我正在通過127.0.0.8000/post/. 我的帖子當然是成功的，因為我能夠看到我在127.0.0.8000成功的基本 URL 中發布的內容，但我在 Django 前端得到以下回應。
AssertionError at /post/
Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>`
在 VS Code 中，我在終端中收到以下錯誤
Internal Server Error: /post/

我的 Views.Py 如下
@api_view(['GET'])
def getData(request):
queryset = Wallet.objects.all()
serializer = WalletSerializer(queryset, many=True, context={'request': request})
return Response(serializer.data)
@api_view(['GET'])
def getSingleData(request,pk):
queryset = Wallet.objects.all(id=pk)
serializer = WalletSerializer(queryset, many=False)
return Response(serializer.data)
@api_view(['POST'])
def postData(request):
serializer = WalletSerializer(data = request.data)
if serializer.is_valid():
serializer.save()
PS我也無法在第二種方法中通過ID獲取個人資料，它不起作用
uj5u.com熱心網友回復：
您應該從您的視圖/API 回傳一個回應實體
@api_view(['POST'])
def postData(request):
serializer = WalletSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data)
return Response(serializer.errors)轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/435522.html
