Lumen/Laravel 錯誤 - ReflectionException: Class App\\Http\\Controllers\\Photos\\TestController 不存在

Question

我正在嘗試以這樣一種方式組織我的項目（lumen / laravel），以便我的控件位於子文件夾中以進行更多控制。 我正在關注官方流明指南（ https://lumen.laravel.com/docs/6.x/controllers ），但問題如下：

在我的路由文件 (routes/web.php) 中，我有以下代碼：

<?php

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

我的控制器位於路徑 app/Http/Controllers/Photos/TestController.php 並具有以下代碼：

<?php

namespace App\Http\Controllers;

class TestController extends Controller
{
  public function show(){
    return "hello";
  }
}

但是在向 url http://localhost/myproject/public/test發出請求時，我收到以下消息：

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

我想知道我做錯了什么，因為我看了好幾遍文檔，仍然找不到解決方案，我也搜索了互聯網，沒有人問過它。 非常感謝您提前。

Answer 1

由於您的控制器位於子文件夾中，因此您還需要通過添加它的子文件夾來更改它的命名空間，如下所示。

namespace App\Http\Controllers\Photos

然后能夠將您的控制器擴展到控制器類。 也把這個代碼。

use App\Http\Controllers\Controller
