Alexa API通过lambda函数请求

我正在创建Alexa技能，并通过AWS Lambda托管了我的NodeJS代码。

我需要从API访问数据，并将其提取到我的Lambda函数中，以服务于Alexa。我如何使用Express或jQuery这样的包来允许通过我的Lambda函数进行API请求？

我发现了安装npm包的详细/复杂的方法，但我正在寻找是否有更好/不同的方法来完成

我使用了nodeJS http请求。包括getWelcomeResponse()中的这个请求和Alexa Dev中的测试，我得到了

无法调用远程终结点，或者它返回的响应无效。

如果没有HTTP请求，它将返回预期的json响应

 function getWelcomeResponse(callback) {
    console.log('GET WELCOME RESPONSE');
    var options = {
        host: 'http://clg-api-dev.elasticbeanstalk.com',
        port: 7474,
        path: '/1.0/leveldata/3',
        method: 'GET',
        headers: {
            accept: 'application/json'
        }
    };
    var x = http.request(options,function(res){
        console.log("Connected");
        res.on('data',function(data){
            console.log('My Data: ', data);
            var sessionAttributes = {},
            speechOutput = "Reindeer Games. I will ask you " + GAME_LENGTH.toString()
                + " questions, try to get as many right as you can. Just say the number of the answer. Let's begin. ",
            shouldEndSession = false,
            gameQuestions = populateGameQuestions(),
            sessionAttributes = {
                "speechOutput": repromptText,
                "repromptText": repromptText,
                "currentQuestionIndex": currentQuestionIndex,
                "correctAnswerIndex": correctAnswerIndex + 1,
                "questions": gameQuestions,
                "score": 0,
                "correctAnswerText":
                    questions[gameQuestions[currentQuestionIndex]][Object.keys(questions[gameQuestions[currentQuestionIndex]])[0]][0]
            };
            callback(sessionAttributes, buildSpeechletResponse(CARD_TITLE, speechOutput, repromptText, shouldEndSession));
        });
    });
    x.end();
}

其中错误为getaddrinfo ENOTFOUND at errnoException (dns.js:37:11) at Object.onanswer。我不太理解这个错误。
