### **特殊说明：自动化测试工具必须安装驱动程序,否则会报错：** ###

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

谷歌驱动下载：[https://sites.google.com/a/chromium.org/chromedriver/home][https_sites.google.com_a_chromium.org_chromedriver_home]

**驱动版本不匹配错误【最新版的驱动必须匹配最新版的谷歌浏览器】：**

谷歌浏览器参考别人写的：[https://www.cnblogs.com/yoyoketang/p/8078873.html][https_www.cnblogs.com_yoyoketang_p_8078873.html]

谷歌浏览器后台启动配置方法
    
    # 配置谷歌浏览器静默启动【后台启动】
    chrome_options = webdriver.ChromeOptions()
    # 谷歌浏览器headless前面的--可以不加【建议加上,代表命令行参数】
    chrome_options.add_argument('--headless')
    # 一定要把chrome_options配置来构造谷歌浏览器对象【必须匹配对应驱动的路径】
    web_chrome = webdriver.Chrome(executable_path=r"D:\www\KirinProject\path\chromedriver.exe",options=chrome_options)
    web_chrome.get("https://www.baidu.com")
    print(web_chrome.page_source)

火狐浏览器后台启动配置方法：
    
    from selenium import webdriver
    
    firefox_options = webdriver.FirefoxOptions()
    # 注：火狐浏览器headless前面一定要加--,代表命令行参数
    firefox_options.add_argument('--headless')
    webdriver.FirefoxOptions()
    web_firefox = webdriver.Firefox(options=firefox_options)
    web_firefox.get("http://www.baidu.com")
    print(web_firefox.page_source)

### **其他浏览器原理差不多！ ** ###
