如何将Firebase消息发送到项目中的特定应用程序？ [英] How to send Firebase message to specific application in project?

问题描述

我有一个基于firebase的疑问。它允许为单个项目添加多个应用程序。我已经添加了App1，App2和App3。我如何才能单独向App1发送通知？服务器密钥与这3个应用相同。

解决方案

在Firebase控制台的通知面板中，您可以发送通知消息到特定的应用程序。但是，在Firebase Cloud Messaging API中不支持这种定位。

通过为每个应用定义特定的属性，您可以轻松地模拟这些行为： / topics / apps-app1 ， / topics / apps-app2 ，然后让每个应用都订阅自己的主题，并且您可以将每个应用的用户定位到一个FCM服务器密钥。

I have a doubt based on firebase. It allows to add multiple application for a single project. I have added App1, App2 and App3. How can I send a notification to App1 alone? Server key is the same for those 3 apps.

解决方案

In the Notifications panel in the Firebase Console, you can send a notification message to a specific app. But there is no support for such targeting in the Firebase Cloud Messaging API.

You can easily emulate the behavior though, by defining a specific property for each of your apps: /topics/apps-app1, /topics/apps-app2, etc. Then have each app subscribe to its own topic and you can target the users of each app with a single FCM server key.
