ReflectionException - Laravel 5.5 中不存在中间件类

Question

我知道我不是第一个遇到这种问题的人。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);
    }
}

不开玩笑，这真的是我的课。我已将其重命名xxx以避免输入错误。

我的所有路由信息都会通过该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,
    ],  

• 文件已命名xxx.php，位置为App\Http\Middleware\.
• 命名空间是正确的
• composer dump-autoload 不会解决问题

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;

然后删除"App/Http/Middleware/xxx.php"并composer.json运行composer du

如果您使用的是 5.2.27 及更高版本，您还需要从路由文件中删除 Web 中间件：

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