Alexa技能循环:基于用户的输入，Alexa会说些什么。

Question

我的技能：做一个果汁建议，当用户说一个状态时，Alexa会根据这个状态给出一个果汁建议。状态和果汁对被存储在一个数组中。

挑战：目前，我的技能只执行一次。有什么方法可以让我有一个循环，在Alexa提出建议之后，Alexa会再次问这个问题，然后等待用户的响应吗？附随的是我用我的技巧所拥有的密码。谢谢。

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

const APP_ID = undefined;

const skillData = [
    {
        state: "FLORIDA",
        suggestion: "My suggestion for Florida is organic orange juice by Naked"
    },
    {
        state: "CALIFORNIA",
        suggestion: "My suggestion for California is pomegrante by POM!!"
    },
    {
        state: "NEW JERSEY",
        suggestion: "My suggestion for Jersey is blueberry by Jersey Fresh"
    }
];

var number = 0;
while(number<3){
var handlers = {
  'LaunchRequest': function () {

    this.emit(':ask', 'I can suggest a juice from any state in the United States. What state would you like a juice suggestion for?', 'Tell me a state name and I will suggest a local juice from there.');
  
      
    },
  'MakeSuggestion': function() {
      var stateSlot = this.event.request.intent.slots.state.value;

      this.emit(':tell', getSuggestion(skillData, 'state', stateSlot.toUpperCase()).suggestion);

  },

  'AMAZON.StopIntent': function () {

exports.handler = function(event, context){
  var alexa = Alexa.handler(event, context);
  alexa.registerHandlers(handlers);
  alexa.execute();

function getSuggestion(arr, propName, stateName) {
  for (var i=0; i < arr.length; i++) {
    if (arr[i][propName] == stateName) {

Answer 1

在您的MakeSuggestion函数中，使用ask而不是tell，并再次附加问题：

this.emit(':ask', getSuggestion(skillData, 'state', stateSlot.toUpperCase()).suggestion + '. Tell me another state and I give you another suggestion!');

Answer 2

是的，您可以通过使用state来完成这一任务，而不是使用":tell"，您可以通过":ask“来响应，这样alexa麦克风就可以保持开放状态以进行用户交互。
