Question

我正在使用django rest框架来实现一个简单的api。在我的view.py里面我有这个方法：

def business_profile_detail(request, pk):
    """
    Retrieve, update or delete a profile.
    """
    try:
        profile = BusinessProfile.objects.get(pk=pk)
    except BusinessProfile.DoesNotExist:
        return HttpResponse(status=404)

    if request.method == 'GET':
        serializer = BusinessProfileSerializer(profile)
        return JSONResponse(serializer.data)

    elif request.method == 'PUT':
        """
        Method not supported yet
        """
        return Response(status=status.HTTP_405_METHOD_NOT_ALLOWED)

    elif request.method == 'DELETE':
        """
        Method not supported yet
        """
        return Response(status=status.HTTP_405_METHOD_NOT_ALLOWED)

因此，对于PUT和DELETE方法，我想返回错误405，但是使用django测试服务器，我一直收到错误500：

[17/Oct/2014 18:20:22] "DELETE /business/api/profile/2 HTTP/1.1" 500 60487

任何人都知道为什么？

谢谢！

看起来你在那里使用的Response类需要一个数据参数：

签名：Response(data, status=None, template_name=None, headers=None, content_type=None)

http://www.django-rest-framework.org/api-guide/responses

我只是在那里使用基本HttpResponse。

Django服务器返回不同的状态代码
