//登陆模块

//+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

//QQ登陆SDK下载地址 http://connect.qq.com/

//申请时填写回调地址 域名/index.php/Login/qq_callback.html

//下载好SDK解压到 /ORG/ 类下目录 或自定的目录

//直接访问SDK下的index.php按提示进行安装

//配置时填写回调地址 域名/index.php/Login/qq_callback.html

//获得权限全打勾,这个可以随便,如果你要发微博关注等就勾上

//配置完了,把API之外的文件与目录删除 我把API改成Connect

//把qqConnectAPI.php 改成 qqConnectAPI.class.php

//引入方法 import('@.ORG.Connect.qqConnectAPI');

//当然用别的方法也一样,由个人喜欢而定哈

//下面根据代码说明 了解QQ登陆的详细原理吧
