如何基于用户属性用户发送Firebase云消息传递通知？

Question

Like it's said here I know it's not possible to send notification by user property with the HTTP v1 API.

But is it possible to use an alternative way to do this? Like, call a cloud function from my backend that takes the message and the user property in parameter and send the notification.

Answer 1

Have a look at the official Firebase sample which "demonstrates how to send a Firebase Cloud Messaging (FCM) notification from a Realtime Database triggered Function".

Users sign into the app and are requested to enable notifications on their browsers. If they successfully enable notifications the device token is saved into the Realtime Database.

.....

The sample also features a Web UI to experience the FCM notification.

All the code and instructions are here: https://github.com/firebase/functions-samples/tree/Node-8/fcm-notifications
