Phalcon：找不到頁面錯誤處理程序

Question

如何在此應用程序中創建404錯誤頁面以進行手動引導？ http://album-o-rama.phalconphp.com/

我使用這個調度程序：

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

）;

Answer 1

在index.php中嘗試一下：

$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);

Answer 2

這里推薦的功能是：

http://docs.phalconphp.com/zh_CN/latest/reference/routing.html#not-found-paths

有可能

routing.html＃dealing-with-extra-trailing-斜杠

對於手動引導，可以使用路由器來代替使用調度程序

/**
 * Registering a router
 */
$di->set('router', require __DIR__.'/../common/config/routes.php');

然后在“ common / config / routes.php”中添加此路由規則。

$router->notFound(array(
    'module' => 'frontend',
    'namespace' => 'AlbumOrama\Frontend\Controllers\\',
    'controller' => 'index',
    'action' => 'route404'
));

最后定義一個控制器和一個視圖以捕獲此操作。

瞧！404錯誤頁面！

僅作評論，我要求為您提到的應用請求此解決方案：

Answer 3

對於新版本的Phalcon您可以通過將此代碼添加到service.php來使用路由來處理錯誤service.php

$di->set('router',function() use($Config){
    $router = new \Phalcon\Mvc\Router();
    $router->notFound(array(
        "controller" => "error",
        "action" => "error404"
    ));
    return $router;
}); 

Answer 4

public function show404Action()
{
    $this->response->setStatusCode(404, 'Not Found');
    $this->view->pick('error/show404');
}
