基于Thinkphp3.2的qq第三方认证登录扩展类，其实以下类也是我从TP官网收集整理得来的，稍微做了一下修改和完善。
这里我将文件放存在“/Application/Common/Lib/Qqconnect.class.php”。（其实这个文件路径根据自己喜好来放）
实例化
$Qqconnect = new CommonLibQqconnect();
在__construct方法中你可以直接写你的app_id、app_key和回调地址
也可以根据自己的喜好，改一下代码传参或者写到配置文件。
立即学习“PHP免费学习笔记（深入）”；
调用方法：
1. 在qq的登录按钮的方法中调用getAuthCode方法
$qqobj=new OrgUtilQqconnect();$qqobj->getAuthCode();
2.在回调地址的方法中调用getUsrInfo方法
$qqobj=new OrgUtilQqconnect();$result=$qqobj->getUsrInfo();
3.getAuthCode方法中的参数scope根据自身需要添加值get_user_info,list_album,upload_pic,do_like。

下面是控制器中的代码
LoginController.class.php该文件主要包含两个方式
点击QQ登陆的时候访问的地址
public function qq_login(){ $Qqconnect = new CommonLibQqconnect(); $Qqconnect->getAuthCode(); }
回调访问地址
public function callback(){ $Qqconnect = new CommonLibQqconnect(); $openid = $Qqconnect->getOpenId(); $qq = session('qq'); $Member = M('Member'); $map = array(); $map['openid'] = $openid; $userInfo = $Member->where($map)->find(); if(!empty($userInfo)){ $this->success('登陆成功！',U('Member/index')); }else{ $Qqconnect = new CommonLibQqconnect(); $userInfo = $Qqconnect->getInfo($qq['openid'],$qq['access_token']); print_r($userInfo); exit; }
以上只是简单的示例，大家可以参考一下再进行修改和完善。如有不明白的地方可以留言讨论。
