axios POST提交數據的三種請求方式寫法

一、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);            
})

二、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);            
})

三、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);            
})

總結：
一、從jquery轉到axios最難忘的就是要設置Content-Type，還好如今都搞懂了他們的原理
二、上面三種方式會對應後臺的請求方式，這個也要注意，好比java的@RequestBody，HttpSevletRequest等等
