Laravel 中间件

Question

我用这段代码创建了一个 Laravel 中间件：

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
use App\Containers\Modals\Models\Modal;

class ModalsMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next, string $modalNames): Response
    {
        $modals = explode(',', $modalNames);
        foreach ($modals as $modalName) {
            $modal = Modal::where('slug', $modalName)->first();
            if (!$modal->enabled) {
                abort(404);
            }
        }
        return $next($request);
    }
}

然后我更新了

Kernel.php

:

**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array<string, class-string|string>
     */
    protected $routeMiddleware = [
       ...,
       'modals' => \App\Http\Middleware\ModalsMiddleware::class,
    ];

对于我的路线组，我添加了以下内容：

Route::group([
    'prefix' => 'api/v1/routeName',
    'middleware' => ['auth:api', 'modals:AModalName']
], function() {...});

然后我跑了：

php artisan optimize && php artisan config:cache && php artisan cache:clear && php artisan config:clear && composer dump-autoload

然后停止服务然后我重新运行应用程序

但是我遇到了这个错误：

"message": "Target class [modals] does not exist.",
    "exception": "Illuminate\\Contracts\\Container\\BindingResolutionException",

我该如何解决这个问题？

在 Larave 11 中，您必须在

bootstrap/app.php

文件中注册中间件。

->withMiddleware(function (Middleware $middleware) {
        $middleware->alias([
            'modals' => \App\Http\Middleware\ModalsMiddleware::class,
        ]);
    })
