如何获取和使用 Alexa 技能意图响应的确认“是”或“否”

我正在开发一项 Alexa 技能，在启动时它会询问Do you want to perform something ?
取决于用户的回复'yes' or 'no'我想发起另一个意图。

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看来它会达到目的。但我不确定如何实施。

实现您从技能中寻找的目标的最简单方法是处理AMAZON.YesIntent and AMAZON.NoIntent根据您的技能（确保将它们也添加到交互模型中）：

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，您可能必须存储一些状态才能确定用户发送了“是”意图来响应您是否“做某事”的问题。您可以使用技能会话属性来保存此状态会话对象 https://developer.amazon.com/docs/custom-skills/request-and-response-json-reference.html#session-object。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，您还可以考虑使用对话界面 https://developer.amazon.com/docs/custom-skills/dialog-interface-reference.html正如您在问题中提到的，但如果您想做的只是从启动请求中获得一个简单的是/否确认作为提示，那么我认为上面的示例将非常容易实现。
