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-8from django.shortcuts import render,render_to_response# Create your views here.from django.http import HttpResponsefrom UserClass import UserLogindef 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 myReponsedef 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。
