Django DRF“；字段是必填的“；POST请求出错？

错误

views.py

{"name":["This field is required."]}%

我知道身份验证是有效的，因为如果我输入了错误的用户或将错误更改传递给“无效凭据”。为什么我会得到字段required错误？

我忘了在POST请求中添加“-H”内容类型：application/json

{"name":["This field is required."]}%

class platform_list(APIView):

    def get(self, request, format=None):
        query = request.GET.get('name')
        if query:
            platforms = Platform.objects.filter(name=query)
        else:
            platforms = Platform.objects.all()
        serializer = PlatformSerializer(platforms, many=True)
        return Response(serializer.data)

    def post(self, request, format=None):
        serializer = PlatformSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
