具有 Firebase 实时数据库的云功能未触发 onCreate 且未发送 FCM 通知

Question

我正在尝试根据 RealtimeDatabase 的 onCreate 事件自动发送通知，但是 function 从不触发并且从不记录任何内容。

代码：

// The Cloud Functions for Firebase SDK to create Cloud Functions and set up triggers.
const functions = require('firebase-functions');

// The Firebase Admin SDK to access Firestore.
const admin = require('firebase-admin');
admin.initializeApp();

exports.notificationOnArticleCreate = functions.database.ref().onCreate((snapshot, context) => {
  const payload = {
    notification: {
      title: 'cloud function demo',
      body: 'this is a test notification'
    }
  };
  
  admin.messaging().send(payload).then((response) => {
      console.log('Successfully sent message:', response);
      return {success: true};
    }).catch((error) => {
      return {error: error.code};
    });

    console.log('test test');
})

我很惊讶这甚至编译/部署： functions.database.ref().onCreate 。

您需要指出创建节点的路径，例如

functions.database.ref("/messages/{message}").onCreate(...
