dcloud资源升级方式更新app

时间:2022-05-12 03:51:24
var wgtVer = null;
plus.runtime.getProperty(plus.runtime.appid, function(inf) {
wgtVer = inf.version;
console.log("当前应用版本:" + wgtVer); // 检测更新
var checkUrl = getAbsUrl("update/check"); function checkUpdate() {
plus.nativeUI.showWaiting("检测更新...");
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
switch(xhr.readyState) {
case 4:
plus.nativeUI.closeWaiting();
if(xhr.status == 200) {
console.log("检测更新成功:" + xhr.responseText);
var newVer = xhr.responseText;
if(wgtVer && newVer && (wgtVer != newVer)) {
// 下载升级包
newVer = newVer.replace('.', '');
var wgtUrl = getAbsUrl("qr/" + newVer + ".wgt"); plus.nativeUI.showWaiting("下载wgt文件...");
plus.downloader.createDownload(wgtUrl, {
filename: "_doc/update/"
}, function(d, status) {
if(status == 200) {
console.log("下载wgt成功:" + d.filename);
// 安装wgt包
var path = d.filename;
plus.nativeUI.showWaiting("安装wgt文件...");
plus.runtime.install(path, {}, function() {
plus.nativeUI.closeWaiting();
console.log("安装wgt文件成功!");
plus.nativeUI.alert("应用资源更新完成!", function() {
plus.runtime.restart();
});
}, function(e) {
plus.nativeUI.closeWaiting();
console.log("安装wgt文件失败[" + e.code + "]:" + e.message);
plus.nativeUI.alert("安装wgt文件失败[" + e.code + "]:" + e.message);
});
}
plus.nativeUI.closeWaiting();
}).start();
}
} else {
console.log("检测更新失败!");
}
break;
default:
break;
}
}
xhr.open('POST', checkUrl);
xhr.send();
} checkUpdate();
});
 

下面是整包更新的代码:

mui.getJSON(getAbsUrl('update/check'), {
"appid": plus.runtime.appid,
"version": plus.runtime.version
}, function(data) {
if(data.status) {
plus.nativeUI.confirm(data.note, function(event) {
if(0 == event.index) {
plus.runtime.openURL(data.url);
}
}, data.title, ["立即更新", "取  消"]);
}
});
