Vue Axios异步通信

Axios 是一个开源的可以用在浏览器端和Node.js 的异步通信框架，它的主要作用就是实现AJAX异步通信。

npm install axios

引入Axios在线包

<script src="https://unpkg.com/axios/dist/axios.min.js"></script>

案例

1.创建本地json数据 data.json

{
  "name": "创客未来",
  "url": "https://www.baidu.com",
  "page": 1,
  "isNonProfit": true,
  "address": {
    "street": "hanguangmen",
    "city": "shanxixian",
    "country": "zhongguo"
  },
  "links": [
    {
      "name": "bilibili",
      "url": "https://www.baidu.com"
    },
    {
      "name": "bilibili",
      "url": "https://www.baidu.com"
    }
  ]
}

2.加载数据并渲染

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<div id="vue">
    <div>{{info.name}}</div>
    <div>{{info.address.street}}</div>
</div>
<!--引入vue.js 包-->
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>

    var vm=new Vue({
        el:"#vue",
        data(){
            return{
                //请求的返回参数格式，必须和json字符串一样
                info:{
                    name:null,
                    address:{
                        street:null,
                        city:null,
                        country:null
                    }
                }
            }
        },
        mounted(){//钩子函数，一般做Ajax请求 链式编程
            axios.get('data.json').then(response=>(this.info=response.data))
        }
    });

</script>
</body>
</html>
