soundcloud api php add follower

我正在制作一个页面，您可以在其中使用soundcloud登录并访问下载我的歌曲，只要您在soundcloud上关注我。我有身份验证工作，但无法弄清楚以下部分。我几乎从 soundcloud 开发人员网站复制并粘贴了"喜欢和关注"部分下的示例，它都没有按照应有的方式工作。try catch 使我看起来没有关注我的主帐户（我从测试身份验证步骤中获得了用户 id#），即使我在我的测试帐户上访问 soundcloud，并关注我的主帐户。这是我得到的错误：

Warning:  Missing argument 2 for Services_Soundcloud::put(), called in /my_website/index.php on line 43 and defined in /my_website/Services/Soundcloud.php on line 636

Notice:  Undefined variable: postData in /my_website/Services/Soundcloud.php on line 642

Fatal error:  Uncaught exception 'Services_Soundcloud_Invalid_Http_Response_Code_Exception' with message 'The requested URL responded with HTTP code 404.' in /my_website/Services/Soundcloud.php:941

#2 {main}
  thrown in my_website/Services/Soundcloud.php on line 941

这是 IM 运行的代码：

require_once 'Services/Soundcloud.php';
//session_destroy();
session_start();
$soundcloud = new Services_Soundcloud(client_id, secret_id, redirect_uri)
$authURL = $soundcloud->getAuthorizeUrl();
echo "<pre>";
if (!empty ($_SESSION['token'])){
        $soundcloud->setAccessToken($_SESSION['token']);
} else if(!empty($_GET['code'])){
        try{
                $accessToken = $soundcloud->accessToken($_GET['code']);
                $_SESSION['token'] = $accessToken['access_token'];
                $soundcloud->setAccessToken($_SESSION['token']);
        } catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
                exit($e->getMessage());
        }
} else {
        echo "<a href='".$authURL."'><img border='0' alt='Connect with Soundcloud' src='connect.png'></a>";
}
if (!empty ($_SESSION['token'])){
        // check the status of the relationship
        echo $_SESSION['token'];
        try {
                $soundcloud->get('/me/followings/#######');
        } catch (Services_Soundcloud_Invalid_Http_Response_Code_Exception $e) {
                if ($e->getHttpCode() == '404')
                        print "You are not following user #######'nTrying to follow now'n";
                        $soundcloud->put('/me/followings/#######');
        }
}

是 soundcloud 上的示例是错误的，还是我在获得这些命令之前做错了什么？

另请注意，我的 SoundCloud 对象 init 和 follows/##### 已更改以保护我的信息。
