前端mock数据之mockjax和mockjson

用处

在前后台共同进行一个项目的时候常会遇到一种情景, 后台定义好接口,前端按照接口进行开发, 当前端开发完成后台接口却还没有开发完成, 这个时候要进行接口测试, 只能等后台开发完成才能测试, 在这中间浪费了很多时间, 现在有个利器可以解决这个问题, 即使不用后台,只要提前制定好接口的报文,那么前端就可以自己模拟接口来进行接口测试了, 今天要讲的东西就是mockjax和mockJSON

简介

mockjax和mockJSON是两套不同的Javascript Library, 它们都是基于JQuery来开发的,

mockjax主要是可以针对指定的网址进行mock, 当Ajax呼叫网址时拦截并回传假的数据,

mockJSON则有点像是Json资料的Data Generater, 根据我们指定的格式随机数生成回传的Json资料.
