Phalcon ispatcher has detected a cyclic routing - php

Question

I create a new project with Phalcon framework.
For begin, my environment is :
Phalcon 3.2.12
Windows 10
Xampp / PHP 7.2
At this time, I have created one login page in the index. When I launch my application, I have this message :
Fatal error: Uncaught Phalcon\Mvc\Dispatcher\Exception: Dispatcher has
detected a cyclic routing causing stability problems in
\public\index.php:32
Line 32 :
echo $application->handle()->getContent();
There is my dispatcher in services.php :
$di->setShared('dispatcher', function () use ($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' => 'index',
'action' => 'show404'
));
return false;
}
});
$dispatcher = new PhDispatcher();
$dispatcher->setEventsManager($evManager);
return $dispatcher;
});
There is my IndexController :
class IndexController extends ControllerBase
{
public function indexAction()
{
$this->view->setLayout('login');
}
public function show404Action()
{
$this->view->setLayout('login');
$this->response->setStatusCode(404, "Not Found");
$this->view->pick('index/404');
}
}
There is my ControllerBase :
public function beforeExecuteRoute($dispatcher)
{
$isValid = true;
// check auth
if ($dispatcher->getControllerName() !== 'index') {
$isValid = false;
$this->view->disable();
$this->response->setStatusCode(401, 'Vous devez vous identifier pour accéder à votre environnement.');
if (!$this->request->isAjax()) {
$this->response->redirect('index');
}
}
return $isValid;
}
index.php
define('APP_PATH', realpath('..'));
/**
* Define APPLICATION_ENV (DEV,STAGING,PREPROD,PROD)
*
* #var APPLICATION_ENV string
*/
defined('APPLICATION_ENV') || define('APPLICATION_ENV', (isset($_SERVER['APPLICATION_ENV']) ? $_SERVER['APPLICATION_ENV'] : 'PROD'));
/**
* Read the configuration
*/
$config = include APP_PATH . "/app/config/" . strtolower(APPLICATION_ENV) . ".config.php";
/**
* Read auto-loader
*/
include APP_PATH . "/app/config/loader.php";
/**
* Read services
*/
include APP_PATH . "/app/config/services.php";
/**
* Handle the request
*/
$application = new \Phalcon\Mvc\Application($di);
echo $application->handle()->getContent();
If I put a var_dump at the begin of method beforeExecuteRoute, I don't see the result of var_dump.
Have you an idea?
Thanks

Answer 1

probably you forward to something that can't be found. Try to rename show404 to showNotFound, you can inspect the $dispatcher->getControllerName() and getActionName() during the afterExecuteRoute event to see why your handler or action can never be found
public function showNotFoundAction()
{
$this->view->setLayout('login');
$this->response->setStatusCode(404, "Not Found");
$this->view->pick('index/404');
}
And
$dispatcher->forward(array(
'controller' => 'index',
'action' => 'showNotFound'
));
