I am wondering if I can use web push notifications to update a web page without displaying a notification for the user to interact with. Essentially I want to refresh data after an event on the server.

如果可以，是否还需要获得用户的许可才能发送这些推送更新?

If this is possible, is it still necessary to receive permission from the user to send these push updates?

推荐答案

是的，您可以在不显示通知的情况下发送推送消息，但 Firefox 和 Chrome 对不可见"推送消息的原始数量和您发送它们的速率.

Yes, you can send push messages without showing a notification, but there are limitations on both Firefox and Chrome on the raw number of "invisible" push messages and the rate at which you send them.
