django REST framework，验证json数据

Question

服务器自带json格式：

{
    "type": "string",
    "object": {
        "lead_id": int,
        "form_name": "string",
        "answers": [
            {
                "lead_id": int,
                "key": "string",
            }
            ...
        ]
    },
    "group_id": int,
    "secret": "string"
}

如何使用 django REST framework 来验证这个 json？

例子：

# serializers.py
from rest_framework import serializers


class VkObjectSerializer(serializers.Serializer):
    """
    is 'object'
    """
    lead_id = serializers.IntegerField()
    group_id = serializers.IntegerField()
    user_id = serializers.IntegerField()
    form_id = serializers.IntegerField()


class VkBaseSerializer(serializers.Serializer):
    """
    Base serializer 
    """
    type = serializers.CharField(max_length=200)

    object = VkObjectSerializer()

    group_id = serializers.IntegerField()
    secret = serializers.CharField(max_length=200)

# view.py
from rest_framework.generics import CreateAPIView
from rest_framework.response import Response
from .serializers import VkBaseSerializer


class VkCallbackView(CreateAPIView):
    serializer_class = VkBaseSerializer

    def create(self, request, *args, **kwargs):
        """
        Method is validate json in view
        """
        valid_ser = self.serializer_class(data=request.data)
        if valid_ser.is_valid():
            return Response('True')
        return Response('False')

有效数据：

>>> valid_ser.data
{
    "type": "str",
    "object": {
        "lead_id": 123,
        "group_id": 12345,
        "user_id": 12352,
        "form_id": 1
    },
    "group_id": 5123,
    "secret": "str"
}
