To achieve that you would need to listen on the dispatch Event with high
priority that is being executed prior to any Contoller logic. Please try
this code in your Module.php.
namespace ModuleName;
use ModuleNama\Controller\MyController;
use Zend\EventManager\EventManagerInterface;
class Module
{
public function getControllerConfig()
{
return array(
'factories' => array(
'ModuleName\Controller\MyController' =>
function($sm) {
$events =
$sm->getServiceLocator()->get('EventManager');
$controller = new MyController();
$events->attach('dispatch', function
($e) use ($controller) {
$request = $e->getRequest();
$method =
$request->getMethod();
// your own initialization
logic here
if
($controller->params()->fromRoute('paramName', false)) {
return;
}
}, 100); // run before controller
action logic
$controller->setEventManager($events);
return $controller;
}
),
);
}
}
