vue前端和Django后端如何查询一定时间段内的数据

class CountDownSign(models.Model):
 name = models.CharField(max_length=1000) 
 date = models.DateField() 
 sign = models.CharField(max_length=200) 

class CountDownModelSerializer(serializers.ModelSerializer):
 class Meta:
 model = CountDownSign
 fields = '__all__'

 def create(self, validated_data):
 return CountDownSign.objects.create(**validated_data)

 def update(self, instance, validated_data):
 instance.name = validated_data.get('name', instance.name)
 instance.date = validated_data.get('date', instance.date)
 instance.sign = validated_data.get('sign', instance.sign)
 instance.save()
 return instance

obj = models.CountDownSign.objects.filter(date__range=(start, end))

class CountDownViewSet(ModelViewSet):
 parser_classes = [JSONParser, FormParser]
 """视图集"""
 queryset = models.CountDownSign.objects.all()
 serializer_class = CountDownModelSerializer
 # 搜索
 search_fields = ('id', 'name', 'sign', 'date')
 
 @action(methods=['post'], detail=False)
 def getSE(self, request, *args, **kwargs):
 start = request.data.get('start', None)
 end = request.data.get('end', None)
 if start and end:
  obj = models.CountDownSign.objects.filter(date__range=(start, end))

  if obj:
  ser = CountDownModelSerializer(instance=obj, many=True)
  print(ser.data)
  return JsonResponse({
   'code': '200',
   'msg': '获取数据成功',
   'data': ser.data
  })
  else:
  return JsonResponse({
   'code': '1002',
   'msg': '获取失败',
  })
 else:
  return Response(status=status.HTTP_204_NO_CONTENT)

export function searchCountDown(start, end) {
