快速使用json-server搭建静态api

什么是JSON Server

JSON Server是基于nodejs的静态API框架，能将本地静态文件快速映射成静态的REST API。

至于什么是REST API？请参考廖雪峰老师的网站上这篇解释，非常的通俗易懂。https://www.liaoxuefeng.com/wiki/1022910821149312/1105003357927328

快速上手

1. 安装json-server

   npm install -g json-server  #全局安装json-server

2. 新建一个db.json

   {
     "articles":[
         {
             "id":1,
             "title":"JSP JavaBean",
             "url":"https://www.runoob.com/jsp/jsp-javabean.html",
             "comments":[
                 {
                     "id":1,
                     "user":"Peter",
                     "context":"good article!"
                 },{
                     "id":2,
                     "user":"Tom",
                     "context":"nice points!"
                 }
             ]
         },
         {
             "id":2,
             "title":"what's REST API?",
             "url":"https://www.liaoxuefeng.com/wiki/1022910821149312/1105003357927328",
             "comments":[
                 {
                     "id":1,
                     "user":"Mary",
                     "context":"valuable article!"
                 },{
                     "id":2,
                     "user":"Jack",
                     "context":"not bad!"
                 }
             ]
         }
     ],
     "menu":[
         {
             "id":1,
             "menu_name":"MainPage"
         },{
             "id":2,
             "menu_name":"Java"
         }
     ]
   }

3. 启动json-server服务

   json-server --watch db.json
   //出现以下信息标识成功
   /**

   {^_^}/ hi!

   Loading db.json
   Done

   Resources
   http://localhost:3000/articles
   http://localhost:3000/menu

   Home
   http://localhost:3000

   Type s + enter at any time to create a snapshot of the database
