Symfony第一步问题

Question

I'm newbie in Symfony and I'm following a tutorial. The first excercise is very simple, but I don't know why is not working.

In my source folder I first tried with these lines:

<?php

namespace AppBundle\Controller;


use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;

class GenusController
{
    /**
     * @Route("/genus")
     */

    public function showAction()
    {
        return new Response('Test ');

    }

}

I tried in in my browser:

http://localhost:8888/my_project/web/genus

And it works. But then if I add new lines:

class GenusController
{
    /**
     * @Route("/genus/{genusName}")
     */

    public function showAction($genusName)
    {
        return new Response('The genus: '.$genusName);

    }

}

and tested it:

http://localhost:8888/my_project/web/genus/test

My browser displays:

Oops! An Error Occurred The server returned a "404 Not Found". Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

What is missing? Any suggestions?

Thank you in advance

Answer 1

In prod environment: the configuration information is cached and not automatically refreshed. It means:

• @nnotation in php files are cached
• .yml file are cached
• .xml file are cached
• *.twig file are cached

The error you are having is the new route you've created is not cached and not accessible to prod environment.

It means you either have to call app/console cache:clear --env=prod everytime or you have to use the dev environnement which is far better when developping. It provides better error message for 404 and 500 errors too.

It means you have to use the app_dev.php instead of app.php . You can try

http://localhost:8888/app_dev.php/my_project/web/genus/test
