如何获取并使用Alexa技能意图响应的确认'是'或'否'

Question

我正在开发一种Alexa技能,在启动它会询问,具体Do you want to perform something ?
取决于用户的回复'yes'或'no'我想发布另一个意图.

var handlers = {
  'LaunchRequest': function () {
    let prompt = this.t("ASK_FOR_SOMETHING");
    let reprompt = this.t("LAUNCH_REPROMPT");
    this.response.speak(this.t("WELCOME_MSG") + ' ' + prompt).listen(reprompt);
    this.emit(':responseReady');
  },
  "SomethingIntent": function () {
    //Launch this intent if the user's response is 'yes'
  }
};

我确实看过,dialog model似乎它将达到目的.但我不知道如何实现它.

做你从技能找什么最简单的方法,是处理AMAZON.YesIntent和AMAZON.NoIntent从你的技能(请务必将其添加到交互模型以及):

var handlers = {
  'LaunchRequest': function () {
    let prompt = this.t("ASK_FOR_SOMETHING");
    let reprompt = this.t("LAUNCH_REPROMPT");
    this.response.speak(this.t("WELCOME_MSG") + ' ' + prompt).listen(reprompt);
    this.emit(':responseReady');
  },
  "AMAZON.YesIntent": function () { 
    // raise the `SomethingIntent` event, to pass control to the "SomethingIntent" handler below 
    this.emit('SomethingIntent');
  },
  "AMAZON.NoIntent": function () {
    // handle the case when user says No
    this.emit(':responseReady');
  }
  "SomethingIntent": function () {
    // handle the "Something" intent here
  }
};

请注意,在更复杂的技能中,您可能需要存储一些状态,以确定用户发送了"是"意图以回答您是否"做某事"的问题.您可以使用会话对象中的技能会话属性来保存此状态.例如:

var handlers = {
  'LaunchRequest': function () {
    let prompt = this.t("ASK_FOR_SOMETHING");
    let reprompt = this.t("LAUNCH_REPROMPT");
    this.response.speak(this.t("WELCOME_MSG") + ' ' + prompt).listen(reprompt);
    this.attributes.PromptForSomething = true;
    this.emit(':responseReady');
  },
  "AMAZON.YesIntent": function () { 
    if (this.attributes.PromptForSomething === true) {
      // raise the `SomethingIntent` event, to pass control to the "SomethingIntent" handler below 
      this.emit('SomethingIntent');
    } else {
      // user replied Yes in another context.. handle it some other way
      //  .. TODO ..
      this.emit(':responseReady');
    }
  },
  "AMAZON.NoIntent": function () {
    // handle the case when user says No
    this.emit(':responseReady');
  }
  "SomethingIntent": function () {
    // handle the "Something" intent here
    //  .. TODO ..
  }
};

最后,您还可以在问题中提到使用Dialog接口,但是如果你要做的就是从启动请求中得到一个简单的Yes/No确认作为提示而不是我认为上面的示例将是非常直接地实施.
