您可以將以下調度程序服務添加到依賴項注入容器。它會檢查內部爾康錯誤(如錯誤的控制器爲例)並轉發用戶到指定的控制器和動作:
$di->set('dispatcher', function() {
$eventsManager = new \Phalcon\Events\Manager();
$eventsManager->attach("dispatch:beforeException", function($event, $dispatcher, $exception) {
//Handle 404 exceptions
if ($exception instanceof \Phalcon\Mvc\Dispatcher\Exception) {
$dispatcher->forward(array(
'controller' => 'index',
'action' => 'show404'
));
return false;
}
//Handle other exceptions
$dispatcher->forward(array(
'controller' => 'index',
'action' => 'show503'
));
return false;
});
$dispatcher = new \Phalcon\Mvc\Dispatcher();
//Bind the EventsManager to the dispatcher
$dispatcher->setEventsManager($eventsManager);
return $dispatcher;
}, true);
