json server服务器

json文件可以理解为数据库

一、json-server快速搭建RESTAPI

安装：

sudo cnpm install -g json-server

启动（使用）：

json-server指向json文件所在位置

data.json文件：

json-server ./mock/data.json

API server启动在localhost:3000。支持GET，POST，PUT，PATCH，DELETE等REST命令。

每一个json数组对应一个表

资源以名词形式作为API路径。

二、测试REST API

浏览器测试get，但不能测试post，put, delete等。

几种常见的API测试工具

1、使用Postman测试常用API

下载：https://www.getpostman.com/

安装成功如下：

Get操作很简单，输入url，点Send即可。 

Post操作需要在header中指明参数。

• 指明Content-Type是application.json

• Body中给出一个json对象

服务器返回刚才创建的对象。

json server强大的地方是，可以不传id，会自动生成。因为真实开放中也是在服务器生成ID的。

 json文件中的数据也会被更新。 

2、使用VSCode的REST Client插件

创建一个后缀名是.http的文件rest.http

REST Client用纯文本描述请求，POST Man是有图形界面的。

发出一个post请求到 http://localhost:8090/auth，它的Content-Type是什么类型，然后携带的json是什么。

注意：

• 在json和http头部上面有一个空行
• 需要用###将不同的请求隔离开

// Login
POST http://localhost:8090/auth
Content-Type: application/json;charset: utf-8

{
    "username":"peng1",
    "password":"peng1234"
}
