axios:vue中的ajax，
作用：前台页面与后台数据的交互作用
用GIT获取假服务器和端口号，实现交互。
例：
<div id="app">
<router-link to="/home">首页</router-link>
<router-link to='/user'>用户页</router-link>
<router-view></router-view>
</div>
<script src="js/vue.js"></script>
<script src="js/vue-router.js"></script>
<script src="js/axios.js"></script>
<script>
var Home={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<div>
<h1>这是登录页面</h1>
