php - 与XF \ Pub \ Controller \ AbstractController相关的TypeError

免责声明：我是XenForo 2.X编程的新手，请放心。

An exception occurred: [TypeError] Argument 1 passed to 
Pages\Providers::getData() must be an instance of 
XF\Pub\Controller\AbstractController, string given in 
src/addons/Pages/Providers.php on line 23

我不知道自己在做什么错...这是我目前的攻击计划，我有很短的代码片段（下面包含一个函数），我想在XenForo页面中调用它使用PHP回调。回调的条件是使用控制器和xf所述的回复引用：

\XF\Pub\Controller\AbstractController $controller控制器实例。由此您可以检查请求，响应等。
\XF\Mvc\Reply\AbstractReply &$reply页面的标准回复控制器。

页面节点中包含的回调为Pages\Providers::getData()。但是这样运行给我TypeError。据我了解，$controller参数1不是正确类型，但又如何呢？我的代码甚至不需要它。关于如何解决这个问题的任何想法将不胜感激！谢谢。

<?php

namespace Pages;

class Providers
{
    /**
     * @param \XF\Pub\Controller\AbstractController $controller
     * @param \XF\Mvc\Reply\AbstractReply           &$reply
     */
    public static function getData(
        \XF\Pub\Controller\AbstractController $controller,
        \XF\Mvc\Reply\AbstractReply &$reply
    ) {
        if ($reply instanceof \XF\Mvc\Reply\View) {
                $finder = \XF::finder('XF:Thread');
                $thread = $finder->where('thread_id', 1)->fetchOne();
                $firstPost = \XF::app()->finder('XF:Post')->where('post_id', $thread['first_post_id'])->fetchOne();
                $viewParams = [
                    'title' => $thread['title'],
                    'message' => $firstPost['message']
                ];

                // return $firstPost['message'];
                $reply->setParam('providers', $viewParams);
        }
    }
}
