问题描述

我已经使用 Firebase 创建了推送通知服务,我可以向所有或单个具有 FCM id 的用户发送通知,但我不知道如何发送给特定用户.

I Have created push notification service using Firebase and I can send notification to either all or single user having FCM id, but I have no idea how to send to specific user.

服务器面板也不是为处理推送通知而创建的,如果有任何建议,会有更多帮助.

Also server panel is not created for handling push notification handling If any suggestion for that is there will help more.

推荐答案

Firebase 云消息传递 (FCM) 主题消息传递允许您将消息发送到已选择加入特定主题的多个设备.基于发布/订阅模型,主题消息支持每个应用程序的无限订阅,即您的组附加到特定主题,如新闻组、体育组等.

Firebase Cloud Messaging (FCM) topic messaging allows you to send a message to multiple devices that have opted in to a particular topic. Based on the publish/subscribe model, topic messaging supports unlimited subscriptions for each app i.e your group is attached to specific topic like news group,sports group etc.

FirebaseMessaging.getInstance().subscribeToTopic("news");

取消订阅unsubscribeFromTopic("news")

从服务器端,您需要设置特定主题,即像这样的一组用户:

From Server side you need to set up for specif topic i.e a group of user like this:

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

{
  "to": "/topics/news",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!",
   }
}

"/topics/news" 这将向订阅新闻主题的人群发送通知

"/topics/news" This will send notification to group of people who have subsribe the news topic
