Axios-入门

介绍

Axios对原生Ajax进行了封装，简化书写，快速开发

官网：Axios中文文档 | Axios中文网 (axios-http.cn)

入门

1引入Axios的js文件

 <script src="js/axios.js"></script>

2使用Axios发送请求，并获取响应结果

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTE-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=l.0">
    <title>Ajax</title>
    <script src="js/axios.js"></script>
</head>

<body>
    <input type="button" value="获取数据Get" onclick="get()">
    <input type="button" value="获取数据Post" onclick="post()">

</body>
<script>
    function get(){
         axios({ mehod:"get",
           url:"http://yapi.smart-xwork.cn/mock/169327/emp/list"
      }).then(result=>{
         console.log(result);
      })
    }
    function post(){
         axios({ mehod:"post",
          url:"http://yapi.smart-xwork.cn/mock/169327/emp/deleteById",
          data:"id=1;"
        }).then(result=>{
            console.log(result);
        })
    }
   
</script>

</html>

axios({....对象信息....mehod,url(data)}).then(result)=>{}

then后面接一个result的自定义函数

post有个而外的data

请求方式别名

改写

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTE-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=l.0">
    <title>Ajax</title>
    <script src="js/axios.js"></script>
</head>

<body>
    <input type="button" value="获取数据Get" onclick="get()">
    <input type="button" value="获取数据Post" onclick="post()">

</body>
<script>
    // function get(){
    //      axios({ mehod:"get",
    //        url:"http://yapi.smart-xwork.cn/mock/169327/emp/list"
    //   }).then(result=>{
    //      console.log(result);
    //   })
    // }

    axios.get("http://yapi.smart-xwork.cn/mock/169327/emp/list").then(result=>{console.log(result);})



    // function post(){
    //      axios({ mehod:"post",
    //       url:"http://yapi.smart-xwork.cn/mock/169327/emp/deleteById",
    //       data:"id=1;"
    //     }).then(result=>{
    //         console.log(result);
    //     })
    //}

    axios.post("http://yapi.smart-xwork.cn/mock/169327/emp/deleteById", "id=1").then(result=>{console.log(result);})


</script>

案例：网页加载完成，调用vue生命周期的mounted（）向服务器发送请求返回数据赋值遍历渲染表格
