Question

那时通知到设备时，会有一个数据来自通知，但我希望从该remotemessage.it中获取特定数据。这是我的远程消息数据捆绑包[{google.delivered_priority = high，google.sent_time = 1550486789753，google.ttl = 2419200，google.original_priority = high，gcm.notification.e = 1，intent = {“ notification_from”：1，“声音”：1， “ vibrate”：1，“ body”：“您的新访客登机。我可以批准进入此访客”，“ title”：“ SocietyWerx”}，gcm.notification.vibrate = 1，gcm.notification.sound = default ，gcm.notification.title = SocietyWerx，来自= 4178695373，gcm.notification.sound2 = 1，google.message_id = 0：1550486789763843％c9737a40c9737a40，gcm.notification.body =您的新访客来了。我可以批准进入此访客吗？，gcm.notification.notification_from = 1，google.cae = 1，}]

下面是我的消息传递服务代码。我需要从此数组中的此参数获取notification _。

remoteMessage.getData()

获取用于推送通知的数据有效载荷。

String messageID = remoteMessage.getData().get("messageID");
String message = remoteMessage.getData().get("message");

您可能会获得像这样的值。
