Running selenium behind a proxy server
You need to set desired capabilities or browser profile, like this:
profile = webdriver.FirefoxProfile()
profile.set_preference("network.proxy.type", 1)
profile.set_preference("network.proxy.http", "proxy.server.address")
profile.set_preference("network.proxy.http_port", "port_number")
profile.update_preferences()
driver = webdriver.Firefox(firefox_profile=profile)

Accessing a website behind a proxy server with Google Chrome headless, using Selenium, which works when using Fiddler
I used network monitor to see that the headless chrome calls were resolving to a website IP address, rather than that of the proxy, so it looked like headless chrome wasn't using the default proxy, as suspected.
In the end, configuring the nunit tests to pass the proxy server in to headless chrome using the --proxy-server argument did the trick.
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",
"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",

};
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.
