使用 Alexa-SDK 如何让 this.emit() 方法返回 JSON 数组中的多个对象？

Question

我正在尝试使用 emit() 方法从 JSON 数组中获取多个帐户 ID。发射方法是从 Alexa-SDK 定义的。问题是它只发出一个值而不是全部。如何让 emit() 方法返回 JSON 数组中的两个对象值？

这是我的代码 sn-p：

'use strict';

const Alexa = require('alexa-sdk');

const handlers = {
  'LaunchRequest': function() {
    this.emit(':tell', 'sure');
    this.emit('getEmployeeInfoIntent');
  },
  'getEmployeeInfoIntent': function() {
    var empinfoData = {
    "employees": [{
        "account_id": 8675309
      },{
        "account_id": 54321
      }]
    };
    for (var i in empinfoData) {
      var employeeInfo = empinfoData[i].account_id;
      this.emit(':tell', 'The accounts available are id number' + employeeInfo);
      //return only 8675309 but I want 8675309 and 54321
    };
  }
}; ///end of handler

exports.handler = (event, context) => {
  const alexa = Alexa.handler(event, context);
  alexa.APP_ID = APP_ID;
  alexa.registerHandlers(handlers);
  alexa.execute();
};

var objtwo = {
  "employees": [{
    "account_id": 8675309
  },{
    "account_id": 54321
  }]
}

// mythis variable is defined globally
var mythis = this;

function getJSONArray() {
  //var reqresponse = this.responseText;
  //var objtwo = JSON.parse(reqresponse); 
  var empinfoData = objtwo.employees;
  var allIds = [];
  for (var i of empinfoData) {
    var employeeInfo = i["account_id"];
    allIds.push(employeeInfo);
  };
  return allIds;
};
console.log(getJSONArray());

将 emploeeInfo 保存到一个数组中，并在循环后发出该数组。
