[Python知识库]python selenium在打开的浏览器中动态调整User Agent

核心代码是：

browser.execute_cdp_cmd('Network.setUserAgentOverride', {
        "userAgent": "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2226.0 Safari/537.36",
        "platform": "Windows"})

使用示例

import time

from selenium import webdriver

if __name__ == '__main__':
    option = webdriver.ChromeOptions()
    option.add_argument('lang=zh_CN.UTF-8')  # 设置
    browser = webdriver.Chrome(chrome_options=option)
    browser.get("https://www.baidu.com")
    print(browser.execute_script("return navigator.userAgent")) # 打印当前的userAgent

    # 动态调整useragent
    time.sleep(3)
    browser.execute_cdp_cmd('Network.setUserAgentOverride', {
        "userAgent": "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2226.0 Safari/537.36",
        "platform": "Windows"})
    print(browser.execute_script("return navigator.userAgent"))
    browser.get("https://www.baidu.com")

打印结果：

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.99 Safari/537.36
Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2226.0 Safari/537.36

第一行是我的chrome原始的header，第二行是修改后的header

并且可以在浏览器的header里看到：
