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 \Common\Lib\Qqconnect();
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。
调用方法：
1. 在qq的登录按钮的方法中调用getAuthCode方法
$qqobj=new \Org\Util\Qqconnect();
$qqobj->getAuthCode();
2.在回调地址的方法中调用getUsrInfo方法
$qqobj=new \Org\Util\Qqconnect();
$result=$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。

ob_start();
curl_exec($ch);
$result = ob_get_contents();
ob_end_clean();
return $result;
}
}
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 \Common\Lib\Qqconnect();
$Qqconnect->getAuthCode();
}
回调访问地址
public function callback(){
$Qqconnect = new \Common\Lib\Qqconnect();
$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 \Common\Lib\Qqconnect();
$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。
