## 1.1 什么是Swagger ##

随着互联网技术的发展，现在的网站架构基本都由原来的后端渲染，变成了：前端渲染、先后端分离的形态，而且前端技术和后端技术在各自的道路上越走越远。  
前端和后端的唯一联系，变成了API接口；API文档变成了前后端开发人员联系的纽带，变得越来越重要， swagger 就是一款让你更好的书写API文档的框架。

## 1.2 SwaggerEditor安装与启动 ##

1）全局安装http-server  
http-server是一个简单的零配置命令行http服务器  
npm install ‐g http‐server  
2）启动swagger-editor  
cmd进入swagger-editor所在文件夹  
http‐server swagger‐editor  
浏览器打开： http://localhost:8080

## 1.4 SwaggerUI环境搭建 ##

1.新建works文件夹，然后进入到 works目录，执行初始化命令：npm init ，出现如下信息，填的地方可以随便写，也可以不写  
2. 解压swagger-ui-master.zip,将dist 文件夹复制到 works下  
3. 安装express cd works>npm install express  
4. 在works文件夹下创建index.js

var express = require('express');
    var app = express();
    app.use('/root', express.static('dist'));
    app.get('/', function (req, res) {
      res.send('Hello World!');
    });
    app.listen(3000, function () {
      console.log('Example app listening on port 3000!');
    });

5.然后启动，并运行查看，如上代码为3000端口，如有冲突请自行修改

cd works>node index.js // 启动命令  
Example app listening on port 3000!

浏览器输入地址：http://127.0.0.1:3000/root/index.html  
6.使用自己的api文档  
works/dist/index.html下 修改
