前言：
大家都知道,只要进行数据交互,肯定就要去请求接口,数据请求的方式有vue-resource axios fetch等方式进行数据集请求
JavaScript最新标准出的一个数据请求方式今天跟大家谈谈我们最熟悉,也是最常用的axios
安装：
npm install --save axios
最简单的写法
get请求：
axios.get("请求地址?kty=val&key=val").then(()=>{
//成功的回调函数
}).catch(()=>{
//失败的回调函数
})post请求
一般写法
axios.post("请求地址",{发送的key:发送的val,xxx:xxx}.then(()=>{
//请求成功的回调函数
}).catch(()=>{
//失败的回调函数
})
