axios
下载：npm install axios
版本
1.0：vue-resource
2.0：axios（相当于库）
Vue中的ajax
ajax作用：前端页面和后台数据做交互
在写是需要有一个.json的文档
axios({
method:'get'//get post,
url:'路径'
}).then(function(rext){//请求成功
console.log(rext.data)
}).catch(function(tex){//请求失败
console.log(tex)
})
在执行时，需要安装http-server
安装指令：npm install http-server -g
开启一个服务：http-server
