How do I set proxy for chrome in python webdriver? – Stack …

I had an issue with the same thing. ChromeOptions is very weird because it’s not integrated with the desiredcapabilities like you would think. I forget the exact details, but basically ChromeOptions will reset to default certain values based on whether you did or did not pass a desired capabilities dict.
I did the following monkey-patch that allows me to specify my own dict without worrying about the complications of ChromeOptions
change the following code in /selenium/webdriver/chrome/
def __init__(self, executable_path=”chromedriver”, port=0,
chrome_options=None, service_args=None,
desired_capabilities=None, service_log_path=None, skip_capabilities_update=False):
“””
Creates a new instance of the chrome driver.
Starts the service and then creates new instance of chrome driver. :Args:
– executable_path – path to the executable. If the default is used it assumes the executable is in the $PATH
– port – port you would like the service to run, if left as 0, a free port will be found.
– desired_capabilities: Dictionary object with non-browser specific
capabilities only, such as “proxy” or “loggingPref”.
– chrome_options: this takes an instance of ChromeOptions
if chrome_options is None:
options = Options()
else:
options = chrome_options
if skip_capabilities_update:
pass
elif desired_capabilities is not None:
(_capabilities())
desired_capabilities = _capabilities()
rvice = Service(executable_path, port=port,
service_args=service_args, log_path=service_log_path)
()
try:
RemoteWebDriver. __init__(self,
rvice_url,
desired_capabilities=desired_capabilities)
except:
raise
self. _is_remote = False
all that changed was the “skip_capabilities_update” kwarg. Now I just do this to set my own dict:
capabilities = dict()
if not “chromeOptions” in capabilities:
capabilities[‘chromeOptions’] = {
‘args’: [],
‘binary’: “”,
‘extensions’: [],
‘prefs’: {}}
capabilities[‘proxy’] = {
‘Proxy’: “%s:%i”%(proxy_address, proxy_port),
‘ftpProxy’: “%s:%i”%(proxy_address, proxy_port),
‘sslProxy’: “%s:%i”%(proxy_address, proxy_port),
‘noProxy’: None,
‘proxyType’: “MANUAL”,
‘class’: “”,
‘autodetect’: False}
driver = ( executable_path=”path_to_chrome”, desired_capabilities=capabilities, skip_capabilities_update=True)

How to set proxy in Selenium : Tutorial | BrowserStack

What is a proxy? A proxy is an intermediary between client requests and server responses. Proxies are primarily used to ensure privacy and encapsulation between numerous interactive systems. A proxy can also provide an added layer of security by operating as a firewall between client and web servers. This is especially useful when the websites that clients use have to be labeled as allowed or blocked based on the website content. Often, websites will block IPs that make too many requests, and proxies are a way to get around this. Testing with Proxy ServersProxy servers are most useful for executing localization tests. Let’s say a tester wants to open an E-commerce website and check that the proper language settings and currency appear for users from a specific easy way to verify this is to access the website as a user would from a target location. Obviously, like most tests, it would be easier to automate this activity, especially when a website has to be checked from multiple lenium is the most widely used tool for running automated browser tests. Essentially, developers can use Selenium to monitor browser and website behavior without opening and executing a full browser instance. This article will detail how to set up a proxy server and use it to access the website via tting up a Proxy ServerMany free proxy servers are unauthenticated, which simply means that a username and password are not unauthenticated proxy server in Selenium can be set up with the following steps:Import Selenium WebDriver from the packageDefine the proxy server (IP:PORT)Set ChromeOptions()Add the proxy server argument to the optionsAdd the options to the Chrome() instancefrom selenium import webdriver
PROXY = “11. 456. 448. 110:8080”
chrome_options = romeOptions()
d_argument(‘–proxy-server=%s’% PROXY)
chrome = (chrome_options=chrome_options)
(“)Use this Chrome WebDriver instance to execute tests that incorporate the proxy server. For example, the following code snippet tests to ensure that a search field shows the user’s current city as the default testUserLocationZurich(self):
()
search = (‘user-city’)
sertIn(‘Zurich’, )In order to test a website from multiple locations by making this code reusable across separate tests, define a method that takes the proxy IP address as an argument. Testers can run tests using an unauthenticated server. However, if they wish to use an authenticated server, they can follow the procedure thenticated ProxyAuthenticated proxy servers can be tedious to use in automated tests as there’s no built-in way to pass along proxy server credentials in Selenium. As of now, there are two options to handle authenticated proxies. The right choice depends on the testers’ requirements. It depends on factors like the version of Selenium in use and the headless browser being used in ’s learn how to use it simply. The best way to integrate authenticated proxies with Selenium is by using PhantomJS as a headless browser instead of the Chrome ever, it is also possible to add a browser extension that does the authentication for Selenium. While this approach is more complex, it can be used with the latest version of Selenium, which may be a requirement for some development first step is creating a Chrome extension by including two files in an archive, named config = {
mode: “fixed_servers”,
rules: {
singleProxy: {
scheme: “”,
host: “YOUR_PROXY_ADDRESS”,
port: parseInt(PROXY_PORT)},
bypassList: [“”]}};
({value: config, scope: “regular”}, function() {});
function callbackFn(details) {
return {
authCredentials: {
username: “PROXY_USERNAME”,
password: “PROXY_PASSWORD”}};}
dListener(
callbackFn,
{urls: [““]},
[‘blocking’]);{
“version”: “1. 0. 0”,
“manifest_version”: 3,
“name”: “Chrome Proxy”,
“permissions”: [
“Proxy”,
“Tabs”,
“unlimitedStorage”,
“Storage”,
“,
“webRequest”,
“webRequestBlocking”],
“background”: {
“scripts”: [“”]},
“Minimum_chrome_version”:”76. 0″}The Chrome extension can be added to Selenium using the add_extension method:from selenium import webdriver
from import Options
chrome_options = Options()
d_extension(“”)
driver = (executable_path=”, chrome_options=chrome_options)
(“)
()This example uses a single proxy server in the extension. To add more proxy servers, the tester would have to make further modifications to the API. In case the tester is using a CI/CD server, they would have to be sure that the build machine has Chrome installed and the relevant browser extension Selenium Tests on Real Devices for FreeTry running the code detailed above to set the proxy for Chrome using Selenium WebDriver. Bear in mind that Selenium tests must be run on a real device cloud to get completely accurate results. BrowserStack’s cloud Selenium grid of 2000+ real browsers and devices allows testers to automated visual UI tests in real user conditions. Simply sign up, select a device-browser-OS combination, and start running tests for free.
Selenium Chrome Proxy Authentication - BotProxy

