Facebook登录PHP SKD

任务：从我的网站成功登录Facebook，返回用户ID，并最终通过电子邮件等方式添加到我的数据库中

我从developers.facebook.com下载了最新的4.0.0 SKD PHP，并将其上传到我的文件管理器

我正在使用GitHub上的代码：

请参见

index.php上的下面代码

<?

/* INCLUSION OF LIBRARY FILEs*/
    require_once( 'lib/Facebook/FacebookSession.php');

    //1.Stat Session
     session_start();

     //2.Use app id,secret and redirect url 
    $app_id = 'my id';
     $app_secret = 'my secret';
     $redirect_url='my url';

     //3.Initialize application, create helper object and get fb sess
     FacebookSession::setDefaultApplication($app_id,$app_secret);
     $helper = new FacebookRedirectLoginHelper($redirect_url);
     $sess = $helper->getSessionFromRedirect();
    //4. if fb sess exists echo name 
        if(isset($sess)){
            //create request object,execute and capture response
        $request = new FacebookRequest($sess, 'GET', '/me');
        // from response get graph object
        $response = $request->execute();
        $graph = $response->getGraphObject(GraphUser::className());
        // use graph object methods to get user details
        $name= $graph->getName();
        echo "hi $name";
    }else{
        //else echo login
        echo '<a href='.$helper->getLoginUrl().'>Login with facebook</a>';
    }

    ?>

在查看了here和Google之后，我似乎无法找到这个错误的原因以及如何修复它。
设法找到了答案

我想我会把它贴在这里，让其他人知道谁可能在挣扎

非常简单

确保重定向url的末尾有一个/
