ZendSkeleton 404 error - The requested URL could not be matched by routing

Question

So I've been following the fairly straightforward zend 2 skeleton example "album". I followed every step to the teeth and yet I cannot escape the 404 Error - requested URL could not be matched by routing whenever I input http://hostname/album for indexing, or http://hostname/album/add for adding, etc.

Naturally I looked into the routing found in the module.config.php file:

 <?php
 return array(
 'controllers' => array(
     'invokables' => array(
         'Album\Controller\Album' => 'Album\Controller\AlbumController',
     ),
 ),
 'router' => array(
     'routes' => array(
         'album' => array(
             'type'    => 'segment',
             'options' => array(
                 'route'    => '/album[/:action][/:id]',
                 'constraints' => array(
                     'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                     'id'     => '[0-9]+',
                 ),
                 'defaults' => array(
                     'controller' => 'Album\Controller\Album',
                     'action'     => 'index',
                 ),
             ),
         ),
     ),
 ),
 'view_manager' => array(
     'template_path_stack' => array(
         'album' => __DIR__ . '/../view',
     ),
 ),
);

Everything here looked fine, so I looked into the Module.php where the module.config.php is getting loaded from:

 <?php
  namespace Album;

  use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
  use Zend\ModuleManager\Feature\ConfigProviderInterface;

  class Module implements AutoloaderProviderInterface, ConfigProviderInterface
  {
      public function getAutoloaderConfig()
      {
         return array(
         'Zend\Loader\ClassMapAutoloader' => array(
             __DIR__ . '/autoload_classmap.php',
         ),
         'Zend\Loader\StandardAutoloader' => array(
             'namespaces' => array(
                 __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
             ),
         ),
     );
     }

     public function getConfig()
     {
          return include __DIR__ . '/config/module.config.php';
     }
  }

Again, everything looks fine here. Now I thought maybe the problem is that I didn't include the Album module in the application.config.php file (comments removed):

<?php
return array(

'modules' => array(
    'Application',
    'Album',
),

'module_listener_options' => array(

    'module_paths' => array(
        './module',
        './vendor',
    ),

    'config_glob_paths' => array(
        'config/autoload/{{,*.}global,{,*.}local}.php',
    ),

);

However it is included. I also have the AlbumController.php and the view (.phtml) files exactly where they should be. I double checked the paths multiple times yet the routes still do not work. Any ideas? Any suggestion would be appreciated.

PS - I am using a Ubuntu 14.04 Virtual Box.

EDIT

Here's the directory structure for the application: (I'm just listing the relevant files/folders to make it more readable)

• ZendSkel
  • public
    • index.php
  • config
    • application.config.php
  • module
    • Application
    • Album
      • Module.php
      • config
        • module.config.php
      • src
        • Album
          • Controller
            • AlbumController.php
          • Model
          • Form
      • view
        • album
          • album
            • index.phtml
            • add.phtml
            • edit.phtml
            • delete.phtml

Also, I am using virtual host with apache2.2.

Answer 1

For anyone, who is still looking for solution of this problem,

Clearing the data/cache folder, allowed routing to work as expected.

Answer 2

Like @Mayank Awasthi said:

Clearing the data/cache folder, allowed routing to work as expected.

This applies to Zend AND Laminas.

If the issue is not cache related, check your config and routing files!

Answer 3

If you follwoing the tutorial in the official page step by step and it shows 404. make sure 1- stop the serve, 2- enter "composer development-enable". 3- enter "composer serve" and then it should work. The tutorial does mention "composer development-enable" but it doesnt mention it in the right order, reason why a lot of people keep getting the 404
