last_login 在 Django Rest Framework 中使用 Tokenauthentication 进行身份验证时，字段未更新

Question

我在一个依赖 Django 用户模型和 DjangoRestFramework 下的 TokenAuthentication 的项目中工作

我被要求获取每个用户的上次登录日期时间，我意识到当我调用身份验证 REST 端点时，该字段没有得到更新。

这是众所周知的事实吗？我是否遗漏了一些我必须做的事情，以便在每次调用令牌身份验证时更新该字段？

谢谢

Answer 1

嗯，最后我继承自REST Framework TokenAuthentication，在urls文件中指向它

url(r'^api-token-auth/', back_views.TokenAuthenticationView.as_view()),

View 处理请求并像这样手动调用 update_last_login：

from django.contrib.auth.models import update_last_login

class TokenAuthenticationView(ObtainAuthToken):
    """Implementation of ObtainAuthToken with last_login update"""

    def post(self, request):
        result = super(TokenAuthenticationView, self).post(request)
        try:
            request_user, data = requests.get_parameters(request)
            user = requests.get_user_by_username(data['username'])
            update_last_login(None, user)            
        except Exception as exc:
            return None
        return result

@F.D.F。答案很棒。这是另一种方法。

我们发送 user_logged_in 信号，将调用 update_last_login:

user_logged_in.send(sender=user.__class__, request=request, user=user)

这是一个工作视图（基于使用电子邮件作为 USERNAME_FIELD 的自定义用户模型）：

from rest_framework import parsers, renderers
from rest_framework.authtoken.models import Token
from rest_framework.response import Response
from rest_framework.views import APIView

from django.contrib.auth.signals import user_logged_in
from emailauth.serializers import AuthTokenSerializer, UserSerializer


class ObtainAuthToken(APIView):
    throttle_classes = ()
    permission_classes = ()
    parser_classes = (parsers.FormParser, parsers.MultiPartParser, parsers.JSONParser,)
    renderer_classes = (renderers.JSONRenderer,)
    serializer_class = AuthTokenSerializer

    def post(self, request, *args, **kwargs):
        serializer = self.serializer_class(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.validated_data['user']
        token, created = Token.objects.get_or_create(user=user)
        user_logged_in.send(sender=user.__class__, request=request, user=user)
        return Response({'token': token.key, 'user': UserSerializer(user).data})


obtain_auth_token = ObtainAuthToken.as_view()

您可以在此处找到完整的源代码：Api View with last_login updated

希望这对您有所帮助。

更简洁的方法：

from django.contrib.auth.models import update_last_login
from rest_framework.authtoken.models import Token
from rest_framework.authtoken.views import ObtainAuthToken

class LoginToken(ObtainAuthToken):
    def post(self, request, *args, **kwargs):
        result = super().post(request, *args, **kwargs)
        token = Token.objects.get(key=result.data['token'])
        update_last_login(None, token.user)
        return result

然后设置 urls.py:

url(r'^api-token-auth/', views.LoginToken.as_view()),

我对 Django==2.0.5、django-rest-framework-social-oauth2==1.1.0

的回答

from django.contrib.auth import user_logged_in
from oauth2_provider.models import AccessToken
from rest_framework import status
from rest_framework_social_oauth2.views import TokenView

class MyTokenView(TokenView):
    def post(self, request, *args, **kwargs):
        response = super().post(request, *args, **kwargs)
        if response.status_code == status.HTTP_200_OK:
            token = AccessToken.objects.get(token=response.data['access_token'])
            user = token.user
            user_logged_in.send(sender=type(user), request=request, user=user)
        return response

urls.py:

from django.urls import path

urlpatterns = [
    path('token', MyTokenView.as_view(), name='token'),
]

Answer 5

这是我使用 ViewSet 的解决方案：

views.py:

from rest_framework.authtoken.views import ObtainAuthToken
from rest_framework.authtoken.serializers import AuthTokenSerializer
from rest_framework import viewsets
from django.contrib.auth.models import update_last_login

class LoginViewSet(viewsets.ViewSet):
    """Checks email and password and returns an auth token."""

    serializer_class = AuthTokenSerializer

    def create(self, request):
        """Use the ObtainAuthToken APIView to validate and create a token."""

        ##update last_login
        try:
            user = models.User.objects.get(email = request.data['username'])
            update_last_login(None, user)
        except:
            pass

        return ObtainAuthToken().post(request)

现在只需将此视图集添加到 urls.py:

router.register('login', views.LoginViewSet, base_name="login")

Answer 6

这是 django 3.0.8 的最新代码。
:)
谢谢 F.D.F.!

from django.contrib.auth.models import update_last_login
from rest_framework.authtoken.views import ObtainAuthToken
from django.contrib.auth import get_user_model


class TokenAuthenticationView(ObtainAuthToken):
    """Implementation of ObtainAuthToken with last_login update"""
    
    def post(self, request):
        result = super(TokenAuthenticationView, self).post(request)
        currentUserModel = get_user_model()
        try:
            user = currentUserModel.objects.get(username=request.data['username'])
            update_last_login(None, user)
        except Exception as exc:
            return None
        return result

Answer 7

通过信号实现

from django.dispatch import receiver
from django.db.models.signals import post_save
from django.contrib.auth import user_logged_in

from oauth2_provider.models import AccessToken


@receiver(post_save, sender=AccessToken)
def post_save_access_token(instance, created, raw, **kwargs):
    if not created or raw:
        return
    user_logged_in.send(sender=instance.user.__class__,  user=instance.user)

Answer 8

对于任何使用 knox 进行用户身份验证的人，都需要编辑 api.py 文件并导入 user_logged_in，如下所示

from django.contrib.auth.signals import user_logged_in

之后，在同一 api.py 文件中的 LoginAPI class 中，在 _, token = AuthToken.objects.create(user) 之后添加以下行，如下所示

user_logged_in.send(sender=user.__class__, request=request, user=user)

Answer 9

如果您使用的是用于 Django 的简单 JWT，您可以按照此 link 非常轻松地完成。你只需要添加

SIMPLE_JWT = {
...,
'UPDATE_LAST_LOGIN': True,
...,
}
