thinkphp6.0控制器中间件和initialize()的执行顺序

结论：thinkphp6.0控制器中间件，在initialize()之后执行

测试：

1、首先创建一个tp6的新项目

composer create-project topthink/think tp

2、安装多应用模式扩展

composer require topthink/think-multi-app

3、创建一个新应用

php think build index

4、创建一个中间件

php think make:middleware index@Test

5、在app\index\middleware\Test.php中添加测试代码

<?php
declare (strict_types = 1);

namespace app\index\middleware; use think\Response;

class Test
{
    /**
     * 处理请求
     *
     * @param \think\Request $request
     * @param \Closure       $next
     * @return Response
     */
    public function handle($request, \Closure $next)
    {
        $request->test_name = 'hello world';
        dump('中间件');
        return $next($request);
    }
}

6、在app\index\controller\Index.php中添加测试代码

<?php
declare (strict_types = 1);

namespace app\index\controller;

use app\BaseController;
use app\index\middleware\Test;
use app\Request;
use think\App;

class Index extends BaseController
{
    protected $middleware = [
        Test::class,
    ];

    public function initialize()
    {
        parent::initialize();
        dump('initialize:' . $this->request->test_name);
    }

    protected function getTestName()
    {
        dump($this->request->test_name);
    }

    public function index(Request $request)
    {
        $this->getTestName();
        echo 'index';
    }

}

7、在项目根目录下面执行：

php think run

8、在浏览器中访问http://127.0.0.1:8000

看到如下结果：

由此可知tp6的控制器中间件，在initialize()之后执行，在initialize()中是获取不到中间件中设置的test_name的
