Solve the problem that ThinkPHP6 prompts that the controller does not exist

The following tutorial column of thinkphp will introduce to you the solution to the problem that ThinkPHP6 prompts that the controller does not exist. I hope it will be helpful to friends in need!

ThinkPHP 6 prompts that the control controller does not exist

---

thinkphp 6 defaults to single application mode, when multiple applications are required , you need to install the multi-application mode extension think-multi-app.

composer require topthink/think-multi-app

Then delete the app\controller directory that comes with the framework and create the application directory you need.

For example: \app\index\controller\Index.php

<?php
namespace app\index\controller;use app\BaseController;class Index extends BaseController
{    public function index()
    {        return 'hello index';
    }
}

Access this method: http://www.study_tp6.com/public/index.php/index/index/index

Result prompt: The controller does not exist app\controller \index

Find the reason:

1. The think-multi-app extension was installed according to the official documentation, and it was prompted that the installation was successful.

2. The namespace of the controller is not written correctly.

3. The access path is the same as the directory name, controller, and method name, and the access address is correct.

4. It is said on the Internet that in the configuration file config/app.php, change 'auto_multi_app' => flase, to true,

But the version I am using is ThinkPHP 6.0. 4. There is no such parameter in the configuration file. I tried adding it but it didn’t work.

5. Is there something wrong with the downloaded framework? I redownloaded the framework and reinstalled the multi-application extension, but it still didn't work.

Solution:

Thanks [ikgade] for sharing in the official comments, gave it a try, and solved this pitfall.

This is the author's idea and plan:

为什么提示 “控制器不存在:app\controller\Admin”？
因为安装多应用模式扩展执行的指令没有生效 php think service:discover 自动注册扩展包的系统服务。
为什么自动注册拓展包服务失败，详见代码：
vendor/topthink/framework/src/think/console/command/ServiceDiscover.php
第34行代码$package['extra']['think']['services']为空，导致生成自动注册服务文件
services.php 中没有注册的代码。
天坑！
怎么解决呢？
首先找到你加入的拓展，在这里：
vendor/composer/installed.json
然后把所有的$package['extra']['think']['services']复制粘贴到services中，或者修改以下文件的代码：
vendor/topthink/framework/src/think/console/command/ServiceDiscover.php

Copy the services value in vendor/composer/installed.json to the array of vendor/services.
