如何使用Selenium和Python更改用户代理 [英] How to change the User Agent using Selenium and Python

问题描述

在使用Selenium的Python中更改Web驱动程序用户代理时出现错误.

I am having an error when changing the web driver user agent in Python using selenium.

这是我的代码:

import requests
import json
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
#Error is on line above

这是我的错误:

>>> driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"}) 
  File "<stdin>", line 1
    driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"})```

推荐答案

您的代码只是完美.您只需编写代码行即可更改 user-agent 在下一行中.例如:

Your code is just perfect. You simply have to write the line of code to change the user-agent in the next line. As an example:

• 代码块:

• Code Block:

from selenium import webdriver

driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.97
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
# Setting user agent as Chrome/83.0.4103.53
driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36'})
print(driver.execute_script("return navigator.userAgent;"))
driver.get('https://www.httpbin.org/headers')
