DRF:仅用于表示目的。如何组合两个序列化程序

from rest_framework import serializers

class Serializer1(serializers.Serializer):
    field1 = serializers.CharField()
    field2 = serializers.CharField()

class Serializer2(serializers.Serializer):
    field3 = serializers.CharField()
    field4 = serializers.CharField()

class CombinedSerializer(serializers.Serializer):
    serializer1_data = Serializer1()
    serializer2_data = Serializer2()

    def to_representation(self, instance):
        data = super().to_representation(instance)
        return {
            'serializer1_data': data['serializer1_data'],
            'serializer2_data': data['serializer2_data']
        }

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

class MyView(APIView):
    def get(self, request):
        serializer = CombinedSerializer()
        data = {
            'serializer1_data': {
                'field1': 'value1',
                'field2': 'value2'
            },
            'serializer2_data': {
                'field3': 'value3',
                'field4': 'value4'
            }
        }
        serialized_data = serializer.to_representation(data)
        return Response(serialized_data)
