php - 如何在 Phalcon 中设置 404 页面

Question

如何在 Phalcon 中设置 404 页面以在 Controller / Action 不存在时显示？

Answer 1

您可以设置调度员为您执行此操作。

当您引导您的应用程序时，您可以这样做($di 是您的 DI 工厂):

use \Phalcon\Mvc\Dispatcher as PhDispatcher;

$di->set(
    'dispatcher',
    function() use ($di) {

        $evManager = $di->getShared('eventsManager');

        $evManager->attach(
            "dispatch:beforeException",
            function($event, $dispatcher, $exception)
            {
                switch ($exception->getCode()) {
                    case PhDispatcher::EXCEPTION_HANDLER_NOT_FOUND:
                    case PhDispatcher::EXCEPTION_ACTION_NOT_FOUND:
                        $dispatcher->forward(
                            array(
                                'controller' => 'error',
                                'action'     => 'show404',
                            )
                        );
                        return false;
                }
            }
        );
        $dispatcher = new PhDispatcher();
        $dispatcher->setEventsManager($evManager);
        return $dispatcher;
    },
    true
);

创建一个ErrorController

<?php

/**
 * ErrorController 
 */
class ErrorController extends \Phalcon\Mvc\Controller
{
    public function show404Action()
    {
        $this->response->setStatusCode(404, 'Not Found');
        $this->view->pick('404/404');
    }
}

和一个 404 View (/views/404/404.volt)

<div align="center" id="fourohfour">
    <div class="sub-content">
        <strong>ERROR 404</strong>
        <br />
        <br />

    </div>
</div>
