detail = '%s - %s - %s' % (context.get('view'), context.get('request').method, exc)
if not response: # 服务端错误
response = Response({'detail': detail})
else:
response.data = {'detail': detail}
return response

def get(self,request,*args,**kwargs):
print(request.method)
print(request._request.method)
return Response(data={"msg":"apiview get ok"},status=200)

def post(self,request,*args,**kwargs):
    return Response({
        "msg":"apiview post ok"
    })

class APIResponse(Response):

data = {
'status': data_status,
'msg': data_msg,

if results is not None:
data['results'] = results
data.update(kwargs)
super().__init__(data=data, status=http_status, headers=headers, exception=exception)

class CarAPIView(APIView):
def get(self,request,*args,**kwargs):
return APIResponse(data={"msg":"apiview get ok"})
