当Phalcon中不存在Controller时,如何回退到IndexController？

Question

当我输入url时:

http://localhost/asdfasdfasdcxccarf

Phalcon给了我这样的信息:

PhalconException: AsdfasdfasdcxccarfController handler class cannot be loaded

这是合乎逻辑的,因为这个控制器不存在.

但是,如何让Phalcon将每个没有控制器的坏URL重定向到我的默认控制器IndexController？

您可以将以下调度程序服务添加到依赖项注入容器.它将检查内部Phalcon错误(例如错误的控制器)并将用户转发到指定的控制器和操作:

$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);
