迁移 laravel 5 和 get 类不存在

我在app/Http/Middleware/上创建了一个名为CorsMiddleware.php的中间件。这很简单，它已经在我的离线宅基地盒上运行。问题发生在我的远程计算机上：

ReflectionException in Container.php line 738:
Class App'Http'MiddleWare'CorsMiddleware does not exist

我的文件结构：

Middleware:
total 20
-rwxr-xr-x 1 CasatoroWeb CasatoroWeb  676 Mar 16 12:53 Authenticate.php
-rwxr-xr-x 1 CasatoroWeb CasatoroWeb 1570 Mar 16 12:53 CorsMiddleware.php
-rwxr-xr-x 1 CasatoroWeb CasatoroWeb  300 Mar 16 12:53 EncryptCookies.php

-rwxr-xr-x 1 CasatoroWeb CasatoroWeb  311 Mar 16 12:53 VerifyCsrfToken.php

我的班级：

<?php namespace App'Http'Middleware;
use Closure;
class CorsMiddleware {
    /**
     * Run the request filter.
     *
     * @param  'Illuminate'Http'Request  $request
     * @param  'Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        /*
         * Get the response like normal.
         * When laravel cannot find the exact route it will try to find the same route for different methods
         * If the method is OPTION and there are other methods for the uri,
         * it will then return a 200 response with an Allow header
         *
         * Else it will throw an exception in which case the user is trying to do something it should not do.
         */
        $response = $next($request);
        // We only want the headers set for the api requests
        if ($request->segment(1) == 'api') {
            // Set the default headers for cors If you only want this for OPTION method put this in the if below
            $response->headers->set('Access-Control-Allow-Origin','*');
            $response->headers->set('Access-Control-Allow-Headers','Content-Type, X-Auth-Token, Origin, Authorization');
            // Set the allowed methods for the specific uri if the request method is OPTION
            if ($request->isMethod('options')) {
                $response->headers->set(
                    'Access-Control-Allow-Methods',
                    $response->headers->get('Allow')
                );
            }
        }
        return $response;        
    }
}

我的内核.php

protected $middleware = [
    'Illuminate'Foundation'Http'Middleware'CheckForMaintenanceMode::class,
    'App'Http'MiddleWare'CorsMiddleware::class,
];

我尝试通过此处发布的解决方案来解决它 - https://laracasts.com/discuss/channels/general-discussion/l5-cant-get-custom-middleware-to-work-on-routes：

composer dump-autoload
php artisan clear-compiled
php artisan optimize

并且还通过运行

php artisan cache:clear

我不知道还能去哪里找。谁能指出我正确的方向？
