Cakephp3自定义ExceptionRenderer

Question

我正在尝试为错误404构建自定义异常渲染器。我修改了配置，如下所示：

app.php

'Error' => [
        'errorLevel' => E_ALL,
        'exceptionRenderer' => 'App\Error\AppExceptionRenderer', // use my custom renderer
        'skipLog' => [],
        'log' => true,
        'trace' => true,
    ],

并创建以下脚本：

src / Error / AppExceptionRenderer.php

<?php
namespace App\Error;

use App\Controller\SiteHomepageController;
use Cake\View\View;
use Cake\Event\Event;
use Cake\Error\ExceptionRenderer as ExceptionRenderer;
use Cake\Network\Exception\NotFoundException as Exception;

class AppExceptionRenderer extends ExceptionRenderer {

  protected function _getController(){
    $controller = new SiteHomepageController(null,null,null);
    return $this->controller=$controller;
  }

  public function _template(Exception $exception, $method, $code)
  {
    $template = 'error';
    return $this->template = $template;
  }

  public function render(){

    $exception = $this->error;
    $code = $this->_code($exception);
    $method = $this->_method($exception);
    $template = $this->_template($exception, $method, $code);

    $this->controller->public=true;
    $this->controller->viewBuilder()->layout('site');
    $this->controller->viewBuilder()->templatePath('SiteHomepage');
    $this->controller->set('sez','');
    $this->controller->initialize();
    $this->controller->render($template);

    $event = new Event('');
    $this->controller->afterFilter($event);

    $this->controller->response->statusCode($code);

    return $this->controller->response;

  }

}

但是我收到以下错误：

严格（2048）： App \\ Error \\ AppExceptionRenderer :: _ template（）的声明应与Cake \\ Error \\ ExceptionRenderer :: _ template（Exception $ exception，$ method，$ code）兼容[APP / Error / AppExceptionRenderer.php，行10]

我无法弄清楚自己在做什么以及如何解决问题。 有什么建议么？

我解决了这个问题：

在src / Error / AppExceptionRenderer.php中

我更换：

use Cake\Network\Exception\NotFoundException as Exception;

与：

use Exception;

而且有效！
