djiango的中间件不知道为什么没生效

照着教程想写个简易的django登录验证试试中间件，也在settings里注册过了，之前简单试了一下确认了是有用的（不是这个登录验证),但是改成登录验证后无论是已登录还是未登录的判定都没生效(有cookies和清除cookies)，也就是没有返回httpresponse
下图是我写的代码

下图是教程里的代码

函数名是固定的，你写的不对，应该是process_request，你写的process_requset

有帮助的话，请点采纳该答案~

• 这篇博客: Django的cookie缓存以及set_cookie中文格式问题中的 使用set_cookie做用户登录记住用户名时，用户名为中文时，报了错误。 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

  解决方法：
  用json.dumps(value)成功。
  需要用到cookie中的内容时再 json.loads(value)就可以
