Kount+Laravel集成:什么是Kount命名空间/类?

我正在努力将Kount与我的Laravel应用程序集成。我已经使用安装了PHP SDK composer require kount/kount-ris-php-sdk:* ,但当我在签出控制器中使用它时,我不知道导入它时要使用什么命名空间/类名:

<?php

namespace App\Services;

use ??????????

class KountService
{
    public function inquiry(array $data)
    {
        // Minimal RIS inquiry example:
        try {
            $inquiry = new Kount_Ris_Request_Inquiry();
            ....
        }
        ...
    }
}

文件位于 ./vendor/kount/kount-ris-php-sdk ,其中一个(vendor\kount\kount-ris-php-sdk\src\kount\ris\Request\Inquiry.php)包括类 Kount_Ris_Request_Inquiry :

<?php
/**
 * Inquiry.php file containing Kount_Ris_Request_Inquiry class.
 */

/**
 * Perform an initial inquiry request (MODE 'Q' or 'P') to RIS.
 * Contains specific methods for setting various inquiry properties.
 *
 * @package Kount_Ris
 * @subpackage Request
 * @author Kount <[email protected]>
 * @version $Id$
 * @copyright 2012 Kount, Inc. All Rights Reserved.
 */
class Kount_Ris_Request_Inquiry extends Kount_Ris_Request
{
    ...
}

所以我试过了 use Kount\Kount_Ris\Request 和 use Kount\Kount_Ris\Request as Kount_Ris_Request_Inquiry ,但两者都不起作用。
