1、QQ互联（链接地址：https://connect.qq.com/index.html），进行开发者认证（未认证的情况下），有公司和个人两种认证方式，个人开发者选择个人认证就好，准备好身份证电子版。认证界面如图一，认证不做赘述。
（图一）
2、认证通过界面如图二，认证完，我们将创建应用如图三，选择创建网站应用，填写好个人信息如图四。
（图二）
（图三）
（图四）
3、应用创建好后，会有大约2天的认证时间，认证通过的情况下，可在应用管理下查看。成功创建的应用如图五
（图五）
4、代码部分，tp3.2版本，新建QqController.class.php，名称自拟，但是需要符合你的回调地址。
