以Thinkphp3.2为基础的QQ第三方认证登录扩展类

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。

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, 5);
        if (!empty($options)){
            curl_setopt_array($ch, $options);
        }
        $data = curl_exec($ch);
        curl_close($ch);
        return $data;
    }
 
 
    //CURL POST
    private function postUrl($url,$post_data){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        ob_start();
        curl_exec($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。
