php - 当Phalcon中不存在Controller时如何回退到IndexController？

Question

当我输入网址时:
http://localhost/asdfasdfasdcxccarf
Phalcon 给我这个信息:
PhalconException: AsdfasdfasdcxccarfController handler class cannot be loaded
这是合乎逻辑的，因为这个 Controller 不存在。

但是，如何让 Phalcon 将每个没有 Controller 的错误 url 重定向到我的默认 Controller IndexController？

您可以将以下调度程序服务添加到依赖注入(inject)容器。它将检查内部 Phalcon 错误(例如错误的 Controller )并将用户转发到指定的 Controller 和操作:

$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);
