How to use this token to validate the start of the session, AngularJS?

I am currently controlling the login with a WebService in laravel using the following library: JWTAuth

Here is the method in laravel:

public function userAuth(Request $request)
{

    $usuario        = $request->input('usuario');
    $password       = $request->input('password');
    $token          = null;

    try 
    {
        if (!$token = JWTAuth::attempt(['usuario' => $usuario, 'password' => $password])) 
        {
            $this->records  = Array();
            $this->message  = 'Datos incorrectos';
            $this->result   = false;
            $statusCode     = 200;

                $response = [
                    'message'   => $this->message,
                    'result'    => $this->result,
                    'records'   => $this->records,
                ];
            return response()->json($response, $statusCode);
        }
        else
        {
            $this->records = Auth::user();
            $this->message = 'Autenticado exitosamente';
            $this->result  = true;
            $statusCode    = 200;

                $response = [
                    'message'   => $this->message,
                    'result'    => $this->result,
                    'records'   => $this->records,
                ];
            return response()->json($response, $statusCode,compact('token'));
        }

    } 
    catch (JWTException $ex) 
    {
        return response()->json(['error' => 'somthing_went_wrong'], 500);    
    }
}

If the user and password parameters are correct, assign a token:

{"message": "Autenticado exitosamente","result": true,"records": {
"id": 1,
"usuario": "admin",
"nombre": "Administrador",
"email": "[email protected]",
"idtipousuario": 1,
"telefono": 54203090,
"estado": 1,
"created_at": "2017-02-13 18:34:01",
"updated_at": "2017-02-13 18:34:01"}}

The WebService tests it in postman and the token returns it correctly in the header (Headers)

With Angularjs in the app.state.js file I have the following code where I control the public and private views in such a way that in the browser if the person is not logged in with their token, they will not be able to access any view other than the login:

.run(['$state', '$rootScope', function($state, $rootScope){              
                    var token = 'token'; //Viene el Token
                    $rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
                    if (toState.module === 'private' && !token) {
                        console.log("Debe iniciar sesion");
                        $state.go('login');
                        e.preventDefault();
                    } else if (toState.module === 'public' && token) {
                        console.log("Contenido mostrado con credenciales correctas y token");
                        e.preventDefault();
                        $state.go('restricted.dashboard');
                    };
                });
            }
]);

The problem is that I do not know in what way I can use the token that comes in the WebService of the function run([]) and thus access the private routes if the token comes.
