如何让Swagger监听服务器IP地址而不是本地主机

Question

我已通过以下步骤在Ubuntu 16.04操作系统上安装了Swagger Editor：

1. sudo apt-get install nodejs-legacy
2. git clone https://github.com/swagger-api/swagger-editor.git
3. sudo apt-get install npm
4. cd swagger-editor
5. npm start
6. I edited the APIs I wanted using Swagger Editor
7. I generated a NodeJS Server from Swagger Editor Menu
8. I extracted my server zip file and CD into it.
9. npm install connect
10. npm install swagger-tools
11. npm install js-yaml 
12. node index.js             <-- START MY SERVER

结果是：

me@ubuntu:~/Downloads/nodejs-server-server$ node index.js
Your server is listening on port 8081 (http://localhost:8081)
Swagger-ui is available on http://localhost:8081/docs

问题： 您在这里看到它仅在 localhost 上监听。

如何使服务器侦听服务器的实际IP地址而不是本地主机的IP地址？我想从另一台PC访问它吗？

这是Swagger生成的默认 index.js 文件：

'use strict';

var fs = require('fs'),
    path = require('path'),
    http = require('http');

var app = require('connect')();
var swaggerTools = require('swagger-tools');
var jsyaml = require('js-yaml');
var serverPort = 8080;

// swaggerRouter configuration
var options = {
  swaggerUi: path.join(__dirname, '/swagger.json'),
  controllers: path.join(__dirname, './controllers'),
  useStubs: process.env.NODE_ENV === 'development' // Conditionally turn on stubs (mock mode)
};

// The Swagger document (require it, build it programmatically, fetch it from a URL, ...)
var spec = fs.readFileSync(path.join(__dirname,'api/swagger.yaml'), 'utf8');
var swaggerDoc = jsyaml.safeLoad(spec);

// Initialize the Swagger middleware
swaggerTools.initializeMiddleware(swaggerDoc, function (middleware) {

  // Interpret Swagger resources and attach metadata to request - must be first in swagger-tools middleware chain
  app.use(middleware.swaggerMetadata());

  // Validate Swagger requests
  app.use(middleware.swaggerValidator());

  // Route validated requests to appropriate controller
  app.use(middleware.swaggerRouter(options));

  // Serve the Swagger documents and Swagger UI
  app.use(middleware.swaggerUi());

  // Start the server
  http.createServer(app).listen(serverPort, function ()
  {
    console.log('Your server is listening on port %d (http://localhost:%d)', serverPort, serverPort);
    console.log('Swagger-ui is available on http://localhost:%d/docs', serverPort);
  });  

});
