unable to get route name from url in zend framework 2 - zend-framework2

Question

I'm using Zend Framework 2, this is my code:
$prevsingletrackurl = $this->getRequest()->getHeader('Referer')->getUri();
From this code which is defined in a controller's method I'm getting previous URL, now what I need to know some information of this from this, it contains which route, controller, method for my own requirement.

Answer 1

You can use the route stack itself to try to match it. It will return you a RouteMatch if the request object matched:
use Zend\Mvc\Router\RouteMatch;
$referer = $this->getRequest()->getHeader('Referer')->getUri();
$request = clone $this->getRequest();
$request->setUri($referer);
$match = $routeStack->match($request);
if ($match instanceof RouteMatch) {
$route = $match->getMatchedRouteName();
}
You can access the route stack ("router") from the service locator; in the root service locator, it is registered as 'Router'. You can inject the route stack in your factory. For instance in a Controller:
use MyModule\Controller\MyController;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
class MyControllerFactory implements FactoryInterface
{
public function createService(ServiceLocatorInterface $sl)
{
$router = $sl->getServiceLocator()->get('Router');
$controller = new MyController($router);
return $controller;
}
}
Use it in your controller as this:
use Zend\Mvc\Controller\AbstractActionController;
use Zend\Mvc\Router\Http\TreeRouteStack;
class MyController extends AbstractActionController
{
protected $router;
public function __construct(TreeRouteStack $router)
{
$this->router = $router;
}
protected function getRouter()
{
return $this->router;
}
}

This code i have used inside a controller action method
$request = $this->getRequest();
$getHeaderReferer=$request->getHeader('Referer');
if (!empty($getHeaderReferer))
{
$prevsingletrackurl = $getHeaderReferer->getUri(); // get previous url
//echo "<br>previous usrl=>".$prevsingletrackurl;
$controller = $this->getEvent()->getRouteMatch()->getParam('controller'); // get controller name
//**** code to get previous url route , controller name , action/method name starts
$request->setUri($prevsingletrackurl);
$router =$this->getServiceLocator()->get('Router');// this gives instance of /Zend/Mv/Router/Http/TreeRouteStack
//echo "<br>router=>".$router->toString();
$routeMatch = $router->match($request); // this gives instance of /Zend/Mv/Router/Http/RouteMatch
$routename="";
if( $routeMatch instanceof RouteMatch )
{
$urlwholeroutedataAr=$routeMatch->getParams();
if(!empty($urlwholeroutedataAr))
{
$controllerdata=$urlwholeroutedataAr['controller'];
$actionmethod=$urlwholeroutedataAr['action'];
if(array_key_exists('trackdata',$urlwholeroutedataAr))
{
$trackdata=$urlwholeroutedataAr['trackdata'];
}
$controllerdataAr=explode("\\",$controllerdata);
if(count($controllerdataAr)>0)
{
$controllername=end($controllerdataAr);
}
}
$routename=$routeMatch->getMatchedRouteName();
}
}
