axios POST提交数据的三种请求方式写法

1、Content-Type: application/json      ==> @RequestBody

import axios from 'axios'
let data = {"code":"57893","name":"kelly"};
axios.post(`${this.$url}/test/testRequest`,data)
.then(res=>{
    console.log('res=>',res);            
})

2、Content-Type: application/x-www-form-urlencoded

import axios from 'axios'
import qs from 'Qs'
let data = {"code":"1234","name":"yyyy"};
axios.post(`${this.$url}/test/testRequest`,qs.stringify(data))
.then(res=>{
    console.log('res=>',res);            
})

3、Content-Type: multipart/form-data

import axios from 'axios'
let data = new FormData();
data.append('code','6352');
data.append('name','kelly');
axios.post(`${this.$url}/test/testRequest`,data)
.then(res=>{
    console.log('res=>',res);            
})
