Firebase推送通知和FCM邮件有什么区别？ [英] What is the difference between Firebase push-notifications and FCM messages?

问题描述

Heloo，我正在构建一个应用程序，通过Firebase控制台使用推送通知。我想知道简单的推送通知和云消息有什么区别？
是否云消息传递的消息是数据消息（具有密钥和值），通知只是文本而没有键和值？我是对吗？

解决方案

Firebase API有两种类型的消息，他们称之为：

• 通知



$ h










$只有当您的应用程序处于后台/终止或者被传送到 onMessageReceived（）时， / code>方法（如果您的应用程序位于前景中）。



  {
notification：{body：Hi} 
} 
  







2. 数据有效负载 - 无论您的应用程序处于forground或background或杀死状态，这些消息将始终传递到 on MessageReceived（）方法。



示例：

< pre $ {
data：{message：Hi，whatever_key：value}
}

重要提示：您无法从 Firebase Console 控制台仅传递通知消息。但是使用API​​，您可以发送这两种类型的消息。
$ b

要发送数据有效负载消息，您必须发出一个curl请求：



HTTP POST请求





  https://fcm.googleapis.com/fcm/send 
 Content-Type：application / json 
授权：key = AIzaSyZ-1u ... 0GBYzPu7Udno5aA 
 
 {data：{
score：5x1，
time ：15:10
}，
to：bk3RNwTe3H0：CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1 ...
} 
  

您可以从Firebase控制台获取服务器密钥（AIzaSyZ-1u ... 0GBYzPu7Udno5aA）：您的项目 - >设置 - >项目设置 - >云消息传递 - >服务器密钥


Heloo, I am building an app where I am using push notifications via Firebase Console. I want to know what is a difference between simply push-notification and cloud message? Is it that messages from cloud messaging are data messages(have key and value) and notifications are just text without key and value?Am I right?

解决方案

Firebase API has two types of messages, they call them:

• notification
• data

Explanation:

1. notification - messages that goes directly to Android's Notification tray only if your application is in background/killed or gets delivered to onMessageReceived() method if your app is in foreground.

Sample:

{
    "notification" : { "body" : "Hi"}
}

2. data payload - Doesn't matter whether your application is in forground or background or killed, these messages will always be delivered to onMessageReceived() method.

Sample:

{
    "data" : { "message" : "Hi", "whatever_key": "value"}
 }

IMPORTANT : You can't send data payload messages from Firebase Console, Console only delivers notification message. However using API you can send both type of messages.

To send a data payload message you have to make a curl request:

HTTP POST Request

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

You can get the server key (AIzaSyZ-1u...0GBYzPu7Udno5aA), from firebase console: Your project -> settings -> Project settings -> Cloud messaging -> Server Key
