收到后更改通知内容

Question

是否可以在通知内容显示在设备上之前对其进行更改？例如：我有一个名为John的用户，该用户订阅了一个名为food的主题，我向该主题发送了带有标题为“ Good morning username”的推送通知，但设备将显示“ Good morning John”

我想知道这在Android或iOS上是否可行，以及如何实现

对于 Android ， 是的，可以通过覆盖onMessageReceived中的FirebaseMessagingService

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // Check your notification is not null and subcribed to `food` topic.
    if(remoteMessage.getFrom() == "food" &&
        remoteMessage.getNotification() != null){ 
        String title = remoteMessage.getNotification().getTitle(); // Title from the notification. E.g `Good morning`

        // Get the `username` of the user stored in the device. Use SharedPreference.

        String message = title + " " + username; // "Good morning username"
        // Call your notification here.
    }
}
