使用json-Server与postman快速模拟服务环境搭建

2021-11-15 16:21:41

在前后端分离的这种工作模式下，分工明确，各司其职。前端负责展示数据，后端提供数据。然而，在这种过程中对于接口的规范需要提前制定好。例如根据规范提前模拟数据，这个时候就比较麻烦的。JsonServer这个比较NB了,它可以快速搭建服务端环境，创建json文件，便于调用。然后可以通过下载postman与json-server结合，可以实现数据的增删改查功能。下面是使用过程：

在浏览器中打开 http://jsonplaceholder.typicode.com/ 可以看到里面的一些数据

1.首先安装Node.js (https://nodejs.org/en/)

$ npm install -g json-server (全局安装json-server)

　　出现这样的情况，说明执行完成

2.进入你创建的目录里。cd json-server(json-server是我创建的文件名称)

npm init 初始化

This utility will walk you through creating a package.json file.

It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields

and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and

save it as a dependency in the package.json file.

Press ^C at any time to quit.

package name: (1)

version: (1.0.0)

description:

entry point: (index.js)

test command:

git repository:

keywords:

author:

license: (ISC)

About to write to G:\1\package.json:

{

  "name": "1",

  "version": "1.0.0",

  "description": "",

  "main": "index.js",

  "scripts": {

    "test": "echo \"Error: no test specified\" && exit 1"

  },

  "author": "",

  "license": "ISC"

}

Is this OK? (yes)
