我目前正在为我的智能家居开发Alexa技能。 我创建了一个Lambda函数，并希望向服务器发出http请求。但它不会执行我的任何一个。功能。
lambda代码示例：
/* This code has been generated from your interaction model by skillinator.io
/* eslint-disable func-names */
/* eslint quote-props: ["error", "consistent"]*/
// There are three sections, Text Strings, Skill Code, and Helper Function(s).
// You can copy and paste the contents as the code for a new Lambda function, using the alexa-skill-kit-sdk-factskill template.
// This code includes helper functions for compatibility with versions of the SDK prior to 1.0.9, which includes the dialog directives.
// 1. Text strings =====================================================================================================
// Modify these strings and messages to change the behavior of your Lambda function
const request = require("request");
let speechOutput;
let reprompt;
let welcomeOutput = "Hallo xyz!";
let welcomeReprompt = "xy";

我对http请求使用“请求”模块，我想大家都知道这个模块。
当我测试我的函数时，它没有运行时错误！ 但是MakeRequest调用和request.get调用中的匿名函数将不会执行，我也不知道为什么。 例如，控制台输出：
Hallo！，
Asd（非常有趣。它获取了request.get的参数。错误必须在调用中的第二个参数（anon函数本身？）和anon函数的开始之间），
hffggh，
asdww
-console.logs匿名输入。功能不显示。
我也许不理解为什么MakeRequest功能。不会运行->因为它的回调从未发生。但是为什么request.get不起作用？我在一个普通的节点项目中粘贴了必要的部分（MakeRequest和帮助器函数），并且有效！！ -facepalm ....我快哭了..
我的目标：我想从服务器接收响应。-就是这样。但这只是不会进入我可以访问响应对象的功能。

请帮帮我，我真的可以把头撞在墙上。
