Lumen/Laravel 错误 - ReflectionException：Class App\Http\Controllers\Photos\TestController 不存在
Lumen/Laravel Error - ReflectionException: Class App\Http\Controllers\Photos\TestController does not exist
我正在尝试组织我的项目 (lumen / laravel)，使我的控件位于子文件夹中以获得更多控制权。我按照官方流明指南（https://lumen.laravel.com/docs/6.x/controllers）但是问题如下：
在我的路由文件 (routes/web.php) 中，我有以下代码：
<?php
$router->get('test', 'Photos\TestController@show');
而我的控制器位于路径 app/Http/Controllers/Photos/TestController.php 中并具有以下代码：
<?php
namespace App\Http\Controllers;
class TestController extends Controller
{
public function show(){
return "hello";
}
}
但是在向 url http://localhost/myproject/public/test 发出请求时，我收到以下消息：
Click to view
并且在我的日志文件 (storage/logs/lumen-xx-xx-xx.log) 中出现以下错误：

我想知道我做错了什么，因为我看了好几遍文档还是找不到解决办法，我也在网上搜了下也没有人问过。非常感谢您。
由于您的控制器位于子文件夹中，因此您还需要通过添加子文件夹来更改它的命名空间，如下所示。
namespace App\Http\Controllers\Photos
然后能够将您的控制器扩展为控制器 class。把这段代码也放上去。
use App\Http\Controllers\Controller
