使用示例：

【旧】

import Axios from 'axios'

function crestUrl(str) {  // 拼接地址
	let url = 'http://' + localStorage.ipAddress + ':' + localStorage.port + BASE_URL + str
	return url 
}
function login(data) {
	let url = creatUrl('permit/token)
	return Axios({
		headers: { 'Content-Type': 'application/json;charset=UTF-8' },
		method: 'post',
		url: url,
		data: data
	})
}

【新】

function login(data) {
	let url = creatUrl('permit/token)
	return Axios.post(url, data) // 一行代码搞定！！
}

三种方法(还没验证暂时摆在这里回头看）

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);            
})
