App.vue 直接上代码

<script>export default {methods: {//APP 版本升级Urlupload() {// #ifdef APP-PLUSplus.runtime.getProperty(plus.runtime.appid, (info) => {// 版本号变量持久化存储getApp().globalData.version = info.version;this.ToLoadUpdate(info.versionCode, );})//#endif},//下载更新ToLoadUpdate(version, ) {uni.showModal({title: `版本更新 ${version}—>${171}`,content: "有更新版本啦!!!",confirmText: '立即更新',cancelText: '稍后更新',showCancel: true,success: (res) => {if (res.confirm) {if (plus.networkinfo.getCurrentType() != 3) { //获取手机设备的相关信息，判断是否在Wifi状态。uni.showToast({title: '检测到您目前非Wifi连接，为节约您的流量，建议您连接WIFI更新!',icon: 'none',duration: 5000});} else {uni.showToast({title: '程序已启动更新，请耐心等待!',icon: 'none',duration: 3000});}//设置 最新版本apk的下载链接const downloadApkUrl ='https://wfgtest-1631.oss.wefanbot.com/DEV/qw/106658768610001/1727229160089/wczd_v1.0.0.apk'console.log("downloadApkUrl===", downloadApkUrl);var dtask = plus.downloader.createDownload(downloadApkUrl, {}, (d, status) => { //新建下载任务if (status == 200) { //当下载完成uni.showModal({title: '下载成功',content: '确定现在安装吗？',confirmText: '立即安装',confirmColor: '#EE8F57',success: (res2) => {if (res2.confirm == true) {plus.runtime.install(plus.io.convertLocalFileSystemURL(d.filename), {}, {},(error) => { //安装应用uni.showToast({title: '安装失败',icon: 'none'});})}}})} else {uni.showToast({title: '更新失败',icon: 'none'});}})dtask.start();var prg = 0;var showLoading = plus.nativeUI.showWaiting("正在下载");dtask.addEventListener('statechanged', (task,status) => { //添加下载任务事件监听器// 给下载任务设置一个监听 并根据状态 做操作switch (task.state) {case 1:showLoading.setTitle("开始下载");break;case 2:showLoading.setTitle("已连接到服务器");break;case 3:prg = parseInt( //下载的进度(parseFloat(task.downloadedSize) /parseFloat(task.totalSize)) *100);showLoading.setTitle("版本更新,正在下载" + prg +"% ");if (prg === 100) {plus.nativeUI.closeWaiting(); //关闭系统提示框}break;case 4:plus.nativeUI.closeWaiting(); //关闭系统提示框//下载完成break;}});} else if (res.cancel) {}}});},},onLaunch() {this.Urlupload()},}
