亚马逊Alexa Skill

Question

我想问alexa各种各样的问题，最后我想让它问“你还有什么想知道的吗？”当我说“是”（yes是工作建议）时，它应该根据我的意图来建议我。就像我在

IncityIntent:

    'InCityIntent': function () {
        speechOutput = '';


speechOutput = "The atmosphere in the city is beautiful. Is there anything else you would like to know";
        this.emit(":ask", speechOutput, speechOutput);


'YesIntent': function () {
        speechOutput = '';
/*when the user say yes, he should get this output*/  
            speechOutput = You can learn more about city by trying, alexa what are the best places in the city";
            this.emit(":tell",speechOutput, speechOutput);

FoodIntent:

    'FoodIntent': function () {
        speechOutput = '';


speechOutput = "Food in the city is delicious. Is there anything else you would like to know";
        this.emit(":ask", speechOutput, speechOutput);

'YesIntent': function () {
        speechOutput = '';
/*change in response here*/
            speechOutput = You can learn more about food by trying, alexa what are the best restaurants in the city";
            this.emit(":tell",speechOutput, speechOutput);

Answer 1

首先，不要创建自定义的YesIntent和nocontent，而是使用AMAZON。YesInt和亚马逊。无内容。如果你愿意，你总是可以在这些预先定义的意图中添加话语。

你的问题可以通过几种方式解决。

使用sessionAttributes:
添加一个previousIntent属性，或者在收到初始请求时，在sessionAttributes中跟踪对话，比如说InCityIntent。在你的亚马逊上。YesInt或亚马逊。NoIntent处理程序检查之前的意图，并相应地回复。

 'InCityIntent': function () {
       const speechOutput = "The atmosphere in the city is beautiful. Is there anything else you would like to know";
       const reprompt = "Is there anything else you would like to know";
       this.attributes['previousIntent'] = "InCityIntent";
       this.emit(":ask", speechOutput, reprompt);
  }

 'Amazon.YesIntent': function () {
     var speechOutput =  "";
     var reprompt = "";
     if (this.attributes 
        && this.attributes.previousIntent
        && this.attributes.previousIntent === 'InCityIntent' ) {
        speechOutput = "You can learn more about city by trying, Alexa what are the best places in the city";
        reprompt = "your reprompt";
     } else if ( //check for FoodIntent ) {

       // do accordingly
     }
     this.attributes['previousIntent'] = "Amazon.YesIntent";
     this.emit(":ask", speechOutput, reprompt);
  }

使用状态处理程序
ask nodejs sdkv1具有基于状态生成响应的状态处理程序。这个想法与此类似，sdk将为您添加sessionAttribute参数，而when将根据该状态自动映射处理程序。

 'InCityIntent': function () {
       const speechOutput = "The atmosphere in the city is beautiful. Is there anything else you would like to know";
       const reprompt = "Is there anything else you would like to know";
       this.handler.state = "ANYTHING_ELSE";
       this.emit(":ask", speechOutput, reprompt);
  }

const stateHandlers = Alexa.CreateStateHandler("ANYTHING_ELSE", {
    "AMAZON.YesIntent": function () {
       var speechOutput =  "You can learn more about city by trying, Alexa what are the best places in the city";
       var reprompt = "your reprompt";
       this.emit(":ask", speechOutput, reprompt);
    },

一旦设置了状态，那么下一次将触发该特定状态处理程序中定义的意图处理程序。相应地更改状态，完成后，将其删除。
