关于Django中使用cookie的三天免登录代码

创建templates/login.htm

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="/student/login/" method="post">
    {% csrf_token %}
    <p>
        <label>用户名：</label><input type="text" name="sname" value="{{ sname }}">
    </p>
    <p>
        <label>密码：</label><input type="password" name="pwd" value="{{ pwd }}">
    </p>
    <p>
        <input type="checkbox" name="check" value="1">记住密码
    </p>
    <p>
        <input type="submit" value="登录">
    </p>
</form>
</body>
</html>

配置路由

根路由

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('student/',include('stu.urls'))
]

子路由

#coding=utf-8

from django.conf.urls import url

from stu import views

urlpatterns = [
    url('^login/$',views.index_login)
]

创建视图函数

from django.http import HttpResponse
from django.shortcuts import render

# Create your views here.
def index_login(request):
    if request.method == 'GET':
        # 判断request中是否存在'login'对应cookie信息
        if 'login' in request.COOKIES:
            login = request.COOKIES.get('login','').split(',')
            sname = login[0]
            pwd = login[1]
            return render(request,'login.html',{'sname':sname,'pwd':pwd})
        return render(request,'login.html')
    else:
        # 获取请求参数
        sname = request.POST.get('sname','')
        pwd = request.POST.get('pwd','')
        flag = request.POST.get('check','')
        response = HttpResponse()
        # 判断是否登录成功
        if sname == 'lisi' and pwd == '123':
            response.content = '登陆成功'
            # 判断是否需要记住密码
            if flag:
                # 将用户名和密码存放至cookie中
                response.set_cookie('login',sname+','+pwd,max_age=3*24*60*60,
                                    path='/student/login/')
            else:
                # 当不需要记住密码时，需要删除cookie中‘login’对应的数据
                response.delete_cookie('login',path='/student/login/')
        else:
            response.delete_cookie('login', path='/student/login/')
            #重定向
            response.status_code = 302
            response.setdefault('Location','/student/login/')
        return response
