我正在尝试部署一个Firebase云函数，该函数向其关联的收件人发送x条文本消息。当对“发送”实时数据库引用进行更新时，我的iOS应用程序中会触发该功能，表明用户已按下“发送”按钮

我的火基结构是

  {
  "user1uid": {
    "send": false
    "messagesToSend": {
      "messageuid1": {
         "messageText": "What's for dinner?",
         "recipientNumber": "+18017378888",
      }
      "messageuid2:
         "messageText": "Who won the Cowboys game?",
         "recipientNumber": "+18017377787",
      }
   }
   "user2uid": {
    "send": false
    "messagesToSend": {
      "messageuid1": {
         "messageText": "What's for dinner?",
         "recipientNumber": "+18017378888",
      }
      "messageuid2:
         "messageText": "Who won the Cowboys game?",
         "recipientNumber": "+18017377787",
      }
   }
}

我的代码目前只发送一条消息，我不确定如何正确地迭代每个用户的messagesToSend节点并发送其中的所有消息

我一直在努力学习教程。我查看了以下堆栈溢出响应，但无法从中破译或导出解决方案：

我发送一条消息的index.js代码如下：

const functions = require('firebase-functions');

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

const twilio = require('twilio')

const accountSid = functions.config().twilio.sid;
const authToken  = functions.config().twilio.token;

const client = new twilio(accountSid, authToken);

const twilioNumber = functions.config().twilio.number;


// Start cloud function
exports.sendSecrets = functions.database
       .ref('/{uid}/send')
       .onUpdate((change,context) => {

    const uid = context.params.uid;

    return admin.database().ref(uid+'/messagesToSend').once('value').then(snapshot => {

      snapshot.forEach(function(childSnapshot) {

          var key = childSnapshot.key;
          var messageData = childSnapshot.val();
          **if (messageData.sanitized) return true;**
          var message = messageData.messageText;
          var phoneNumber = messageData.recipientNumber;

          const textMessage = {
            body: `From My App - ${message}`,
            from: twilioNumber, // From Twilio number
            to: phoneNumber  // Text to this number
          }
          return client.messages.create(textMessage)
        })
        **return snapshot.ref.toString();**
    });
});

const functions = require('firebase-functions');

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

const twilio = require('twilio')

const accountSid = functions.config().twilio.sid;
const authToken  = functions.config().twilio.token;

const client = new twilio(accountSid, authToken);

const twilioNumber = functions.config().twilio.number;


// Start cloud function
exports.sendSecrets = functions.database
       .ref('/{uid}/send')
       .onUpdate((change,context) => {

    const uid = context.params.uid;

    return admin.database().ref(uid+'/messagesToSend').once('value')
    .then(snapshot => {

      const promises = [];

      snapshot.forEach(function(childSnapshot) {

          var key = childSnapshot.key;
          var messageData = childSnapshot.val();
          //**if (messageData.sanitized) return true;**
          var message = messageData.messageText;
          var phoneNumber = messageData.recipientNumber;

          const textMessage = {
            body: `From My App - ${message}`,
            from: twilioNumber, // From Twilio number
            to: phoneNumber  // Text to this number
          }

          promises.push(client.messages.create(textMessage));
      })

      return Promise.all(promises);
    })
    // Edits made below to parentheses/brackets
    .then(results => {
      //Do whatever you want !!
      // e.g. print the results which will be an array of messages
      // (see https://www.twilio.com/docs/libraries/node#testing-your-installation)
    })            
});

....
     return Promise.all(promises);
   })
});

请注意，两端标有**的行表示我知道我需要根据收到的错误消息返回某些内容，这些错误消息指示“Each then（）应返回值或抛出”。

我假设您使用的是使用承诺的

twilio节点

库：

由于要并行发送多条消息，因此必须使用

Promise.all（）

，如下所示：

const functions = require('firebase-functions');

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

const twilio = require('twilio')

const accountSid = functions.config().twilio.sid;
const authToken  = functions.config().twilio.token;

const client = new twilio(accountSid, authToken);

const twilioNumber = functions.config().twilio.number;


// Start cloud function
exports.sendSecrets = functions.database
       .ref('/{uid}/send')
       .onUpdate((change,context) => {

    const uid = context.params.uid;

    return admin.database().ref(uid+'/messagesToSend').once('value').then(snapshot => {

      snapshot.forEach(function(childSnapshot) {

          var key = childSnapshot.key;
          var messageData = childSnapshot.val();

            to: phoneNumber  // Text to this number
          }
          return client.messages.create(textMessage)
        })
        **return snapshot.ref.toString();**
    });
});

const functions = require('firebase-functions');

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

const twilio = require('twilio')

const accountSid = functions.config().twilio.sid;

const client = new twilio(accountSid, authToken);

const twilioNumber = functions.config().twilio.number;


// Start cloud function
exports.sendSecrets = functions.database
       .ref('/{uid}/send')
       .onUpdate((change,context) => {

    const uid = context.params.uid;

    return admin.database().ref(uid+'/messagesToSend').once('value')
    .then(snapshot => {

      const promises = [];

      snapshot.forEach(function(childSnapshot) {

          var key = childSnapshot.key;
          var messageData = childSnapshot.val();
          //**if (messageData.sanitized) return true;**
          var message = messageData.messageText;
          var phoneNumber = messageData.recipientNumber;

          const textMessage = {
            body: `From My App - ${message}`,
            from: twilioNumber, // From Twilio number
            to: phoneNumber  // Text to this number
          }

          promises.push(client.messages.create(textMessage));
      })

      return Promise.all(promises);
    })
    // Edits made below to parentheses/brackets
    .then(results => {

谢谢你，勒诺，我刚刚编辑了一些括号/括号，毫无疑问，你打得很快。谢谢你的帮助。@northsydneybears很高兴我能帮忙。如果你认为这有帮助的话，你可以考虑我的回答。谢谢考虑过了，做过了，再次感谢你。你知道我会打什么电话把所有发送的信息数据打印出来吗？（例如，to、from和messageText/body？）我知道它是console.log，但我尝试了

。然后（（message）=>console.log（message））并且它只返回收件人的号码。@northsydneybears抱歉，我不太了解Twilio SDK和API。但是根据doc（），create（）
方法返回一个用消息
对象解析的承诺。这类对象的API文档如下：。除其他属性外，还有一些from

属性。Promise.all（）
返回的消息将包含在results
