Yii framework Urlpaths

I am trying to pass an argument(station code) to an module controller action.

Path: index.php?r=rcont/rcont/station/cod

it is redirecting to site error page(page not found)

when I try the path index.php?r=rcont/rcont/station/

It errors saying

Bad Request "Missing parameter code"

main.php





	'urlManager'=> [

	     'class' => 'yii\web\UrlManager',

	     'enableStrictParsing' => true,	

            'rules'=> [

				[

					'class' => 'yii\rest\UrlRule',

					'controller' => [ 'rcont/rcont'], 

					'only' => ['station'],

                                        //I dont know next

				]

               //'rcont/rcont/station/<code>' => 'rcont/rcont/station/' not even this worked to me

            ],

        ],



main-config.php





         'modules' => [


		'rcont' => [

			'class' => 'app\modules\rcont\Module',

		],	

	



Controller





class RcontController extends \yii\web\Controller 

{

 public function actionStation($code)

    {

		echo $code;


    }

}
