Yii 框架和动态子域

Question

我想知道 Yii 框架如何根据 URL 中传递的子域将请求发送到正确的控制器：

www.mysystem.com -> 此请求由我系统中特定模块的默认控制器处理。

但是当用户访问他们的商店时，他们将使用 URL：storename.mysystem.com。 （有很多不同的店名）

我想知道在 Yii 中哪里可以找到配置来设置哪个模块/控制器将处理这个请求。

谢谢你。

这是我的 Yii2 配置

main.php

    <?php
$params = array_merge(
    require(__DIR__ . '/../../common/config/params.php'),
    require(__DIR__ . '/../../common/config/params-local.php'),
    require(__DIR__ . '/params.php'),
    require(__DIR__ . '/params-local.php')
);

$host = (!empty($_SERVER['HTTP_HOST']))?$_SERVER['HTTP_HOST']:$_SERVER['SERVER_NAME'];
$segments = explode('.',$host);
defined('SUBDOMAIN') or define('SUBDOMAIN', strtolower($segments[0]));

return [
    'id' => 'app-backend',
    'basePath' => dirname(__DIR__),
    'controllerNamespace' => 'backend\controllers',
