是否有人有此扩展的工作示例。 我说的是：

我正在寻找Yii应用程序基本

我安装并正常工作，但我不知道如何配置角色和规则

创建自定义模型AccessRules.php

<?php 
namespace app\models;


class AccessRules extends \yii\filters\AccessRule
{

    /**

     */
    protected function matchRole($user)
    {
        if (empty($this->roles)) {
            return true;
        }
        foreach ($this->roles as $role) {
            if ($role === '?') {

                if ($user->getIsGuest()) {
                    return true;
                }
            } elseif ($role === '@') {
                if (!$user->getIsGuest()) {
                    return true;
                }
            // Check if the user is logged in, and the roles match
            } elseif (!$user->getIsGuest() && (int)$role === $user->identity->user_role) {
               return true;
            }
        }

        return false;
    }
}
