Postman API 删除功能问题

Question

我在网址中有以下内容：

path('api/delete/<int:pk>/', views.Person.as_view())

我正在使用邮递员进行测试，我是新手。在查询参数中，我输入

pk as the key and 4 as the value 

选择删除并 ...:8000/api/delete/?pk=4/

我收到 404 HTTP 错误，提示 Not found: /api/delete/

这是我的删除功能。

def delete(self, request, pk):
    print('inside delete')
    person = self.get_object(pk)
    print(person)
    person.delete()
    person.save()
    return Response(status = status.HTTP_204_NO_CONTENT)

它永远不会进入删除，这表明我的路径有问题。

谢谢

查看：

class Person(APIView):

    def get_object(self, pk):
        try:
            print('inside get object')
            return Person.objects.get(pk = pk)
        except Person.DoesNotExist:
            raise Http404

    def get(self, request, pk):
        print('inside get')
        person = self.get_object(pk)
        serializer = PersonSerializer(person)
        return Response(serializer.data)

    def delete(self, pk):
        print('inside delete')
        person = self.get_object(pk)
        print(person)
        person.delete()
        return Response(status = status.HTTP_204_NO_CONTENT)

您应该向127.0.0.1:8000/api/delete/4/ 发出DELETE 请求（注意尾部斜杠）
