下載：
npm install vue-router
路由的傳參：
1.查詢字符串：
/user/regist?uname=jack&upwd=123
接收：
{{$route.query}}
2.rest風(fēng)格傳參
/user/login/rose/456
路由的傳參：

axios是VUE中的AJAX
做的是前臺頁面與后臺數(shù)據(jù)之間的交互作用
用GIT獲取假服務(wù)器和端口號，實現(xiàn)交互

//2.創(chuàng)建組件
var Home={

`
}
var User={
template:`
<div>
<h1>這是用戶頁</h1>
<table border=1 cellspacing=0>
<thead>
<tr>
<th>編號</th>
<th>品名</th>
<th>單價</th>
<th>數(shù)量</th>
<th>小計</th>
</tr>
</thead>
<tbody>
<tr v-for="value in list">

<td>{{value.pname}}</td>
<td>{{value.price}}</td>
<td>{{value.count}}</td>
<td>{{value.sub}}</td>
</tr>

</table>
</div>
`,
data:function(){
return{
list:null
}
},
mounted:function(){
var self=this;
axios({
method:"get",//get post
url:'fruit.json'
}).then(function(resp){//請求成功
console.log(resp.data)
self.list=resp.data;
}).catch(function(err){//請求失敗
console.log(err)
})
}
}
//3.配置路由
const routes=[
{path:'/',component:Home},
{path:'/home',component:Home},
{path:'/user',component:User}
]
//4.創(chuàng)建路由實例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
//5.路由實例掛載到vue實例上
new Vue({
el:'#app',
router:router
})
</script>
</body>
</html>
就可以實現(xiàn)
