什么是Mock.js

前后端分离开发开发过程当中，经常会遇到以下几个尴尬的场景：

- 老大，接口文档还没输出，我的好多活干不下去啊！

- 后端小哥，接口写好了没，我要测试啊！

前后端分离之后，前端迫切需要一种机制，不再需要依赖后端接口开发，而今天的主角mockjs就可以做到这一点。

Mock.js是一个模拟数据的生成器，用来帮助前端调试开发、进行前后端的原型分离以及用来提高自动化测试效率。

众所周知Mock.js因为两个重要的特性风靡前端:

数据类型丰富：支持生成随机的文本、数字、布尔值、日期、邮箱、链接、图片、颜色等。
拦截Ajax请求：不需要修改既有代码，就可以拦截Ajax请求，返回模拟的响应数据。

安装mockjs：

配置mockjs
