python 全栈开发，Day97(Token 认证的来龙去脉,DRF认证,DRF权限,DRF节流)

1. 五个葫芦娃和三行代码
APIView(views.View)
    1. 封装了Django的request
        - request.query_params  --> 取URL中的参数
        - request.data          --> 取POST和PUT请求中的数据
        
    2. 重写了View中的dispatch方法
        dispatch方法
通用类(generics)
    GenericAPIView
        - queryset
        - serializer_class

混合类（mixins）
    - ListModelMixin       --> list     
    - CreateModelMixin     --> create
    - RetrieveModelMixin   --> retrieve
    - DestroyModelMixin    --> destroy
    - UpdateModelMixin     --> update

    CommentView(GenericAPIView, ListModelMixin, CreateModelMixin):
        def get():
            return self.list()
            
        def post():
            return self.create()
        
偶数娃：
    CommentView(ListCreateAPIView):
        queryset = ...
        serializer_class = ...

奇数娃
    CommentDetail(RetrieveUpdateDestroyAPIView):
        queryset = ...
        serializer_class = ...

套娃：
    Comment(ModelViewSet):
        queryset = ...
        serializer_class = ...
