如何重写APIView中的get_serializer_class以根据特定条件更改基于类的视图中的serializer_class属性。

from rest_framework.views import APIView
from rest_framework.response import Response

class MyAPIView(APIView):
    def get_serializer_class(self):
        if self.request.method == 'GET':
            return MyGetSerializer
        elif self.request.method == 'POST':
            return MyPostSerializer
        else:
            return MyDefaultSerializer

    def get(self, request):
        serializer = self.get_serializer()
        # 其他处理逻辑
        return Response(serializer.data)

    def post(self, request):
        serializer = self.get_serializer()
        # 其他处理逻辑
        return Response(serializer.data)

    def put(self, request):
        serializer = self.get_serializer()
        # 其他处理逻辑
        return Response(serializer.data)
