以Thinkphp3.2為基礎的QQ第三方認證登入擴充類

基於Thinkphp3.2的QQ第三方認證登入擴充類別

基於Thinkphp3.2的qq第三方認證登入擴充類，其實以下類別也是我從TP官網收集整理得來的，稍微做了一下修改和完善。

這裡我將檔案放存在「/Application/Common/Lib/Qqconnect.class.php」。 （其實這個檔案路徑依照自己喜好來放）

實例化

$Qqconnect = new \Common\Lib\Qqconnect();

在__construct方法中你可以直接寫你的app_id、app_key和回呼位址
也可以依照自己的喜好，改一下程式碼傳參或寫到設定檔。

呼叫方法：

1. 在qq的登入按鈕的方法中呼叫getAuthCode方法

$qqobj=new \Org\Util\Qqconnect();
$qqobj->getAuthCode();

    

#2.在在回呼位址的方法中呼叫getUsrInfo方法

$qqobj=new \Org\Util\Qqconnect();
$result=$qqobj->getUsrInfo();

    

3.getAuthCode方法中的參數scope根據自身需要加值get_user_info,list_album,upload_pic,do_like。

        $result = ob_get_contents();
        ob_end_clean();
        return $result;
    }
}

下面是控制器中的程式碼

LoginController.class.php該檔案主要包含兩個方式

#點選QQ登陸的時候訪問的位址

public function qq_login(){
        $Qqconnect = new \Common\Lib\Qqconnect();
        $Qqconnect->getAuthCode();
    }

   回呼存取位址

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;
    }

以上只是簡單的範例，大家可以參考一下再進行修改和完善。如有不懂的地方可以留言討論。
