Firebase 云函数 onWrite 子值

Question

我正在使用 Firebase Cloud Function 在实时数据库触发事件时发送 FCM。如何获取 {followerUid} 中子项 ('uid') 的值？

exports.sendFollowerNotification = functions.database.ref('/followers/{followedUid}/{followerUid}').onWrite(event => {
  const followerUid = event.params.followerUid;
  const followedUid = event.params.followedUid;

Answer 1

我知道你在找什么......

var uid = event.data.val();
var uid1 = String(uid);

将此 uid1 添加到标题或正文

const payload = {
      notification: {
        title: paypes
        body:  uid1
      }
    };
