这篇文章主要介绍了Django rstful登陆认证并检查session是否过期代码实例，下面我们可以来一起学习一下。

一：restful用户视图

#!/usr/bin/env python# -*- coding:UTF-8 -*-# Author:Leslie-xfrom users import modelsfrom rest_framework.decorators import actionfrom rest_framework.response import Responsefrom rest_framework import viewsetsfrom rest_framework import serializersfrom django.contrib.auth import authenticate, login, logoutclass UserSerializer(serializers.ModelSerializer):  class Meta:    model = models.User    exclude = ('password',)class UserViewSet(viewsets.ReadOnlyModelViewSet):  serializer_class = UserSerializer  queryset = User.objects.all()  authentication_classes = (UserAuthentication,)  @action(detail=False, methods=['post'])  def register(self, request, *args, **kwargs):    username = request.data.get("username")    queryset = User.objects.filter(username=username)    if queryset.exists():      raise exceptions.PermissionDenied('该账号已经被注册')    user = User.objects.create_user(**request.data)    UserProfile.objects.create(user=user, nickname=user.username)    data = self.get_serializer(user).data    return Response(data)  @action(detail=False, methods=['post'])  def login(self, request, *args, **kwargs):    username = request.data.get("username")    password = request.data.get("password")    user = authenticate(username=username, password=password)    if not user:      raise exceptions.PermissionDenied('用户名或密码错误')    auth_id = request.session.get('_auth_user_id')    if auth_id != str(user.pk):      logout(request)    login(request, user)    data = self.get_serializer(user).data    data['session_key'] = request.session.session_key    return Response(data)  @action(detail=False, methods=['post'])  def logout(self, request, *args, **kwargs):    logout(request)    return Response()

二：检查session是否过期

from rest_framework.authentication import SessionAuthenticationfrom rest_framework.request import Requestfrom django.contrib.sessions.models import Sessionfrom rest_framework import exceptionsimport arrowclass CustomAuth(SessionAuthentication):  def check_session(self, request):    session_key = request.session.session_key    queryset = Session.objects.filter(session_key=session_key)    if not queryset.exists():      raise exceptions.PermissionDenied('非法用户，拒绝访问')    expire_date = queryset.first().expire_date    now = arrow.now().format('YYYY-MM-DD HH:mm:ss')    if not arrow.get(now) < arrow.get(expire_date):      raise exceptions.PermissionDenied('session expired')  def authenticate(self, request: Request):    ret = super().authenticate(request)　　　　 self.check_session(request)　　　　 return ret
