推荐答案

您可以使用 Yii::$app->request->referrer 返回用户所在的最后一页.

You could use Yii::$app->request->referrer which returns the last page the user was on.

用法很简单:

return $this->redirect(Yii::$app->request->referrer);

您还需要考虑到 referrer 可以是 null:

You need also take into account that referrer can be null:

return $this->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);

请参阅文档.
