Zend 2:如何使用自定義控制器配置錯誤?

[英]Zend 2: How to configure errors with custom controller?

我的問題是關於自定義Zend 2中如何處理錯誤。

假設我想自定義布局,以便在控制器中的一個操作中做到這一點:

$layout = $this->layout();
$myNav = new ViewModel(array('nav' => $this->getNav());
$myNav->setTemplate('layout/nav');
$layout->addChild($myNav, 'navigation');

當我將其放入控制器進行常規(即非404)查看時,效果很好。 現在,我已經自定義布局,以便可以執行<?php echo $this->navigation; ?> <?php echo $this->navigation; ?>然后啟動layout/nav.phtml ,一切都正常進行。

現在,假設出現錯誤時我想做完全相同的事情。 我需要能夠在錯誤處理程序將其自身的ViewModel(...)error/404.phtml模板之前以某種方式注入上述代碼。

你是怎樣做的?

我懷疑這就像在module.config.php為服務管理器設置正確的類:

'service_manager' => array(
    'services' => array(
        'error_handler' => 'MyModule\Controller\MyCustomErrorController'
        //and so on...

我該怎么做呢?

更新:

在我的Module.php我附加了MvcEvent::EVENT_DISPATCH_ERROR的方法。 變體A有效,而變體B不起作用。 因此,您不能在此處使用局部變量? 我錯過了一些基本的東西嗎?

變體A

public function onDispatchError(MvcEvent $event)
{
    $sm  = $event->getApplication()->getServiceManager();
    $vm = $event->getViewModel();
    $vm->setVariable('nav', '<h1>test do i work?</h1>');
    //Works
}

變體B

public function onDispatchError(MvcEvent $event)
{
    $sm  = $event->getApplication()->getServiceManager();
    $vm = $event->getViewModel();
    $nav = new ViewModel(array('test'=>'hello there'));
    $nav->setTemplate('layout/simpletest');//contents: <?php echo $this->test; ?>
    $vm->addChild($nav, 'nav');
    //In the template, <?php echo $this->nav; ?> has nothing...
}

Zf2使用module.config.php文件設置錯誤處理:

'view_manager' => array(
        'display_not_found_reason' => true,
        'display_exceptions'       => true,
        'doctype'                  => 'HTML5',
        'not_found_template'       => 'error/404',
        'exception_template'       => 'error/index',
        'template_map' => array(
            'layout/layout'           => __DIR__ . '/../view/layout/layout.phtml',
            'application/index/index' => __DIR__ . '/../view/application/index/index.phtml',
            'error/404'               => __DIR__ . '/../view/error/404.phtml',
            'error/index'             => __DIR__ . '/../view/error/index.phtml',
        ),

這應該處理4xx客戶端錯誤和5xx服務器錯誤。

對於特定模塊中的自定義錯誤頁面。

namespace ModuleName;

use Zend\ModuleManager\Feature\BootstrapListenerInterface;
use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
use Zend\ModuleManager\Feature\ConfigProviderInterface;
use Zend\Mvc\MvcEvent;

class Module implements
    BootstrapListenerInterface,
    AutoloaderProviderInterface,
    ConfigProviderInterface
{
    public function onBootstrap(MvcEvent $e)
    {
        $eventManager        = $e->getApplication()->getEventManager();
        $eventManager->attach('dispatch', array($this, 'loadConfiguration' ), 100);
    }

    public function loadConfiguration(MvcEvent $e)
    {
    $sm  = $e->getApplication()->getServiceManager();

        $controller = $e->getRouteMatch()->getParam('controller');
        if (0 !== strpos($controller, __NAMESPACE__, 0)) {
            //if not this module
            return;
        }

        //if this module
    $exceptionstrategy = $sm->get('ViewManager')->getExceptionStrategy();
    $exceptionstrategy->setExceptionTemplate('error/errorcustom');
    }

    public function getAutoloaderConfig(){ /* common code */ }
    public function getConfig(){ /* common code */}
}

該解決方案由http://samsonasik.wordpress.com/2012/09/19/zend-framework-2-create-custom-error-page/中的 “ samsonasik”提供

您可以附加一個偶數來處理觸發404時發生的情況:

Module.php

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $moduleRouteListener = new ModuleRouteListener();
    $moduleRouteListener->attach($eventManager);
    /**
     * Log any Uncaught Errors
     */
    $sharedManager = $e->getApplication()->getEventManager()->getSharedManager();
    $sm = $e->getApplication()->getServiceManager();
    $sharedManager->attach('Zend\Mvc\Application', 'dispatch.error',
         function($e) use ($sm) {
            /**
             * Decide what to do now we've got a problem...
             * Log the issue etc..
             * You could forward to some custom controller if you wanted..
             */
            //$sm->get('Zend\Log\Logger')->crit('an error occurred... bla');
            $controller = $e->getTarget();
            //$routeMatch = $e->getRouteMatch();
            $controller->layout('somelayout'); // possibly change the layout..
         }
    );
}
