推荐答案

FCM 通知有两种类型:通知消息和数据消息.

There are 2 types of FCM notifications: Notification message and Data message.

通知消息如下所示:

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "title":"Portugal vs. Denmark",
      "body":"great match!"
    }
  }
}

并触发 FirebaseMessagingService 的 OnMessageReceaved() 方法.许多设备(尤其是华为和小米)试图尽一切努力终止后台服务以防止电池耗尽.所以 FirebaseMessagingService 并不是处理通知的最佳方式.

and triggers method OnMessageReceaved() of FirebaseMessagingService. Many devices (especially Huawei and Xiaomi) try to do everything to kill background services to prevent battery drain. So the FirebaseMessagingService isn't the best way to handle notifications.

第二种是
数据信息:

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "data":{
      "Nick" : "Mario",
      "body" : "great match!",
      "Room" : "PortugalVSDenmark"
    }
  }
}

此类型由系统托盘处理，因此您不需要运行任何服务来获取通知.它更方便的方法，但据我所知，它无法通过控制台实现.

This type is handled by the system tray, so you don't need any of service running to get the notification. Its much more convenient method, but as far i know, it can't be achieved with the console.

您可能需要服务器 API 来发送数据消息.

You would probably need server API to send Data message.