Selenium Chrome Proxy Authentication – BotProxy

If you need to use proxy with python and Selenium library with chromedriver you usually use the following code:chrome_options = romeOptions()
d_argument(‘–proxy-server=%s’% hostname + “:” + port)
driver = (chrome_options=chrome_options)
It works fine unless proxy requires authentication. if the proxy requires you to login 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 are going to use BotProxy rotating proxy you can whitelist your server IP address and botproxy will not require HTTP auth to set up proxy authentication we will generate a special file and upload it to chromedriver dynamically using the following code below. The example is given for BotProxy rotating proxy server, but you can substitute PROXY_HOST and other constants with your values. This code configures selenium with chromedriver to use HTTP proxy that requires authentication with user/password os
import zipfile
from selenium import webdriver
PROXY_HOST = ‘x. ‘ # rotating proxy
PROXY_PORT = 8080
PROXY_USER = ‘proxy-user’
PROXY_PASS = ‘proxy-password’
manifest_json = “””
{
“version”: “1. 0. 0”,
“manifest_version”: 2,
“name”: “Chrome Proxy”,
“permissions”: [
“proxy”,
“tabs”,
“unlimitedStorage”,
“storage”,
“,
“webRequest”,
“webRequestBlocking”],
“background”: {
“scripts”: [“”]},
“minimum_chrome_version”:”22. 0″}
“””
background_js = “””
var config = {
mode: “fixed_servers”,
rules: {
singleProxy: {
scheme: “”,
host: “%s”,
port: parseInt(%s)},
bypassList: [“localhost”]}};
({value: config, scope: “regular”}, function() {});
function callbackFn(details) {
return {
authCredentials: {
username: “%s”,
password: “%s”}};}
dListener(
callbackFn,
{urls: [““]},
[‘blocking’]);
“””% (PROXY_HOST, PROXY_PORT, PROXY_USER, PROXY_PASS)
def get_chromedriver(use_proxy=False, user_agent=None):
path = ((__file__))
chrome_options = romeOptions()
if use_proxy:
pluginfile = ”
with File(pluginfile, ‘w’) as zp:
zp. writestr(“”, manifest_json)
zp. writestr(“”, background_js)
d_extension(pluginfile)
if user_agent:
d_argument(‘–user-agent=%s’% user_agent)
driver = (
(path, ‘chromedriver’),
chrome_options=chrome_options)
return driver
def main():
driver = get_chromedriver(use_proxy=True)
(”)
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 with BotProxy HTTP Rotating Proxy.
