如何为创建API端点制作能够处理嵌套post数据的自定义序列化程序？

# serializers.py
from rest_framework import serializers

class CustomSerializer(serializers.Serializer):
    def to_representation(self, instance):
        # 递归处理嵌套对象的序列化
        result = {}
        for field_name, field_value in instance.items():
            if isinstance(field_value, dict):
                # 如果字段是字典类型，则递归调用to_representation方法
                result[field_name] = self.to_representation(field_value)
            else:
                result[field_name] = field_value
        return result

    def to_internal_value(self, data):
        # 递归处理嵌套对象的反序列化
        result = {}
        for field_name, field_value in data.items():
            if isinstance(field_value, dict):
                # 如果字段是字典类型，则递归调用to_internal_value方法
                result[field_name] = self.to_internal_value(field_value)
            else:
                result[field_name] = field_value
        return result

# views.py
from django.http import JsonResponse
from .serializers import CustomSerializer

def api_endpoint(request):
    if request.method == 'POST':
        serializer = CustomSerializer(data=request.data)
        if serializer.is_valid():
            serialized_data = serializer.validated_data
            # 处理序列化后的数据
            return JsonResponse(serialized_data)
        else:
            return JsonResponse(serializer.errors, status=400)
