如何使用 Selenium 和 Python 更改用户代理

Question

我在使用 selenium 更改 Python 中的 Web 驱动程序用户代理时遇到错误。

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"})
  文件“<stdin>”，第 1 行
    driver = webdriver.Chrome(driver_path) driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent":"python 3.7", "platform":"Windows"})```

Answer 1

你的代码非常完美。您只需编写一行代码来更改下一行中的用户代理。举个例子：

• 代码块：

  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')
  

• 控制台输出：

  Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36
  Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36
  Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.53 Safari/537.36
