Laravel - 从自定义类重定向

Question

How can I redirect application to specific url from my custom class?

Let's say I have my custom class API in Laravel Application:

class API {

    private function generic_request( $uri ) 
    {
       $response = $this->getResponse($uri);
       if($response == 'bad_token') 
       {
          //redirect to login screen with message
       }
    }

In my controller function:

public function add_employee() {
    $data['employee_positions'] = API::generic_request('/employees/position_list');
    $this->layout->content = View::make('employees.add_employee')->with($data);
}

I've tried Events, but you can't redirect from Event listener. Right now I'm using Exceptions but I feel like it's wrong approach. For example:

App::abort(401);

and then in global.php :

App::error(function(Exception $exception, $code)
{
    /*CORE API Exceptions*/

    if($code == 401) 
    {
        Session::put('message','System Action: Expired Token');
        return Redirect::to('login');
    }
}

You just have to create a response and return it all the way back to Laravel:

<?php

class API {

    public function doWhatever($uri)
    {
        return $this->generic_request($uri);
    }

    private function generic_request( $uri ) 
    {
       $response = $this->getResponse($uri);

       if($response == 'bad_token') 
       {
          return Redirect::to('login')->with('message', 'your message');
       }

    }

}

Route::get('test', function()
{
    return with(new API)->doWhatever('yourURI');
});
