    这是一个创建于 2090 天前的主题,其中的信息可能已经有所发展或是发生改变。
    import selenium
    from selenium import webdriver
    from fake_useragent import UserAgent

    ua = UserAgent()
    option = webdriver.ChromeOptions()
    option.add_argument('--headless')
    option.add_argument("window-size=1024,768")
    option.add_argument('--start-maximized')
    option.add_argument('user-agent="%s"'%ua.random)
    browser = webdriver.Chrome(executable_path=r'E:\selenium\chromedriver.exe', chrome_options=option)
    browser.get('https://www.baidu.com')
    browser.save_screenshot(r'D:\ok.png')


    chromedriver 在 headless 模式下运行会产生大量的日志信息, 请问如何屏蔽, 日志信息如下:

    λ python demo.py

    尝试指定日志文件(路径)
    options.addArguments("log-path=chromedriver.log");


    options.addArguments("log-path=/dev/null");

    将日志等级设定为 3 即可
    chrome_options.add_argument('log-level=3')
    #info(default) = 0
    #warning = 1
    #LOG_ERROR = 2
    #LOG_FATAL = 3
