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

    1 {
    2   "articles":[
    3       {
    4           "id":1,
    5           "title":"JSP JavaBean",
    6           "url":"https://www.runoob.com/jsp/jsp-javabean.html",
    7           "comments":[
    8               {
    9                   "id":1,
   10                   "user":"Peter",
   11                   "context":"good article!"
   12               },{
   13                   "id":2,
   14                   "user":"Tom",
   15                   "context":"nice points!"
   16               }
   17           ]
   18       },
   19       {
   20           "id":2,
   21           "title":"what's REST API?",
   22           "url":"https://www.liaoxuefeng.com/wiki/1022910821149312/1105003357927328",
   23           "comments":[
   24               {
   25                   "id":1,
   26                   "user":"Mary",
   27                   "context":"valuable article!"
   28               },{
   29                   "id":2,
   30                   "user":"Jack",
   31                   "context":"not bad!"
   32               }
   33           ]
   34       }
   35   ],
   36   "menu":[
   37       {
   38           "id":1,
   39           "menu_name":"MainPage"
   40       },{
   41           "id":2,
   42           "menu_name":"Java"
   43       }
   44   ]
   45 }

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
