laravel 5.3自定义登陆成功后的跳转路由无效？

下面是我LoginController中的代码：

<?php

namespace App\Http\Controllers\User\Ui\Auth;

use App\Http\Controllers\Controller as Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Support\Facades\Redirect;

class LoginController extends Controller
{
/
|--------------------------------------------------------------------------
| Login Controller
|--------------------------------------------------------------------------
|
| This controller handles authenticating users for the application and
| redirecting them to your home screen. The controller uses a trait
| to conveniently provide its functionality to your applications.
|
/

use AuthenticatesUsers;

/**
 * Where to redirect users after login.
 *
 * @var string
 */

// protected $redirectTo = '/';

/**
 * Create a new controller instance.
 *
 * @return void
 */
public function __construct()
{
    $this->middleware('guest', ['except' => 'logout']);
    config(['app.name' => '点跃']);
}

public function index()
{
    return \Auth::user();
}

protected function redirectTo()
{
    die('ok');
    return Redirect::route('index');
}

}

但是登录成功后任然跳转到/home那个页面
