Yii2 - 如何在用户身份中设置动态 authTimeout?

问题描述

这里，我扩展了Yii2的User身份.

Here, I have extended User Identity of Yii2.

这是我的配置.

'user' => [
            'identityClass' => app\models\UserMaster::class,
            'enableAutoLogin' => false,
            'loginUrl' => ['/auth/login'],
            'authTimeout' => 86400
        ],

这里，我静态定义了 authTimout.但是，我想要做的是我想从数据库中获取超时值并将其设置在 authTimeout 中.

Here, I have defined authTimout statically. But, What I want to do is that I want to fetch timeout value from database and set it in authTimeout.

谢谢.

推荐答案

您可以在处理请求之前使用事件设置authTimeout:

You can use event to set authTimeout before request will be handled:

'as beforeRequest' => [
    'class' => function (Event $event) {
        /* @var $app \yii\web\Application */
        $app = $event->sender;
        $app->getUser()->authTimeout = (new Query())
            ->select('value')
            ->from('{{%settings}}')
            ->where('name = :name', ['name' => 'authTimeout'])
            ->scalar($app->getDb());
    }
],

但可能更清晰的方法是创建自定义组件并在 init() 中处理它.

class WebUser extends \yii\web\User {

    public function init() {
        parent::init();

        $this->authTimeout = (new Query())
            ->select('value')
            ->from('{{%settings}}')
            ->where('name = :name', ['name' => 'authTimeout'])
            ->scalar();
    }
}

然后在您的配置中使用新组件:

Then use new component in your config:

'components' => [
    'user' => [
        'class' => WebUser::class,
        'identityClass' => app\models\UserMaster::class,
        'enableAutoLogin' => false,
        'loginUrl' => ['/auth/login'],
    ],
    // ...
],
