如何监听特定 Controller 的调度事件？目前，我执行以下操作:

Module.php

public function onBootstrap(EventInterface $event) {
    $application = $event->getApplication();
    $eventManager = $application->getEventManager();
    $serviceManager  = $application->getServiceManager();

    $eventManager->attach($serviceManager->get('MyListener'));
}

MyListener.php

class MyListener extends AbstractListenerAggregate {

    public function attach(EventManagerInterface $eventManager) {
        $this->listeners[] = $eventManager->attach(
            MvcEvent::EVENT_DISPATCH, function($event) {
                $this->setLayout($event);
            }, 100
        );
    }

    public function setLayout(EventInterface $event) {
        $event->getViewModel()->setTemplate('mylayout');
    }
}

这会设置所有 Controller 分派(dispatch)的布局。现在我只想在应用程序调度特定 Controller 时设置布局。

最佳答案

就像所有模块都有一个onBootstrap() 方法一样，所有扩展AbstractController 的 Controller 都有一个onDispatch() 方法。

考虑到您想要为单个特定 Controller 应用不同的布局，您可以简单地执行以下操作:

<?php

namespace MyModule\Controller;

use Zend\Mvc\Controller\AbstractActionController; // Or AbstractRestfulController or your own
use Zend\View\Model\ViewModel; // Or JsonModel or your own
use Zend\Mvc\MvcEvent;

class MyController extends AbstractActionController
{
    public function onDispatch(MvcEvent $e)
    {
        $this -> layout('my-layout'); // The layout name has been declared somewhere in your config
        return parent::onDispatch($e); // Get back to the usual dispatch process
    }

    // ... Your actions
}

您可以为每个具有特殊布局的 Controller 执行此操作。对于那些不这样做的人，您不必写任何东西。

如果您经常需要更改布局(例如，您必须处理多个 Controller 而不是单个 Controller )，您可以在 module.php 中附加一个 MvcEvent 以将布局设置代码放在一个地方。

为简单起见，我在这里没有使用自定义监听器，但您也可以使用一个。

<?php

namespace MyModule;

use Zend\Mvc\MvcEvent;

class Module
{
    public function onBootstrap(MvcEvent $e)
    {
        $eventManager = $e -> getApplication() -> getEventManager();
        $eventManager -> attach(
            MvcEvent::EVENT_DISPATCH,
            // Add dispatch error event only if you want to change your layout in your error views. A few lines more are required in that case.
            // MvcEvent::EVENT_DISPATCH | MvcEvent::EVENT_DISPATCH_ERROR
            array($this, 'onDispatch'), // Callback defined as onDispatch() method on $this object
            100 // Note that you don't have to set this parameter if you're managing layouts only
        );
    }

    public function onDispatch(MvcEvent $e)
    {
        $routeMatch = $e -> getRouteMatch();
        $routeParams = $routeMatch -> getParams();
        switch ($routeParams['__CONTROLLER__']) {
            // You may use $routeParams['controller'] if you need to check the Fully Qualified Class Name of your controller
            case 'MyController':
                $e -> getViewModel() -> setTemplate('my-first-layout');
                break;
            case 'OtherController':
                $e -> getViewModel() -> setTemplate('my-other-layout');
                break;
            default:
                // Ignore
                break;
        }
    }

    // Your other module methods...
}
