how to set proxy with authentication in selenium chromedriver python?

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",

            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.

Use selenium-wire.

Example code from the documentation:

HTTP proxies

from seleniumwire import webdriver

options = {
    'proxy': {
        'http': 'http://user:[email protected]:8888',
        'https': 'https://user:[email protected]:8888',
        'no_proxy': 'localhost,127.0.0.1'
    }
}

driver = webdriver.Chrome(seleniumwire_options=options)

SOCKS proxies

from seleniumwire import webdriver

options = {
   'proxy': {
        'http': 'socks5://user:[email protected]:8888',
        'https': 'socks5://user:[email protected]:8888',
        'no_proxy': 'localhost,127.0.0.1'
    }
}
driver = webdriver.Chrome(seleniumwire_options=options)

Install with:

pip install selenium-wire

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.

After hours of digging around with the same problem that you had, I came across this website https://botproxy.net/docs/how-to/setting-chromedriver-proxy-auth-with-selenium-using-python/. I tested it out and worked for me perfectly.
