Yii Framework - from url to route - yii

Question

I searched, but couldnt find something.
So, I have route rules:
...
'/reg' => '/user/user/registration',
...
in
Yii::app()->request
I couldn find any route information.
So, how can I get in module init function and having only url, route lile
/reg -> user/user/registration
UPD

Answer 1

The route is only available from the running controller. By the time when a module is initialized the controller is not yet available, thus you can't find out the route there. (You can follow CWebApplication::processRequest to see what happens when a request is resolved up to the point where the controller is run.)
It depends on what you try to achieve, but you could override WebModule::beforeControllerAction to do something before the module controller is run.

Answer 2

Today (next day after my question), I could solve this.
I will try to explain:
As Michael wrote, we cant know in module in which controller we are.
But I net get just reversed route, so, its quite esay.
Yii::app()->getUrlManager()->parseUrl('/reg');
This will return my reversed route
user/user/registration
parseUrl

Solution for Yii 1.1.15 workes for me.
class HttpRequest extends CHttpRequest {
protected $_requestUri;
protected $_pathInfo;
public function setUri($uri){
$this->_requestUri = $uri;
}
public function setPathInfo($route){
$this->_pathInfo = $route;
}
public function getPathInfo(){
/* copy from parent */
}
public function getRequestUri(){
/* copy from parent */
}
}
The usage:
$uri_path = 'my/project-alias/wall';
/** #var HttpRequest $request */
$request = clone Yii::app()->getRequest();
$request->setUri($uri_path);
$request->setPathInfo(null);
$route = Yii::app()->getUrlManager()->parseUrl($request);
//$route equals 'project/profile/wall' etc here (like in route rules);

I'm using a slightly different sub-class of CHttpRequest:
class CustomHttpRequest extends \CHttpRequest
{
/**
* #var string
*/
var $pathInfo;
/**
* #var string
*/
private $method;
public function __construct($pathInfo, $method)
{
$this->pathInfo = $pathInfo;
$this->method = $method;
}
public function getPathInfo()
{
return $this->pathInfo; // Return our path info rather than the default
}
public function getRequestType()
{
return $this->method;
}
}
Then to call it (to create a controller, which is what I want):
$request = new CustomHttpRequest($uri, $method); // e.g. 'my/project-alias/wall' and 'GET'
$route = \Yii::app()->getUrlManager()->parseUrl($request);
list($jcontroller, $actionName) = \Yii::app()->createController($route);
