I need to access a website using selenium and Chrome using python. Below is shortened version of my code.

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service

# PROXY='https://myproxy.com:3128'
PROXY = 'https://username:password@myproxy.com:3128'
proxyuser='username' #this is the proxy user name used in above string
proxypwd='password' #this is the proxy password used in above string


chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--proxy-server=%s' % PROXY)
chrome_options.add_argument("ignore-certificate-errors");

chrome = webdriver.Chrome(options=chrome_options,service=Service(ChromeDriverManager().install()))

chrome.get("https://www.google.com")
while True:
    print('ok')

I am behind a corporate proxy server which requires authentication. I am not sure how to pass login credentials and proxy settings for Install of chromedriver When above code is run without proxy, it works as expected. But it gives error as follows when run using proxy connection:

[WDM] - ====== WebDriver manager ======

Bypassing proxy is not possible because of corporate policies

request("get", url, params=params, **kwargs)

this line in errors i believe is the issue. it seems the driver is not able to determine the new version available on net as the request function here should have proxy settings - i am not able to see the **kwargs values, ideally - i believe, **kwargs should have proxy argument. - i am not sure but.

Answer 1

I have modified the code as follows. essentially i have now used custom download manager and this is worling

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.core.download_manager import WDMDownloadManager
from webdriver_manager.core.http import HttpClient
from selenium.webdriver.chrome.service import Service
from requests import Response
import urllib3
import requests
import os
os.environ['WDM_SSL_VERIFY'] = '0'
capabilities = webdriver.DesiredCapabilities.CHROME
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

PROXY = "https://username:password@myproxy.com:3128"
proxyuser='username'
proxypwd='password'
opt = webdriver.ChromeOptions()
opt.add_argument('--proxy-server=%s' % PROXY)
opt.add_argument("ignore-certificate-errors")

class CustomHttpClient(HttpClient):
    def get(self, url, params=None) -> Response:
        proxies={'http': 'http://username:password@myproxy.com:3128',
         'https': 'http://username:password@myproxy.com:3128',
         }
        return requests.get(url, params,proxies=proxies,verify=False)

http_client = CustomHttpClient()
download_manager = WDMDownloadManager(http_client)
chrome = webdriver.Chrome(service=Service(ChromeDriverManager(download_manager=download_manager).install()),options=opt)

chrome.get("https://www.google.com")
while True:
    print('ok')
