I have error Unknown Method

Calling unknown method: yii\web\Application::params()

Model:

public static function isSecretKeyExpire($key)
{
    if (empty($key))
        return false;
    $expire = Yii::$app->params('secretKeyExpire');
    $parts = explode('_', $key);
    $timestamp = (int) end($parts);

Yii::app()->params['secretKeyExpire']
