1、先用 npm init 创建一个package.json，然后添加依赖 node-static ，package.json 如下：

{
  "name": "freeswitch",
  "version": "1.0.0",
  "description": "test freeswitch for webrtc",
  "main": "server.js",
  "dependencies": {
    "node-static": "^0.7.9"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node server.js"
  },
  "keywords": [
    "webrtc"
  ],
  "author": "foruok",
  "license": "ISC"
}

2、执行npm install

3、创建 server.js 文件，内容如下：

var fs = require("fs");
var static = require('node-static');

var file = new static.Server('./public');

const options = {
  key: fs.readFileSync('./server.key'),
  cert: fs.readFileSync('./server.crt')
};

require('https').createServer(options, function (request, response) {
    request.addListener('end', function () {
        file.serve(request, response);
    }).resume();
}).listen(8000);

3、启动服务

<!DOCTYPE html>
<html>
  <head>
    <title>test</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="Author" content="foruok" />
    <meta name="description" content="JsSIP based example web application." />
    <style type="text/css">
    </style>
</head>
<body>hello world!</body>
</html>

新建public目录，并且随便在 public 目录下放个什么 html 文件，比如 test.html 。

用 npm start 启动服务，可以在 Chrome 浏览器内输入地址 https://127.0.0.1:8000/test.html测试一下。

如果能看到，说明服务正常。
