php - ReflectionException - 中间件类不存在 Laravel 5.5

Question

我知道我不是第一个遇到这样问题的人。我已经阅读了关于 Stackoverflow 和其他来源的所有现有信息，但它无法解决我的问题，我总是会得到一个 ReflectionException Class App\Http\Middleware\xxx does not exist。

<?php

namespace App\Http\Middleware\xxx;

use Closure;

class xxx
{

    public function handle($request, Closure $next)
    {

        return $next($request);
    }
}

不是开玩笑，这真的是我的课。我已将其重命名为 xxx 以避免打字错误。

我所有的路由都会通过 web 和 admin 中间件:

Route::middleware(['web', 'admin'])->group(function() {  

这是我的/app/Http/Kernel.php:

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        \App\Http\Middleware\xxx::class,
    ],  

• 文件名为xxx.php，位置为App\Http\Middleware\。
• 命名空间正确
• composer dump-autoload 不能解决问题

我还尝试修改我的 composer.json:

"autoload": {
    "classmap": [
        "database/seeds",
        "database/factories",
        "App/Http/Middleware/xxx.php"
    ],

导致以下警告:

Warning: Ambiguous class resolution, "App\Http\Middleware\xxx\xxx" was found in both "$baseDir . '/app/Http/Middleware/xxx.php" and "/code/App/Http/Middleware/xxx.php", the first will be used.

Answer 1

首先，将命名空间更改为:

namespace App\Http\Middleware;

然后从 composer.json 中删除 "App/Http/Middleware/xxx.php" 并运行 composer du

你也需要remove web middleware from the routes file如果您使用的是 5.2.27 及更高版本:

Route::middleware(['admin'])->group(function() {
