小程序启动下载逻辑相关：
https://game.weixin.qq.com/cgi-bin/h5/static/commlib/index.html
这个是实时的。 但是貌似本地也会存储，存储路径： /var/mobile/Containers/Data/Application/B1E7B553-B1EC-4679-A4C1-ED81541F0D44/Library/WechatPrivate/WePkg/Data/commlib/9192/pkg.dat
这个dat格式和wxapkg格式有一点差别， 暂时还没有找到怎么解压它的方法。
下载小程序相关逻辑：
function (e, t, n) { var i = n(4), o = n(0); (i.downloadAppInternal = i.downloadAppInternal || function (e, t) { e = e || {}; var n = o.clientVersion(!0); o.versionCompare(n, "6.5.6") >= 0 ? i.invoke("downloadAppInternal", e, t) : (t && t.call(i, {}), (window.location.href = e.appUrl)); }), (e.exports = i); }
downloadApp: {
ios: function (e) {
var t = e.appitem,
n = e.callback,
i = e.config || {};
T.detail.launchApp({
appitem: t,

e.err_msg.indexOf(":ok") > -1 || e.err_msg.indexOf(":yes") > -1

function (e) {

}
i.showDownloadConfirmAlert && o.isAndroid

launchAppOrH5: function (e) {
var t = e.appitem,
n = e.callback,
i = e.config || {},
o = T.detail;
o.launchApp({
appitem: t,

});
},
这些都是比较核心的逻辑。
appitem是很关键的数据结构， 小程序的下载地址为： appitem.DownloadInfo.DownloadURL
微信小程序和微信APP的交互，全靠window.WeixinJSBridge 这个是很关键的东西。
