Django框架用户注销功能实现方法分析

本文实例讲述了Django框架用户注销功能实现方法。分享给大家供大家参考,具体如下:

HttpResponse()里有个delete_cookie()方法专门用来删除cookie

我们到此来完整的实现一下:访问首页如果没有登录,就跳转到登录页面,登录成功之后再跳转回来的过程。

3个方法,index、login、logout

# coding:utf-8

from django.shortcuts import render,render_to_response

# Create your views here.

from django.http import HttpResponse

from UserClass import UserLogin

def index(request):

msg = {'username':'guest'}

if request.COOKIES.get('userlogin_username') != None :

msg['username'] = request.COOKIES.get('userlogin_username')

myReponse = render_to_response("index.html",msg)

return myReponse

def login(request):

msg = {'result': ''}

if request.method == 'POST':

getUserName = request.POST.get('username')

getPwd = request.POST.get('pwd')

# 实例化UserLogin类

loginObj = UserLogin(getUserName,getPwd)

if loginObj.isLogin():

myReponse = HttpResponse("<script>self.location='/index'</script>")

myReponse.set_cookie('userlogin_username',getUserName,3600)

return myReponse

else:

msg['result'] = '用户名或密码错误'

myReponse = render_to_response("login.html", msg)

return myReponse

# 用户注销

def logout(request):

r = HttpResponse()

r.delete_cookie('userlogin_username')

r.write("<script>self.location='/index'</script>")

return r

首页模板index.html

<!DOCTYPE html>

<html lang="en">

<head>

<meta charset="UTF-8">

<title>首页</title>

</head>

<body>

<h2>这是首页,当前登录用户是:{{ username }}</h2>

{% ifequal username "guest" %}

<p><a href="/login" rel="external nofollow" >登录</a></p>

{% else %}

<p><a href="/logout" rel="external nofollow" >安装退出</a></p>

{% endifequal %}

</body>

</html>

其中用到了Django的模板语法

希望本文所述对大家基于Django框架的Python程序设计有所帮助。
