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:

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

并触发FirebaseMessagingService的方法OnMessageReceaved().许多设备(尤其是华为和小米)都竭尽全力杀死后台服务，以防止电池耗尽.因此，FirebaseMessagingService并不是处理通知的最佳方法.

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.

第二种类型是
数据消息:

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

此类型由系统托盘处理，因此您无需运行任何服务即可获取通知.它更方便的方法，但是据我所知，它不能通过控制台来实现.

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.
