javascript - Expo 推送通知检测

Question

我如何检测即将到来的通知并在应用程序关闭时进行一些更改...

我正在使用expo-notifications https://docs.expo.io/versions/latest/sdk/notifications/

Answer 1

您的应用在关闭/后台运行时不会收到通知，直到用户与其交互。

来自Expo 38 release notes :

If the notification is triggered while the app is in background,

• it’s presented immediately

• the application is not informed of this

If the notification is triggered while the app is in foreground,

• the application not only receives immediate information about this, but…

• it can also decide at runtime whether to display a heads-up alert or play a sound! (For more information see the Notification Handler documentation.)

来自Notifications overview ，有 2 个监听器:

addNotificationReceivedListener - This listener is fired whenever a notification is received while the app is foregrounded

addNotificationResponseReceivedListener - This listener is fired whenever a user taps on or interacts with a notification (works when app is foregrounded, backgrounded, or killed)

Notifications SDK也是一个很好的引用。
