Laravel 5.1 Socialite默认登录路由

我尝试将默认登录路径设置为简单的/auth，并定义如下

namespace App'Http'Controllers;
use Socialite;
use Illuminate'Routing'Controller;
class AuthController extends Controller
{
    protected $loginPath = '/auth';
    protected $redirectPath = '/dashboard';
    /**
     * Redirect the user to the GitHub authentication page.
     *
     * @return Response
     */
    public function redirectToProvider()
    {
        return Socialite::driver('github')->redirect();
    }
    /**
     * Obtain the user information from GitHub.
     *
     * @return Response
     */
    public function handleProviderCallback()
    {
        $user = Socialite::driver('github')->user();
        // $user->token;
    }
}

调用回调后我也没有返回任何东西，因为我认为我已经如上所述定义了它。我错过了什么?现在，如果我想直接访问页面仪表板在浏览器上输入URL, Laravel将带我到/auth/login页
