Alexa 技能：播放音频结果 "Sorry don't know that"

Question

我正在编写我的第一个 alexa 技能，我非常兴奋！我正在尝试制作一项技能，以便当我说 "ramranch" 时，alexa 将播放 Sunil Syal。我使用 space 事实选择器蓝图开始这项技能。我已经删除了该代码并放入了我自己的代码。 aws 已连接并且正在工作，但是当我在测试控制台中说 "ramranch" 时，Alexa 以 "Sorry, I don't know that" 响应。他们没有调试或错误消息。

/* eslint-disable  func-names */
/* eslint-disable  no-console */

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

const RamRanch = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'LaunchRequest'
    || (request.type === 'IntentRequest'
      && request.intent.name === 'handle');
  },
  handle(handlerInput) {
    this.emit(':tell', "Let's enjoy a world's most beautiful composition, composed by the great, Sunil Syal, <audio src='https://my-apis.000webhostapp.com/audio/Romantic%20Solitude-Instrumental%20(Flute).mp3'/> Wow, That is amazing. Click the link on top right corner to listen to full song.");
  }
}
const HelpHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && request.intent.name === 'AMAZON.HelpIntent';
  },
  handle(handlerInput) {
    return handlerInput.responseBuilder
      .speak(HELP_MESSAGE)
      .reprompt(HELP_REPROMPT)
      .getResponse();
  },
};

const ExitHandler = {
  canHandle(handlerInput) {
    const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && (request.intent.name === 'AMAZON.CancelIntent'
        || request.intent.name === 'AMAZON.StopIntent');

很有可能你在修改蓝图技能时删除了节点模块。这是您的 index.js 代码的略微修改版本。开始一个节点项目 npm init。接下来 npm 安装 ask-sdk。您的项目文件夹现在将包含 node_modules、package-lock.json 和 package.json 添加此 index.js 文件。

const Alexa = require('ask-sdk-core');

const LaunchRequestHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'LaunchRequest';
  },
  handle(handlerInput) {
    const speechText = 'Welcome to the Alexa Skills Kit, you can say what about ramranch';

    return handlerInput.responseBuilder
      .speak(speechText)
      .reprompt(speechText)
      .withSimpleCard('Ramranch', speechText)
      .getResponse();
  }
};
const RamranchIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && handlerInput.requestEnvelope.request.intent.name === 'ramranchIntent';
  },
  handle(handlerInput) {
    const speechText = 'Lets enjoy a worlds most beautiful composition, composed by the great, Sunil Syal, <audio src="https://my-apis.000webhostapp.com/audio/Romantic%20Solitude-Instrumental%20(Flute).mp3"/> Wow, That is amazing. Click the link on top right corner to listen to full song.';

    return handlerInput.responseBuilder
      .speak(speechText)
      .withSimpleCard('Ramranch', speechText)
      .getResponse();

  }
};
const HelpIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && handlerInput.requestEnvelope.request.intent.name === 'AMAZON.HelpIntent';
  },
  handle(handlerInput) {
    const speechText = 'You can say what about Ramranch!';

    return handlerInput.responseBuilder
      .speak(speechText)
      .reprompt(speechText)
      .withSimpleCard('Ramranch', speechText)
      .getResponse();
  }
};
const CancelAndStopIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && (handlerInput.requestEnvelope.request.intent.name === 'AMAZON.CancelIntent'
        || handlerInput.requestEnvelope.request.intent.name === 'AMAZON.StopIntent');
  },
  handle(handlerInput) {
    const speechText = 'Goodbye!';

    return handlerInput.responseBuilder
      .speak(speechText)
      .withSimpleCard('Ramranch', speechText)
      .getResponse();
  }
};
const SessionEndedRequestHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'SessionEndedRequest';
  },
  handle(handlerInput) {
    //any cleanup logic goes here
    return handlerInput.responseBuilder.getResponse();
  }
};
const ErrorHandler = {
  canHandle() {
    return true;
  },
  handle(handlerInput, error) {
    console.log(`Error handled: ${error.message}`);

    return handlerInput.responseBuilder
      .speak('Sorry, I can\'t understand the command. Please say again.')
      .reprompt('Sorry, I can\'t understand the command. Please say again.')
      .getResponse();
  },
};

exports.handler = Alexa.SkillBuilders.custom()
  .addRequestHandlers(
    LaunchRequestHandler,
    RamranchIntentHandler,
    HelpIntentHandler,
    CancelAndStopIntentHandler,
    SessionEndedRequestHandler)
  .addErrorHandlers(ErrorHandler)
  .lambda();

请务必修改您的 Alexa 技能开发人员模型以包含 ramranchIntent，因为我没有像您的代码那样组合启动和主要意图。最后，将它与前面提到的其他文件一起压缩到 AWS 中的 lambda 函数中，并添加一些用于触发 Ramranch 的意图短语，在我的测试中我使用了这个技能 JSON
