用户认证+实例

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)
