没有时间加以说明，而且代码也还很粗糙，暂时先直接上代码，记录着，周末有空再升级代码并说明。

代码

let leAxios = {}
leAxios.httpRequest = function (paramObj, sucFun, errFun, complete) {var xmlhttp = null;/** 关于XMLHttpRequest https://www.w3school.com.cn/xml/xml_http.asp * 创建XMLHttpRequest对象，所有现代浏览器 (IE7+、Firefox、Chrome、Safari 以及 Opera) 都内建了 XMLHttpRequest 对象。* 老版本的 Internet Explorer（IE5 和 IE6）使用 ActiveX 对象：new ActiveXObject("Microsoft.XMLHTTP")* */if (window.XMLHttpRequest) {xmlhttp = new XMLHttpRequest();} else if (window.ActiveXObject) {//大可不必适配xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}/*判断是否支持请求*/if (xmlhttp == null) {alert('你的浏览器不支持XMLHttp');return;}/*请求方式，并且转换为大写*/var httpType = (paramObj.type || 'GET').toUpperCase();/*数据类型*/var dataType = paramObj.dataType || 'json';/*请求接口*/var httpUrl = paramObj.httpUrl || '';/*是否异步请求，默认异步*/var async = paramObj.async || true;/*请求接收*/xmlhttp.onreadystatechange = function () {if (xmlhttp.readyState == 4) {if (xmlhttp.status == 200) {console.log(xmlhttp)/*成功回调函数*/sucFun({code: xmlhttp.status,mes: 'Ok',data: xmlhttp.responseText,});} else {errFun;}if (complete) {complete}} else {/*暂不处理*/}}/*接口连接，先判断连接类型是post还是get*/if (httpType == 'GET') {let paramData = paramObj.data || [];let requestData = '';for (var name in paramData) {requestData += name + '=' + paramData[name] + '&';}requestData = requestData == '' ? '' : requestData.substring(0, requestData.length - 1);console.log(requestData)if (requestData != '') {httpUrl = httpUrl + '?' + requestData}xmlhttp.open("GET", httpUrl, async);xmlhttp.send(null);} else if (httpType == 'POST') {xmlhttp.open("POST", httpUrl, async);//发送合适的请求头信息if (dataType == 'json') {// application/json;charset=UTF-8xmlhttp.setRequestHeader("Content-type", "application/json;charset=UTF-8");} else {// application/x-www-form-urlencodedxmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");}xmlhttp.send(JSON.stringify(paramObj.data));}
}
export default leAxios

使用

<script>
import leAxios from './leAxois'expot defult {methods: {test() {let paramObj = {httpUrl: 'http://114.115.xxx.xxx:8080/invoice/user/login',type: 'post',data: {account: '177087788xx',password: '111111', }}/*请求调用*/leAxios.httpRequest(paramObj, function (respondDada) {//这里编写成功的回调函数console.log(respondDada)}, function () {alert('网络错误')});},}
}
</script>
