基于Thinkphp3.2的qq第三方oauth认证登录扩展类

基于Thinkphp3.2的qq第三方oauth认证登录扩展类，
由于腾讯oauth sdk写的太多，不能与thinkphp和好的结合，最终想法讲腾讯oauth sdk写成tp的扩展类
先看代码，将代码保存在/library/org/util/Qqconnect.class.php文件中
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
例如：
$qqobj=new \Org\Util\Qqconnect();
$qqobj->getAuthCode();

2.在回调地址的方法中调用getUsrInfo方法
例如：
$qqobj=new \Org\Util\Qqconnect();
$result=$qqobj->getUsrInfo();
就可以了

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。
