uniapp 使用wgt包实现热更新具体实现代码

参考文档：https://ask.dcloud.net.cn/article/35667

app.vue

在onLaunch生命周期里面调用

import { GetRefres } from '@/utils/hot-refresh';
onLaunch(() => {// #ifdef APP-PLUSGetRefres();// #endif
});

utils/hot-refresh.js

//热更新
import home from '@/api/home';
export function GetRefres() {plus.runtime.getProperty(plus.runtime.appid as string, function (widgetInfo: any) {//获取版本 // 这里替换自己的接口home.GetWgt_API().then(res => {if (res.code == 200) {const { data } = res;const isBuld = versionAnswer(data.version, widgetInfo.version);//新，旧版本对比//如果高于后端的版本就执行热更新if (isBuld) {uni.downloadFile({url: data.url,success: (downloadResult) => {if (downloadResult.statusCode === 200) {plus.runtime.install(downloadResult.tempFilePath,{force: false},function () {console.log('install success...');plus.runtime.restart();},function () {console.error('install fail...');});}}});}}});});
}
function versionAnswer(vNew: string, vOld: string) {//返回的新版本判断是否有值if (vNew === '' || vNew === null || vNew === undefined) {return false;}const rel = /(^\s+)|(\s+$)/gi;let vn = vNew.replace(rel, '');let vo = vOld.replace(rel, '');const reg = /\d(\.|\d)*\d/gi;vn = vn.match(reg)[0];vo = vo.match(reg)[0];const vnArr = vn.split('.');const voArr = vo.split('.');// 版本比较 1.1.1类型if (+vnArr[0] > +voArr[0]) {return true;} else if (+vnArr[0] == +voArr[0]) {if (+vnArr[1] > +voArr[1]) {return true;} else if (+vnArr[1] == +voArr[1]) {if (+vnArr[2] > +voArr[2]) {return true;} else if (+vnArr[2] == +voArr[2]) {return false;}}}return false;
}
