Errors in ChromeDriver logs using a proxy through Selenium and Python

Question

I am trying to test how to use proxies using selenium in python Here's the code I am trying

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import time

PROXY = "164.68.123.119:9300"
opts = Options()
#opts.add_argument('--proxy-server=%s' % PROXY)
driver = webdriver.Chrome(executable_path="D:/Webdrivers/chromedriver.exe", options=opts)

print(type(driver))
driver.get("https://www.google.com")
myPageTitle=driver.title
print(myPageTitle)
assert "Google" in myPageTitle
time.sleep(10)
print(driver.quit)
driver.quit()

When running the code without relying on the proxy, I got error logs like that

Any idea how to fix such errors?

Answer 1

To initiate Chrome browser using a proxy you can try the following solution:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

PROXY = "164.68.123.119:9300"
options = Options()
options.add_argument('--proxy-server={}'.format(PROXY))
options.add_argument("start-maximized")
driver = webdriver.Chrome(executable_path=r'C:\WebDriver\ChromeDriver\chromedriver.exe', options=options)
print(type(driver))
driver.get("https://www.google.com")
myPageTitle=driver.title
print(myPageTitle)
assert "Google" in myPageTitle
time.sleep(10)
driver.quit()

PS: chrome_browser_main_extra_parts_metrics.cc , device_event_log_impl.cc , usb_descriptors.cc , etc are the result of a generic bug due to Chrome/ChromeDriver compatibility which you can ignore as of now. For details check Parametrized tests are flaky due to a timeout in recording expensive metrics on startup .
