我正在为新的 Amazon ECHO 开发“技能”。该技能将允许用户向 Alexa 询问有关 Enphase 太阳系状态和性能的信息。Alexa 将以从基于 JSON 的 Enphase API 中提取的结果进行响应。例如,用户可能会问,
"Alexa. Ask Enphase how much solar energy I have produced in the last week."
ALEXA <"Your array has produced 152kWh in the last week.">
问题是我用 JavaScript 编程已经有好几年了,这是我第一次使用 AWS Lambda。我没有很成功地找到任何关于如何在 AWS Lambda 函数中将 JSON 查询嵌入到第三方服务器的信息。这是我的 Lambda 函数中的相关代码部分:
/**
* Gets power from Enphase API and prepares speach
*/
function GetPowerFromEnphase(intent, session, callback) {
var Power = 0;
var repromptText = null;
var sessionAttributes = {};
var shouldEndSession = false;
var speechOutput = "";

speechOutput = "Your array is producing " + Power + " kW, goodbye";
shouldEndSession = true;
// Setting repromptText to null signifies that we do not want to reprompt the user.
// If the user does not respond or says something that is not understood, the session
// will end.
callback(sessionAttributes,
buildSpeechletResponse(intent.name, speechOutput, repromptText,
shouldEndSession));
}
一些指导将不胜感激。即使有人能指出我正确的方向。谢谢!
