy authentication we will generate a special file and upload it to chromedriver dynamically using the following code below. This code configures selenium with chromedriver to use HTTP proxy that requires authentication with user/password pair.

import os import zipfile  from selenium import webdriver  PROXY_HOST = '192.168.3.2'  # rotating proxy or host PROXY_PORT = 8080 # port PROXY_USER = 'proxy-user' # username PROXY_PASS = 'proxy-password' # password   manifest_json = """ {     "version": "1.0.0",     "manifest_version": 2,     "name": "Chrome Proxy",     "permissions": [         "proxy",         "tabs",         "unlimitedStorage",         "storage",         "<all_urls>",         "webRequest",         "webRequestBlocking"     ],     "background": {         "scripts": ["background.js"]     },     "minimum_chrome_version":"22.0.0" } """  background_js = """ var config = {         mode: "fixed_servers",         rules: {         singleProxy: {             scheme: "http",             host: "%s",             port: parseInt(%s)         },         bypassList: ["localhost"]         }     };  chrome.proxy.settings.set({value: config, scope: "regular"}, function() {});  function callbackFn(details) {     return {         authCredentials: {             username: "%s",             password: "%s"         }     }; }  chrome.webRequest.onAuthRequired.addListener(             callbackFn,             {urls: ["<all_urls>"]},             ['blocking'] ); """ % (PROXY_HOST, PROXY_PORT, PROXY_USER, PROXY_PASS)   def get_chromedriver(use_proxy=False, user_agent=None):     path = os.path.dirname(os.path.abspath(__file__))     chrome_options = webdriver.ChromeOptions()     if use_proxy:         pluginfile = 'proxy_auth_plugin.zip'          with zipfile.ZipFile(pluginfile, 'w') as zp:             zp.writestr("manifest.json", manifest_json)             zp.writestr("background.js", background_js)         chrome_options.add_extension(pluginfile)     if user_agent:         chrome_options.add_argument('--user-agent=%s' % user_agent)     driver = webdriver.Chrome(         os.path.join(path, 'chromedriver'),         chrome_options=chrome_options)     return driver  def main():     driver = get_chromedriver(use_proxy=True)     #driver.get('https://www.google.com/search?q=my+ip+address')     driver.get('https://httpbin.org/ip')  if __name__ == '__main__':     main() 

Function get_chromedriver returns configured selenium webdriver that you can use in your application. This code is tested and works just fine.

Answer 2

Here is a quick, creative solution that doesn't require modification of selenium's Options or uploading a file to chromedriver. It makes use of pyautogui (can use any python package that simulates key presses) to enter proxy auth details. It also uses threading to account for chrome authentication popup window that would otherwise pause the script.

import time from threading import Thread import pyautogui from selenium.webdriver.chrome.options import Options from selenium import webdriver  hostname = "HOST_NAME" port = "PORT" proxy_username = "USERNAME" proxy_password = "PASSWORD"  chrome_options = Options() chrome_options.add_argument('--proxy-server={}'.format(hostname + ":" + port)) driver = webdriver.Chrome(options=chrome_options)   def enter_proxy_auth(proxy_username, proxy_password):     time.sleep(1)     pyautogui.typewrite(proxy_username)     pyautogui.press('tab')     pyautogui.typewrite(proxy_password)     pyautogui.press('enter')   def open_a_page(driver, url):     driver.get(url)   Thread(target=open_a_page, args=(driver, "http://www.example.com/")).start() Thread(target=enter_proxy_auth, args=(proxy_username, proxy_password)).start() 

NOTE: For any serious project or test suite I would recommend opting for a more robust solution. However, if you are just experimenting and require a quick and effective solution, this is an option.
