Django Rest Framework，无法发布数据

Question

我正在尝试获取用户发布的数据，并在保存之前解析它。这是我正在使用的代码，但我不明白为什么它不起作用。

Serializers.py

class MobileDataSerializer(serializers.Serializer):

   m = serializers.IntegerField()
   o = serializers.CharField(max_length=50)
   c = serializers.CharField(max_length=50)
   um = serializers.CharField(max_length=1000, blank=True)
   cm = serializers.CharField(max_length=1000, blank=True)
   p1 = serializers.CharField(max_length=1000, blank=True)


   def restore_object(self, attrs, instance=None):

       if instance:
          instance.m = attrs.get('m', instance.m)
          instance.o = attrs.get('o', instance.o)
          instance.c = attrs.get('c', instance.c)
          instance.um = attrs.get('um', instance.um)
          instance.cm = attrs.get('cm', instance.cm)
          instance.p1 = attrs.get('p1', instance.p1)
          return instance

我的views.py看起来像这样。

@api_view(['POST'])
def data_items(request):
   print("test")
   if request.method == 'POST':
       serializer = MobileDataSerializer(data=request.DATA)
       print(serializer.data)
       if serializer.is_valid():
           #print(serializer)
           return Response(serializer.data, status=status.HTTP_201_CREATED)
       else:
           return Response(
               serializer.errors, status=status.HTTP_400_BAD_REQUEST)

要执行POST请求，我使用以下命令：

curl -X POST http://127.0.0.1:8000/api/network18/ -d "m=1231212&o=afaadas&c=asdasdasd"

我得到的回应是：

{"m": 0, "o": "", "c": "", "um": "", "cm": "", "p1": ""}
