You can use the API of the 'router' service (an instance of Zend\Mvc\Router\Http\TreeRouteStack) and add a route dynamically.
How you attach the route to the route stack is up to you, you could extend the default router factory Zend\Mvc\Service\RouterFactory with your own routes from config.
use MyModule\Mvc\Service;
use Zend\Mvc\Service\RouterFactory;
use Zend\ServiceManager\ServiceLocatorInterface;
class MyRouterFactory extends RouterFactory
{
public function createService(ServiceLocatorInterface $serviceLocator, $cName = null, $rName = null)
{
$serviceManager = $serviceLocator->getServiceLocator();
$router = parent::createService($serviceLocator, $cName, $rName);
$config = $serviceManager->get('config');
$router->addRoute('advertise', [
'type' => 'hostname',
'options' => [
'route' => $config['some_other_config_key'],
'defaults' => [
'controller' => 'Advertise\Controller\Advertise',
'action' => 'index'
]
],
'priority' => 123
]);
return $router;
}
}
Remember to register it with the name Router in module.config.php to replace the default implementation.
'service_manager' => [
'factories' => [
'Router' => 'MyModule\Mvc\Service\MyCustomRouterFactory',
],
],
The nice thing with this approach is that the routers construction is all kept in one place; also as you are adding it with a factory class
you have access to other services should you need them.
Alternatively, you could add it via an event, although being triggered via the event manager, this method would likely be more resource intensive.
namespace MyModule;
use Zend\ModuleManager\InitProviderInterface;
use Zend\ModuleManager\ModuleManagerInterface;
use Zend\Mvc\Application;
use Zend\Mvc\MvcEvent;
class Module implements InitProviderInterface
{
// init is called when the module is initilised, we can use this to add a listener to the
// 'bootstrap' event
public function init(ModuleManagerInterface $manager)
{
$eventManager = $manager->getEventManager()->getSharedManager();
$eventManager->attach(Application::class, MvcEvent::EVENT_BOOTSTRAP, [$this, 'addRoutes']);
}
public function addRoutes(MvcEvent $event)
{
$serviceManager = $event->getApplication()->getServiceManager();
$router = $serviceManager->get('Router');
$config = $serviceManager->get('Config');
$router->addRoute('advertise', [
'type' => 'hostname',
'options' => [
'route' => $config['some_other_config_key'],
'defaults' => [
'controller' => 'Advertise\Controller\Advertise',
'action' => 'index'
]
],
'priority' => 123
]);
}
}
