如何在phalcon框架中应用路由器/ roite？

Here, in docs, is written about how to create routes: http://docs.phalconphp.com/en/latest/reference/routing.html

But i can't find how i can inject them in application. What i need to do, to make my application use defined routes?

Should i inject router (or how?)

The router can be registered in the DI (in your public/index.php) this way:

$di->set('router', function() {

    $router = new \Phalcon\Mvc\Router();

    $router->add("/login", array(       
        'controller' => 'login',
        'action' => 'index',
    ));

    $router->add("/products/:action", array(        
        'controller' => 'products',
        'action' => 1,
    ));

    return $router;
});

Also is possible to move the registration of routes to a separate file in your application (i.e app/config/routes.php) this way:

$di->set('router', function(){
    require __DIR__.'/../app/config/routes.php';
    return $router;
});

Then in the app/config/routes.php file:

<?php

$router = new \Phalcon\Mvc\Router();

$router->add("/login", array(       
    'controller' => 'login',
    'action' => 'index',
));

$router->add("/products/:action", array(        
    'controller' => 'products',
    'action' => 1,
));

return $router;
