Facebook 帮助|异常：200:用户没有'；t授权应用程序执行此操作

我以前测试过我的应用程序，我成功地将它发布到我的页面上。 但现在，在我更改代码并删除权限并再次登录后，它不起作用，并引发了此异常：

异常：200:用户尚未授权应用程序执行此操作

代码：

if（isset（$\u POST['submit']））{
试一试{
//$facebook=新的facebook（#####，###）；
$facebook->api_client->session_key='#####]//我曾经通过一个教程得到过这个，但是我似乎无法得到一个新的，有没有办法自动得到一个？
$response=$facebook->api（数组）(
'方法'=>'stream.publish'，
'消息'=>'来自dreafmhosters.com的测试'，
“target_id”=>###mypageid###；
));
}捕获（例外$e）{
回声$e.“
”；
}
}
?>

有什么解决方案吗？

代码中有很多问题。代码有点过时了。它不能与新的graph api一起正常工作。目前facebook it正在运行Graph API 3.0.0版。下面是一个示例代码，可以正确地发布到用户的墙上：

<?php
    //facebook application
    //set facebook application id, secret key and api key here
    $fbconfig['appid' ] = "123456392899383";
    $fbconfig['api'   ] = "97eb2asdfasdf3f20d4421b0fe8c1b2";
    $fbconfig['secret'] = "5c1d4asdfasdf71b59806b69c386b2ca";

    //set application urls here
    $fbconfig['baseUrl']    =   "http://www.your-url.com/";
    $fbconfig['appBaseUrl'] =   "http://apps.facebook.com/appname/"; 

    $uid            =   null; //facebook user id

    try{
        include_once "facebook.php";
    }
    catch(Exception $o){
        echo '<pre>';
        print_r($o);
        echo '</pre>';
    }
    // Create our Application instance.
    $facebook = new Facebook(array(
      'appId'  => $fbconfig['appid'],
      'secret' => $fbconfig['secret'],
      'cookie' => true,
    ));

    //Facebook Authentication part
    $session = $facebook->getSession();
    $loginUrl = $facebook->getLoginUrl(
            array(
            'canvas'    => 1,
            'fbconnect' => 0,
            'req_perms' => 'email,publish_stream,status_update,user_birthday,user_location,user_work_history'
            )
    );

    $fbme = null;

    if (!$session) {
        echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
        exit;
    }
    else {
        try {
            $uid      =   $facebook->getUser();
            $me     =   $facebook->api('/me');
    $uid      =   $facebook->getUser();
    $me     =   $facebook->api('/me');
    $message_details = array(
    'message'=> 'Friends if you see this post, dont click/comment/like it. This is UNDER DEVELOPMENT',
    'link'=> 'http://apps.facebook.com/appurl',
    'name'=> 'Application Name',
    'picture'=> 'http://www.yoururl.com/image.jpg',
    'actions'=> array('name'=>'use Application','link'=>'http://apps.facebook.com/appurl'),
    'description'=> 'A FB application under development by me.',
);
$upload_message = $facebook_client->api('/feed', 'post', $message_details);
        } catch (FacebookApiException $e) {
            echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
            exit;
        }
    }

    function d($d){
        echo '<pre>';
        print_r($d);
        echo '</pre>';
    }
?>

1首先（我使用了这个图吗？）2它抛出了一个异常：致命错误：在www.myurl.com/index2.php的第30行调用未定义的方法Facebook:：getSession（），我不明白你的意思。
