How do I create a random user agent in Python + Selenium?
Solution 1
You have not used the options that's why it doesn't work
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("window-size=1400,600")
from fake_useragent import UserAgent
ua = UserAgent()
user_agent = ua.random
print(user_agent)
options.add_argument(f'user-agent={user_agent}')
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://whoer.net/')
driver.quit()
After that it works, see the console and browser output
Solution 2
A simple way to fake the User Agent would be using the FirefoxProfile()
as follows :
from selenium import webdriver
from fake_useragent import UserAgent
useragent = UserAgent()
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", useragent.random)
driver = webdriver.Firefox(firefox_profile=profile, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get("http://www.whatsmyua.info/")
Result of 3 consecutive execution is as follows :
-
First Execution :

Second Execution :

How do I create a random user_agent in Chrome? I am using fake-useragent. Library here. The printed output is working but when it seems it is not loading into Chrome.
I have tried:
from selenium import webdriver from selenium.webdriver.chrome.options import Options options = Options() options.add_argument("window-size=1400,600") from fake_useragent import UserAgent ua = UserAgent() a = ua.random user_agent = ua.random print(user_agent) options.add_argument(f'user-agent={user_agent}') driver = webdriver.Chrome() driver.get('https://whoer.net/')
This does not print a random output each time.
Printed output:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36
(KHTML, like Gecko) Chrome/41.0.2227.1 Safari/537.36Output user_agent according to whoer.net:
