Zend Framework 3 中处理内部服务器错误、Mysql 错误（错误处理）的完美方法

Question

我想在 zend 框架中进行异常处理。我需要提供带有状态码的友好错误作为在发生错误时的响应。 这是我的模块。php 我只收到 controller 路由错误，但在 catch 块中没有其他任何内容，我在 module.php 中添加了这个仅一个特定模块

namespace Application;

use Zend\Mvc\ModuleRouteListener;

        $moduleRouteListener->attach($eventManager);


            $application = $e->getApplication();

    $eventManager->attach(MvcEvent::EVENT_DISPATCH_ERROR, [$this, 'catchError']);
    $eventManager->attach(MvcEvent::EVENT_RENDER_ERROR, [$this, 'catchError']);


    }

    public function handleError(MvcEvent $e)
{

    //get the exception
    $exception = $e->getParam('exception');
    //...handle the exception... maybe log it and redirect to another page, 
    //or send an email that an exception occurred...
}

public function catchError(MvcEvent $event) {
    $exception = $event->getParam('exception');
    echo "Exception: ".$exception;
  }
