需要用到的模块
- 系统用户模块
from django.contrib.auth.models import AbstractUser
- 用户登录校验模块
from django.contrib.auth.decorators import login_required
- 用户验证模块
from django.contrib import auth
装饰器
login_required- 作用
- 用来装饰路由函数,当用户未登录的时候,跳转到指定的页面
- 跳转页面设置
LOGIN_URL = '/index/login/'在settings中添加
认证模块功能
- 用户登录认证
user = auth.authenticate(username=uname, password=upwd)
- 封装登录session
auth.login(request, user)
- 普通用户注册
User.objects.create_user(username=uname, password=upwd)
- 用户注销
auth.logout(request)
