python - TokenAuthentication 对象没有属性“get

问题描述

我正在尝试使用包含 django-rest-knox 生成的令牌的授权标头对用户进行身份验证。我还有另外两个身份验证后端。为此，我调用了 knox.auth 中定义的 authenticate() 方法。但是，它返回此错误并且无法对用户进行身份验证：WrappedAttributeError at /login/ 'TokenAuthentication' object has no attribute 'get_user' 如果我为从 TokenAuthentication 继承的类定义 get_user() 方法并改用该类，则会得到修复。有什么我可以修复的，这样我就不必实现它或找出触发这个函数调用的中间件？

视图.py

from django.contrib.auth.models import User
from rest_framework.response import Response
from knox.views import LoginView as KnoxLoginView
from knox.auth import TokenAuthentication

class GetAuthToken(KnoxLoginView):
    permission_classes = [AllowAny]

    def post(self, request,*args, **kwargs):
        user = TokenAuthentication().authenticate(request=request)
        if user:
            return Response(status=200)
        else:
            requestToken = request.data.get('requestToken')
            if not requestToken:
                return Response({'result': 'error'})

            user = User.objects.all().first()
            if user is None:  
                return super().post(request, format=None)
            else:
                login(request, user, backend='knox.auth.TokenAuthentication')
                return super().post(request, format=None)
        return super().post(request, format=None)
