Django 自动登陆验证

基础应用

 1 from django.shortcuts import render, redirect
 2 from django.contrib.auth import authenticate, login, logout  #登入和登出
 3 from django.contrib.auth.decorators import login_required  # 验证用户是否登录
 4 def acc_login(request):
 5     if request.method == "POST":
 6         username = request.POST.get("username")
 7         password = request.POST.get("password")
 8 
 9         user = authenticate(username=username,password=password)  # 类型为<class 'django.contrib.auth.models.User'>
10 
11         if user:
12             login(request,user)  # 验证成功之后登录
13             return  redirect('/api/index/')
14 
15     return render(request, "login.html")
16 
17 @login_required  # 加上这个装饰器就是限制必须登录才能执行这个函数
18 def dashboard(request):
19     print(request.user)
20     return render(request, "index.html")
21 
22 def acc_logout(request):
23     logout(request)  # 登出
24     return redirect("/login")

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <title>Title</title>
 6 </head>
 7 <body>
 8 <h1>欢迎登陆</h1>
 9 <form action="/api/login/" method="post" novalidate>
10     {% csrf_token %}
11     <input type="text" name="username">
12     <input type="password" name="password">
13     <input type="submit" value="提交">
14 </form>
15 </body>
16 </html>

升级版

django里面的自动登陆验证是和admin里面的用户信息进行验证的，想用来验证自己写的models，要改造源码

1 继承from django.contrib.auth.backends import ModelBackend，自定义验证

2 setting文件中设置一下验证引擎
