• Cocos Creator 热更新


    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

    var UpdatePanel = require('./UpdatePanel');
    
    // Custom manifest removed the following assets:
    // 1. res/raw-assets/2a/2a40e5e7-4c4a-4350-9e5d-76757755cdd2.png
    // 2. res/raw-assets/2d/2d86a854-63c4-4b90-8b88-a4328b8526c2.png
    // So when custom manifest used, you should be able to find them in downloaded remote assets

    提示:拖到update_panel节点上后,对应属性参考官方demo,下面截个图

    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   

    官方说明如下:(链接:version_generator.js 文件)   

    • -v 指定 Manifest 文件的主版本号。
    • -u 指定服务器远程包的地址,这个地址需要和最初发布版本中 Manifest 文件的远程包地址一致,否则无法检测到更新。
    • -s 本地原生打包版本的目录相对路径。
    • -d 保存 Manifest 文件的地址。

    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');
    var path = require('path');
    var app = express();
    app.use(express.static(path.join(__dirname, 'hotUpdate')));
    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。。。
