LoginController.php

<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class LoginController extends Controller
{
    use AuthenticatesUsers;
    protected $username = 'username';
    protected $redirectTo = '/dashboard';
    protected $guard = 'web';
    public function getLogin()
    {
        if (Auth::guard('web')->check())
        {
            return redirect()->route('dashboard');
        }
        return view('login');
    }
    public function postLogin(Request $request)
    {
        $auth = Auth::guard('web')->attempt(['username' => $request->username, 'password' => $request->password, 'active' => 1]);
        if ($auth)
        {
            return redirect()->route('dashboard');
        }
        return redirect()->route('/');
    }
    public function getLogout()
    {
        Auth::guard('web')->logout();
        return redirect()->route('/');
    }
}

フォームを送信するときの次のルートは正常に機能しています。

Route::get('/', ['as' => '/', 'uses' => 'LoginController@getLogin']);
Route::get('/login', ['as' => 'login', 'uses' => 'LoginController@getLogin']);

Route::group(['middleware' => ['autheticates', 'roles']], function (){
    Route::get('/logout', ['as' => 'logout', 'uses' => 'LoginController@getLogout']);
    Route::get('/dashboard', ['as' => 'dashboard', 'uses' => 'DashboardController@dashboard']);
});

Middleware/Autheticates.php

class Autheticates
{
    public function handle($request, Closure $next, $guard = 'web')
    {
        if (!Auth::guard($guard)->check())
        {
            return redirect()->route('/');
        }
        return $next($request);
    }
}

ミドルウェア/Roles.php

class Roles
{
    public function handle($request, Closure $next)
    {
        $roles = $this->getRequiredRoleForRoute($request->route());
        if ($request->user()->hasRole($roles) || $roles){
            return $next($request);
        }
        return redirect()->route('noPermissions');
    }
    private function getRequiredRoleForRoute($route)
    {
        $actions = $route->getAction();
        return isset($actions['roles']) ? $actions['roles'] : null;
    }
}

Answer 1

定義したルートのエラー。そのgetはpostに変更する必要があります

これを変える

Route::get('/login', ['as' => 'login', 'uses' => 'LoginController@getLogin']);

これに

Route::post('/login', ['as' => 'login', 'uses' => 'LoginController@getLogin']);

---

action="{{ route('login') }}" # form Submit action

Answer 2

ルートの答えは

Route::post('/login', ['as' => 'login', 'uses' => 'LoginController@getLogin']);
