python+selenium利用cookie记住密码

先上代码

 1 from selenium import webdriver
 2 from time import sleep
 3 
 4 dr = webdriver.Chrome()
 5 dr.get("https://www.cnblogs.com/")
 #导入cookie
 6 cookies =[

代码中的cookie如何生成的呢？

利用cookie复制工具复制所有的cookie

不过需要注意的是全部复制出来的会报false或者true未定义，只需要将的未定义的false或者true的那一行删除掉或者改成首字母大写。

如果出现以下错误：

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: invalid 'sameSite'
  (Session info: chrome=80.0.3987.106)

解决方案：

直接遍历pop掉sameSite参数即可。这样添加就不会报错

或者最后一段代码改成：

1 for cook in cookies:
2     #遍历删除sameSite,注意，旧版chrome可能是没有samesite
3     try:
4         cook.pop('sameSite')
5     except:
6         pass
7     dr.add_cookie(cook)
8 dr.refresh()
