我目前有一個 GET 請求，我必須將正文作為引數發送，但在前面，不可能使用正文發出 GET 請求，我想將我的引數作為 URL 中的查詢引數傳遞。如何使用我目前擁有的代碼執行此操作？
我的序列化程式類：
@dataclass
class PlantLinkParams:
plant_id: int
link: str
class LnkPlantPlantByLinkSerializer(serializers.Serializer):
plant_id = serializers.IntegerField()
link = serializers.CharField()
def create(self, validated_data):
return PlantLinkParams(**validated_data)我的視圖類：
class PlantLinkAPIView(APIView):
permission_classes = (AllowAnonymous,)
queryset = LnkPlantPlant.objects.prefetch_related("plant", "plant_associated")
def get(self, request):
params_serializer = LnkPlantPlantByLinkSerializer(data=request.data)
params_serializer.is_valid(raise_exception=True)
params = params_serializer.save()
data = self.getAllPlantAssociatedByLink(params)
serializer = ReadLnkPlantPlantSerializer(instance=data, many=True)
return Response(serializer.data, status=status.HTTP_200_OK)
def getAllPlantAssociatedByLink(self, params: PlantLinkParams):
data = []
queryset = (
LnkPlantPlant.objects.filter(
plant=params.plant_id,
link=params.link,
)
)
for entry in queryset:
data.append(entry)

您可以使用ListAPIView做一些更簡單的事情：
class PlantLinkAPIView(ListAPIView):
permission_classes = (AllowAnonymous,)
serializer_class = ReadLnkPlantPlantSerializer
def get_queryset(self):
# Retrieve the query parameters (?plant_id=xxx&link=yyy)
try:
plant_id = int(self.request.GET.get('plant_id'))
except (ValueError, TypeError):
# Prevents plant_id to be set if not a valid integer
plant_id = None
link = self.request.GET.get('link')
params = {}
if plant_id:
params['plant_id'] = plant_id
if link:
params['link'] = link
# Only filtering the queryset if one of the params is set
if params:
return LnkPlantPlant.objects.filter(**params)
return LnkPlantPlant.objects.all()
你不需要更多的東西來讓你的視圖作業。
