Zend Framework 2路由段错误

Question

I tried to understand ZF2 Module Routing, but I have a problem. I would like to list products by period and generate a link for each of the periods (today, this-week, this-month, all). For example:

<a href="<?php echo $this->url('Application', array('action' => 'index', 'period' => 'this-week')); ?>">This week</a>

output: localhost/application/this-week/

When I click on this link, appears this error:

A 404 error occurred
Page not found.
The requested controller was unable to dispatch the request.

this is my module.config:

 .....................
       'router' => array(
             'routes' => array(
                 'Application' => array(
                     'type'    => 'Segment',
                     'options' => array(
                         'route'    => '/application/[:action/][:period/]',
                         'constraints' => array(
                             'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                             'period' => '(today|this-week|this-month|all)'
                         ),
                         'defaults' => array(
                             'controller' => 'Application\Controller\ApplicationController',
                             'action' => 'index',
                             'period' => 'all'
                         ),
                     ),
                 ),
             ),
         ), ...........................

Where am I doing wrong? I tried to change:

 'period' => '(today|this-week|this-month|all)'

to

'period' => '[a-zA-Z][a-zA-Z0-9_-]*'

but it doesn't work again.

inside my controller, index action is empty actually:

public function indexAction(){

}

index.phtml contains only a echo link:

<a href="<?php echo $this->url('Application', array('action' => 'index', 'period' => 'this-week')); ?>">This week</a>

NEW EDIT

I've decided to using query string for my use. It's more simple to implement, it isn't elegant but is moooore simple :D ...I thought like so, with a switch for "higher rigidity":

public function indexAction(){
   ...getQuery method ...

   switch($period){
       case'today':
       .......
       break;
        case'this-week':
       .......
       break;
        case'this-month':
       .......
       break;
       default:
       // if query string is null or contains other characters, sets default   case "all"
       ... 
       break;
   } 
}

url function:

<a href="<?php echo $this->url('Application', array('action' => 'index'), array('query' => array('period' => 'this-week'); ?>">This week</a>

output:

localhost/adopted/?period=this-week

inside module.config:

   .....................
           'router' => array(
                 'routes' => array(
                     'Application' => array(
                         'type'    => 'Segment',
                         'options' => array(
                             'route'    => '/application/[:action/]',
                             'constraints' => array(
                                 'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                             ),
                             'defaults' => array(
                                 'controller' => 'Application\Controller\ApplicationController',
                                 'action' => 'index',
                             ),
                         ),
                     ),
                 ),
             ), ...........................

Answer 1

With a path like /application/this-week/, ZF has no way of knowing whether this-week is an action or period, since both are optional and the string matches the constraints for both. To fix this you need to remove this ambiguity. You have a few options:

Option 1: Add some constraints for action, so that it will only match valid actions, something like:

'constraints' => array(
    'action' => '(index|foo|bar)',
    'period' => '(today|this-week|this-month|all)'
),

Option 2: Make either action or period required, by removing the square brackets from them in your routing config. (If you make index required you will end up with 'index' in your URLs.)

Option 3: Add a separate route for this URL which doesn't include the action in the path (since you don't want it there), but has some other way of distinguishing it from the application route:

'router' => array(
     'routes' => array(
         'Application' => array(
             'type'    => 'Segment',
             'options' => array(
                 'route'    => '/application/[:action/]',
                 'constraints' => array(
                     'action' => '[a-zA-Z][a-zA-Z0-9_-]*''
                 ),
                 'defaults' => array(
                     'controller' => 'Application\Controller\ApplicationController',
                     'action' => 'index'
                 ),
             ),
         ),
         'period' => array(
             'type'    => 'Segment',
             'options' => array(
                 'route'    => '/application/period/[:period/]',
                 'constraints' => array(
                     'period' => '(today|this-week|this-month|all)'
                 ),
                 'defaults' => array(
                     'controller' => 'Application\Controller\ApplicationController',
                     'action' => 'index',
                     'period' => 'all'
                 ),
             ),
         ),
     ),
 ), 

You'd also change the URL helper call:

<a href="<?php echo $this->url('period', array('period' => 'this-week')); ?>">This week</a>

This would give you a URL like /application/period/this-week/.
