axios POST提交数据的三种请求方式写法

1、Content-Type: application/json

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

2、Content-Type: multipart/form-data

import axios from 'axios'
let data = new FormData();
data.append('code','1234');
data.append('name','yyyy');
axios.post(`${this.$url}/test/testRequest`,data)
.then(res=>{
    console.log('res=>',res);            
})

3、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);            
})

总结：
1、从jquery转到axios最难忘的就是要设置Content-Type，还好现在都搞懂了他们的原理
2、上面三种方式会对应后台的请求方式，这个也要注意，比如java的@RequestBody，HttpSevletRequest等等
