1、自动更新js (AutoUpdate.js)
javascript
import { Modal } from "antd"
let lastSrcs;
const scriptReg = /\<script.*src=["'](?<src>[^"']+)/gm;
async function extractNewScripts() {
const html = await fetch('/?_timnestamp=' + Date.now()).then(res => {
return res.text();
})
scriptReg.lastIndex = 0;
let result = [];
let match;
console.log(html)
while ((match = scriptReg.exec(html))) {
result.push(match.groups.src)
}
return result;
}
async function needUpdate() {
const newScripts = await extractNewScripts();
if (!lastSrcs) {
lastSrcs = newScripts
return false;
}
let result = false;
if (lastSrcs.length !== newScripts.length) {
result = true;
}
for (let i = 0; i < lastSrcs.length; i++) {
if (lastSrcs[i] !== newScripts[i]) {
result = true;
break;
}
}
lastSrcs = newScripts;
return result
}
const duration = 5000;
function autoRefresh() {
setTimeout(async () => {
const willUpdate = await needUpdate();
if (willUpdate) {
Modal.success({
content: '当前系统有更新,请刷新',
keyboard: false,
onOk: () => {
location.reload(true);
}
});
}
autoRefresh();
}, duration)
};
autoRefresh();
2、修改webpack出口打包文件名称
3、引入AutoUpdate.js
javascript
import './util/AutoUpdate';
