python - json解析django rest框架

Question

我想在 django views.py 文件中解析传入的 POST 数据

POST 数据:

{
"number" : "17386372",
"data" : ["banana","apple","grapes" ]  
}

下面是我尝试使用 request

读取上述传入数据的方式

View .py

class Fruits(APIView):

def post(self, request, format=None):

   if request.method == "POST":

        number = request.data.get('number')
        fruits_data = json.loads(request.body)

        if number not in [None, '', ' ']:
            try:

                response = {"return": "OK","data":fruits_data['data']}
                return Response(response)
            except:
                return Response({"return": "NOT OK"})
        else:
            return Response({"return": "NOT OK"})

    else:
        return Response({"return": "NOT OK"})

错误:

You cannot access body after reading from request's data stream

Django json 解析器已经为您做了这些:

from rest_framework import parsers

class Fruits(APIView):
    parser_classes = (parsers.JSONParser,)

    def post(self, request, format=None):
        number = request.data['number']
        fruits = request.data['data']

如果您的 http 请求的 Content-Type 已经正确设置为 application/json，您甚至不需要指定解析器。
