【问题描述】：
当您说“核心”控制器时，我理解您是指“基本”控制器，在 CI v3 中通常被命名为 MY_Controller。如果这就是您所要求的，那么由于命名空间和自动加载器，在 v4 中实际上要容易得多。此外，不需要使用像MY_ 这样的前缀。
这就是它是多么容易。 “基础”控制器...
文件：/application/Controllers/Base.php
<?php namespace App\Controllers;
class Base extends \CodeIgniter\Controller
{
//your code here
}
然后扩展上述内容以创建任何其他控制器
文件：/application/Controllers/Home.php
<?php namespace App\Controllers;
class Home extends \App\Controllers\Base
{
// Your code here
}
Home 控制器将继承您在Base 中定义的所有属性和方法。

好的，非常感谢@DFriend。我会努力的！！
你不需要创建另一个核心控制器，已经提供了一个核心控制器，即BaseController。 您只需将其扩展到您的选择

试试这个
<?php namespace App\Core;
use CodeIgniter\Controller;
class Home extends Controller
{
}

查看我的代码
