php - Lumen/Laravel 错误 - ReflectionException : Class App\Http\Controllers\Photos\TestController does not exist

Question

我试图以这样一种方式组织我的项目(lumen/laravel)，以便我的控件位于子文件夹中以获得更多控制。我正在遵循官方流明指南( https://lumen.laravel.com/docs/6.x/controllers )，但问题如下:

在我的路由文件 (routes/web.php) 中，我有以下代码:

<?php

$router->get('test', 'Photos\TestController@show');

我的 Controller 位于路径 app/Http/Controllers/Photos/TestController.php 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 发出请求时 http://localhost/myproject/public/test我收到以下消息:

Click to view

在我的日志文件 (storage/logs/lumen-xx-xx-xx.log) 中，我收到以下错误:

我想知道我做错了什么，因为我看了好几遍文档，仍然找不到解决方案，我也搜索了互联网，没有人问过它。非常感谢您提前。

由于您的 Controller 位于子文件夹中，因此您还需要通过添加它的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 Controller 扩展到 Controller 类。也把这个代码。

use App\Http\Controllers\Controller
