How to use authenticated proxy in selenium chromed

Question

After searching for many hours I am starting to think this is impossible.

I need to run Chrome through selenium using different authenticated (not public) proxy's for each run.

PROXY_IP = "<some IP address>"
UID = "<the user id>"
PWD = "<the password">

options = webdriver.ChromeOptions()
options.add_argument("--proxy-server=%s:%s@%s" % (UID,PWD,PROXY_IP))

driver = webdriver.Chrome(executable_path=".\\driver\\chromedriver.exe",
                          chrome_options=options)
driver.get("<site URL>")

Chrome will fire-up and display the error:

This webpage is not available
ERR_NO_SUPPORTED_PROXIES

If I use a public proxy requiring no authentication like this...

PROXY_IP = "<public proxy IP address>"

options = webdriver.ChromeOptions()
options.add_argument("--proxy-server=%s" % PROXY_IP)

driver = webdriver.Chrome(executable_path=".\\driver\\chromedriver.exe",
                          chrome_options=options)
driver.get("<site URL>")

...it runs just fine and displays the site while using the proxy.

I also tried a variant with http:// in front of the user ID:

options.add_argument("--proxy-server=http://%s:%s@%s" % (UID,PWD,PROXY_IP))

The fact that I have searched far and wide and haven't found a solution leads me to believe none might exist.

I did find this but I can't make sense out of it:

selenium chromedriver authentication proxy

Not sure what browswermob-proxy is or is supposed to do or how to implement and test in Python. I hate piling up band-aid solutions unless they are absolutely necessary.

Answer 1

after trying many solutions that didn't actually work properly, i finally managed to set the authenticated proxy using the suggested extension from previous answers. what you need to do is to enter this link:

http://crxextractor.com/ and paste this url: https://www.crx4chrome.com/crx/1446/

It will let you download the extention as a .crx file without installing it. than i used this code:

proxy = {'address': 'pr.oxylabs.io:7777',
     'username': 'USERNAME',
     'password': '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 = webdriver.ChromeOptions()
options.add_extension("./extension_2_0_0_0.crx")
driver = webdriver.Chrome(executable_path=CHROME_PATH, desired_capabilities=capabilities, chrome_options=options)

I have checked for most of the solutions on the web and for none of them authentication via chrome/firefox desired capabilities is working. Check this link: https://github.com/webdriverio/webdriverio/issues/324. Finally the temporary solution is to whitelist your IP address with the proxy provider.

I could not find any solution for chrome. We can not add extensions with headless option. I am using Heroku with chrome-buildpack. There are following options

1. Use xvfb instead of headless options and install extension
2. Use local proxy forwarder that forwards traffic to authenticated proxy; we can use Squid, mitProxy, or something like proxy-login-automator

Instead of these workaround I switched to Firefox where i was able to fill Username and Password on Proxy authentication Pop-up. Like given below. Following code is for Ruby using Capybara. You should be able to do something like this on your platform

page.driver.browser.switch_to.alert.send_keys('proxy-username' + Selenium::WebDriver::Keys::KEYS[:tab] + 'my-password')
page.driver.browser.switch_to.alert.accept

Answer 4

THis is a temporary solution might work in initial state: Code is in Python: Download the plugin first from chrome plugin store : Proxy-Auto-Auth_v2.0.crx

        options = webdriver.ChromeOptions()
        options.add_extension("./Proxy-Auto-Auth_v2.0.crx")) #this will provide you a window to enter user name and proxy 
        driver = webdriver.Remote(command_executor=selenium_server,desired_capabilities=options.to_capabilities())

        or 

        driver = webdriver.Chrome(chrome_options=options)

Answer 5

I tryed lot of time to do the same.

Chrome is using only proxy of the OS where it is installed. You can check it by going to options-> find: proxy -> change proxy settings

So without additional addons and configuring this addons you cannot do this.

Or you can change your OS proxy settings -- this is much easier.

Also you can use phantomjs -- it have the same engine(WebKit) as chrome. using something like this:

String PROXY = proxyIP + ":" + proxyPort;
String proxyAuth= proxyUser + ":" + proxyPass;
        OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
                    proxy.HttpProxy = PROXY;
                    proxy.FtpProxy = PROXY;
                    proxy.SslProxy = PROXY;
                    proxy.SocksProxy = PROXY;

    var serviceJS = PhantomJSDriverService.CreateDefaultService(phantomPath);
    serviceJS.AddArguments("--proxy=" + PROXY, "--proxy-type=http", "--proxy-auth=" + proxyAuth);
