访客：多声道管理员重定向到用户登录表单，而不是laravel 5.4

Question

我正在尝试在我的网站上进行管理员登录。我到目前为止遵循了教程，但问题是何时使用中间件guest：admin就像这样

public function __construct()
{
    $this->middleware('guest:admin', ['except' => 'logout']);
}

然后输入 localhost / website / admin ，然后打开 localhost / website / login

页面

如果我从guest：admin中删除管理员，那么它不会登录并将我重定向到 localhost / website / login ，而不是转到管理员登录页面。

我已经覆盖了showLoginForm（）函数和保护功能。我的LoginController看起来像这样。

    <?php

namespace App\Http\Controllers\Admin;

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

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 = '/admin/pages/addstudent';

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

    /**
     * Show the application's login form.
     *
     * @return \Illuminate\Http\Response
     */
    public function showLoginForm()
    {
        return view('admin.index');
    }

    /**
     * Get the guard to be used during authentication.
     *
     * @return \Illuminate\Contracts\Auth\StatefulGuard
     */
    protected function guard()
    {
        return Auth::guard('admin');
    }
}

我做了太多脑力激荡。请帮忙！！。非常感谢。
