Laravel: How to use session in the whole app?

I want use session in Laravel like $_SESSION['test'] in a normal PHP. I tried this in Laravel,but the data will be not stored when i use the session in another Controller

// User CONTROLLER

class UserController extends Controller
{
    public function testSession(Request  $request)
    {
       // ...
    Session::set( 'id','1' );
    $request->session()->put('username', 'simo');

    }
}

Another CONTROLLER

class AnotherController extends Controller
{
    public function GetMySession(Request  $request)
    {
       // ...
    dd($request->session()->all());// 

    }
}

Now username and id are not stored in the Session why ??
