1.如果需要实现在定义路由条目时，请求方法与要调用的action方法进行一一对应，必须得继承ViewSetMixin
2.ViewSet继承了ViewSetMixin、APIView，具备请求方法与要调用的action方法进行一一对应功能、以及认证授权限流功能，但是不支持Mixin，因为没有提供get_object()、get_queryset()、geat_serializer()等方法
3.GenericViewSet继承了ViewSetMixin、GenericAPIView，具备请求方法与要调用的action方法进行一一对应功能、以及支持Mixin拓展类
4.ReadOnlyModelViewSet继承了RetrieveModelMixin、ListModelMixin、GenericViewSet，提供了读取数据的2个接口
5.ModelViewSet继承了CreateModelMixin、RetrieveModelMixin、UpdateModelMixin、DestroyModelMixin、ListModelMixin、GenericViewSet，提供了6个接口
6.ViewSetMixin类提供了请求方法与要调用的action方法进行一一对应功能，在定义路由条目时，在as_view()方法中支持接收字典数据，把请求方法名称字符串作为key，把具体要调用的action方法名字符串作为值"""# class RetrieveAPIView(mixins.RetrieveModelMixin, GenericAPIView):
