Zend Framework 2 route not working correctly

Question

how can i add a default home page in routing?

my route works when i access this url {myapp}/modulename/controllername but when i access this {myapp}/modulename it returns a 404.

How can i fix that?

return array(
    'controllers'   => array(
        'invokables'    => array(
            'Modulename\Controller\Mycontroller'     => 'Modulename\Controller\TheController',
        ),
    ),

Answer 1

'Modulename\Controller\Mycontroller'     => 'Modulename\Controller\TheController',

Here you used the controller name is 'TheController'

   'defaults' => array(
                    '__NAMESPACE__' => 'Modulename\Controller',
                    'controller'    => 'My',
                    'action'        => 'index',
                ),

But here you specified controller name 'My'.

Change here 'controller' => 'The', and check

If your controller name is "UserController" then change

'Modulename\Controller\Mycontroller'     => 'Modulename\Controller\TheController',

 as

'Modulename\Controller\User'     => 'Modulename\Controller\UserController', 

 and 

'defaults' => array(
                    '__NAMESPACE__' => 'Modulename\Controller',
                    'controller'    => 'My',
                    'action'        => 'index',
                ),

  as

'defaults' => array(
                    '__NAMESPACE__' => 'Modulename\Controller',
                    'controller'    => 'User',
                    'action'        => 'index',
                ),

And change this(at after 'may_terminate')

'defaults' => array( 
                    '__NAMESPACE__' => 'Modulename\Controller',
                    'controller'    => 'User',
                    'action'        => 'index',
                    ),
                        ),

as

'defaults' => array(),

Answer 2

you dont have any controller named My in 'controller' => 'My',

you should change the controller invokable name :

'controllers'   => array(
    'invokables'    => array(
        'My'     => 'Modulename\Controller\TheController',
    ),
),

or change the default controller in routes definition to

'defaults' => array(
    '__NAMESPACE__' => 'Modulename\Controller',
    'controller'    => 'Modulename\Controller\Mycontroller',
    'action'        => 'index',
),

and this route definition is not correct either

'route'    => '[/:controller][/:action][/:id]',

it should be

'route'    => '[/:controller[/:action[/:id]]]',

Answer 3

thank you for your answers, i found an another way by putting some code in the module.php

Here's my code:

if($e->getRouteMatch()->getMatchedRouteName() == 'modulename') {
    $response->getHeaders()->addHeaderLine('Location', $e->getRequest()->getBaseUrl() . '/modulename/user/index');
    $response->setStatusCode(302);
}
