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。
