Symfony2：找不到路由/ demo / contactus

Question

I am new to symfony and following the AcmeDemo i created a new page for Contact Us. At the moment it is working for the url localhost:8000/contactus but following the same implementation of demo/secured/login it should be localhost:8000/demo/contactus which gives 404.

I am not sure what wrong i am doing.

routing.yml

_demo_contactus:
 resource: "@AcmeDemoBundle/Controller/ContactusController.php"
 type:  annotation

ContactusController

<?php 

namespace Acme\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;


class ContactusController extends Controller
{
/** 
* @Route("/contactus", name="_demo_contactus")
* @Template()
**/
    public function indexAction()
    {
        return array();
    }
}

?>

And then i have my view which is i am sure correct. Please provide the detailed answer so that it can help me in clearing my concepts as well. Thanks !!!

Answer 1

If you take a look at the SecuredController from the AcmeDemoBundle, you'll see that the class declaration has this annotation at the start:

/**
 * @Route("/demo/secured")
 */
class SecuredController extends Controller
{
    // ...

This annotation prefixes all subsequent routes in the Controller class with /demo/secured. Therefore, you should write your own Controller using the same fashion:

/** 
 * @Route("/demo")
 */
class ContactusController extends Controller
{
    // ...

See the docs concerning Route Prefixing for more information

alternatively, you could also leave the ContactusController class alone and modify your route import instead:

_demo_contactus:
    resource: "@AcmeDemoBundle/Controller/ContactusController.php"
    type:  annotation
    prefix: /demo

You're also using the same route name twice, which means Symfony will reload routes and overwrite anything you had before for _demo_contactus. Try the following:

routing.yml

_demo_contactus:
    resource: "@AcmeDemoBundle/Controller/ContactusController.php"
    type:  annotation

ContactusController

<?php 

namespace Acme\DemoBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

/** 
 * @Route("/demo/contactus")
 */
class ContactusController extends Controller
{
    /** 
    * @Route("/", name="_demo_contactus_home")
    * @Template()
    **/
    public function indexAction()
    {
        return array();
    }
}

Make sure you try both /demo/contactus and /demo/contactus/.. it may be looking at that slash
