APIView 常规用法

from rest_framework.views import APIView
from .models import Category
from .serializers import CategorySerializer
from rest_framework.response import Response


class ListView(APIView):
    def get(self, request):
        categories = Category.objects.all()
        serializer = CategorySerializer(categories, many=True)
        return Response(serializer.data)

配置路由

urlpatterns = [
    path('', views.ListView.as_view(), name='list'),
]
```...
