cocos creator破解

经常用creator开发，但是有时候碰到一些问题，想看下creator源码，无赖creator不开源。 话不多说直接开始。

首先安装工具：

npm install --engine-strict asar -g

查看帮助：

➜  Resources asar --help
Usage: asar [options] [command]

Manipulate asar archive files

Options:
  -V, --version                         output the version number
  -h, --help                            display help for command

Commands:
  pack|p [options] <dir> <output>       create asar archive
  list|l [options] <archive>            list files of asar archive
  extract-file|ef <archive> <filename>  extract one file from archive
  extract|e <archive> <dest>            extract archive
  *
  help [command]                        display help for command

和zip命令类似， 先查看list命令。

➜  Resources asar help list
Usage: asar list|l [options] <archive>

list files of asar archive

Options:
  -i, --is-pack  each file in the asar is pack or unpack
  -h, --help     display help for command

直接进入creator安装目录

开始使用工具查看文件：

➜  Resources asar list -i app.asar
node:internal/buffer:84
    throw new ERR_BUFFER_OUT_OF_BOUNDS();
    ^

RangeError [ERR_BUFFER_OUT_OF_BOUNDS]: Attempt to access memory outside buffer bounds
    at new NodeError (node:internal/errors:370:5)
    at boundsError (node:internal/buffer:84:11)
    at Buffer.readUInt32LE (node:internal/buffer:220:5)

    at new PickleIterator (/usr/local/lib/node_modules/asar/node_modules/chromium-pickle-js/lib/pickle.js:27:28)
    at Pickle.createIterator (/usr/local/lib/node_modules/asar/node_modules/chromium-pickle-js/lib/pickle.js:144:12)
    at Object.module.exports.readArchiveHeaderSync (/usr/local/lib/node_modules/asar/lib/disk.js:78:31)
    at Object.module.exports.readFilesystemSync (/usr/local/lib/node_modules/asar/lib/disk.js:84:25)

    at Command.<anonymous> (/usr/local/lib/node_modules/asar/bin/asar.js:54:22) {
  code: 'ERR_BUFFER_OUT_OF_BOUNDS'
}

非常尴尬，越界了。可能app.asar 文件太大导致吧。现在开始对asar 工具动刀。

 从逻辑来看可能是sizeBuf太大。 加个日志打印一下下。。。

 

 看到这个信息，我就确定creator对 .asar做了特殊处理了。 900的大小，居然报错？

有时间再破解它，有加密就有解密。
