Question

我正在使用Firebase Cloud函数通过Node js和我的应用程序在Swift上进行通知

这是我的有效载荷

  var payload = {
       notification: {
         title: (goOfflineTimePeriod,"Inactive for minutes you are now offline"),
         body: "Time period for inactive log off can be changed in your settings"

尽管我的通知我的通知仅显示为； “您处于离线状态的几分钟内处于非活动状态”，“可以在您的设置中更改非活动注销的时间段”

所以变量； goOfflineTimePeriod没有显示在通知中

我只是Node JS的新手，是否有一个原因为什么通知中未显示“ goOfflineTimePeriod”？

这是我的全节点js功能代码；

exports.goOfflineAlert = functions.firestore
.document('/goneOffline/{uid}')
.onCreate((snap, context) => {

  var db = admin.firestore();
  var uid = context.params.uid;
  const newValue = snap.data();
  const goOfflineTimePeriod = newValue.goneOffline;

console.log('uid is',uid)

  var cityRef = db.collection('Users').doc(uid);
 var getDoc = cityRef.get()
     .then(doc => {
       if (!doc.exists) {
         return console.log('No such document!');
       } else {

          const newValue = doc.data();
          const age = newValue.Age;
          const name = newValue['Display Name'];
          const fcmToken = newValue.fcmToken;
          const goOfflineTimePeriod = newValue.goOfflineTimePeriod;


     console.log('Document data:', doc.data(),age,fcmToken,name,goOfflineTimePeriod);

     var payload = {
       notification: {
         title: (goOfflineTimePeriod,"Inactive for minutes you are now offline"),
         body: "Time period for inactive log off can be changed in your settings"



       }
     }

, operator不会在JavaScript中连接字符串，但是会返回第二个操作数。相反，您应该使用+或模板字符串。例如：

title: goOfflineTimePeriod+" Inactive for minutes you are now offline",

测试时，节点Js值未显示在通知中
