参考博客：https://www.jianshu.com/p/cec263b6b9ac
官方文档：https://docs.cocos.com/creator/manual/zh/advanced-topics/hot-update.html
官方提供的那个21点热更新demo，在ios和andriod真机端都没有跑出来，黑屏，粉屏，无语。。。
只好按参考博客的作者新建项目直接开搞
用真机测试，Creator自带的模拟器，能更新资源，但是更新后加载不了资源，没法测试效果
测试下来安卓和iOS是可以共用一套代码一次更新构建，安卓或者iOS构建的新版本，两端都会提示更新，且能正常更新和进入
Creator版本：2.1.0
HotUpdate.js 使用的是官方demo 最新里的
UpdatePanel.js 使用的是官方demo 最新里的
资源也是借用官方demo里的，整的目录结构如下
因为没有其他更多依赖，代码也放一下
HotUpdate.js

这是一个用于生成 Manfiest 文件的 NodeJS 脚本
使用样例：node version_generator.js -v 2.2.0 -u http://192.168.1.103:8081/remote-assets/ -s build/jsb-link/ -d assets/
-v 2.2.0 版本号
-u http://192.168.1.103:8081/remote-assets/ 远程地址
-s build/jsb-link/ 源文件路径build/jsb-link/或build/jsb-default/
-d assets/ 生成后目标路径

启本地服务器：这里使用NodeJS
1. 新建一个文件夹nodejs
2. 在nodejs中新建hotUpdate文件夹
3. 把构建后的res和src复制到hotUpdate文件夹中
4. 在nodejs文件夹中新建一个app.js脚本
var express = require(‘express‘@H_301_48@); var path = require(‘path‘@H_301_48@); var app =@H_301_48@ express(); app.use(express.static(path.join(__dirname,‘hotUpdate‘@H_301_48@))); app.listen(8081); // 端口自己起一个不常用的，以免被占用
5. 命令行进入到nodejs文件夹下，执行node app.js命令，启动服务器，
6. 可以访问http://192.168.1.103:8081/remote-assets/project.manifest，如果成功访问则服务器启动成功。
注意：192.168.1.103:8081 根据自己的本机地址更改，可以命令行ifconfig查看，也可以在这里查看
整理操作流程：
1、选择ios或者android平台构建
2、构建完成后拷贝官方的version_generator.js到项目根目录下（和assets同级）（后者使用上面贴的version_generator.js代码）
3、命令行进到version_generator.js目录，执行node version_generator.js -v 1.0.0 -u http://192.168.1.103:8081/remote-assets/ -s build/jsb-link/ -d assets/
4、在项目assets目录下会生成两个文件：project.manifest 和 version.manifest
5、回到Creator把Canvas节点上的脚本ManifestUrl属性关联上生成的project.manifest文件
6、xcode打开项目，运行到ios设备上
7、接下来制作新版本（hotUpdate页面左上角按钮会跳helloworld页面，我们再helloworld页面做点改动）
8、helloworld页面改动后，重新构建（构建属性不要调整）
9、把构建好的（在build/jsb-link/下）res和src拷贝到 启服务器的路径下（nodejs/hotUpdate/remote-assets/）
10、再一次执行：命令行进到version_generator.js目录，执行node version_generator.js -v 1.0.1 -u http://192.168.1.103:8081/remote-assets/ -s build/jsb-link/ -d assets/
11、在项目assets目录下会生成两个文件：project.manifest 和 version.manifest
12、将这两个文件同样拷贝到 启服务器的路径下（nodejs/hotUpdate/remote-assets/），目前目录结构如下
13、开始测试热更新，ios设备启动进入原来运行的app，点击检测更新，正常会提示有版本可以更新，然后点击更新，就能更新了，然后点击左上角按钮进入helloworld，查看改成所做修改
这个过程中会遇到的坑：ip不对，端口被占用，官方demo运行不了，版本混乱。。。
