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></html>

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
