[自动化－脚本]002.cocos2dx-lua lua代码windows加密批处理

在开发软件的时候，我们都会在项目上线时候对代码进行加密，用来防止被不法分子盗走牟利。不同的语言有不同的加密方式，比较出名的有加壳，代码混淆等。在Lua开发cocos2dx的时候，框架会有提供加密的脚本。下面我说说加密windows的步骤

1.要知道要加密的源码的存放路径，并指定备份路径

2.把代码拷贝到备份路径

3.对所有的脚本进行去bom处理

4.用php命令compile_scripts.php进行加密处理。

根据以上的四点，我们下面贴出UTF8 去bom的代码和加密的整体代码

1.UTF-8

#! /usr/bin/python
# -*- coding: utf-8 -*-

import os
import sys
import codecs

def convert(dirname, filename):
	if os.path.splitext(filename)[1] in ['.txt', '.py,', '.lua', '.sh']:
		path = os.path.join(dirname, filename)
		print 'converting %s'%(path)
		f = open(path, 'rb')
		content = f.read(3)
		if content != '\xEF\xBB\xBF':
			print '%s is not utf-8 bom'%(path)
			return
		content = f.read()
		f.close()
		f = open(path, 'wb')
		f.write(content)
		f.close()
		print 'convert %s finish'%(path)

def useage():
	if len(sys.argv) == 1:
		print 'useage: utf8 file or dir...'
		return True

def exist_error(f):
	if not os.path.exists(f):
		print 'error: %s is not exist'%(f)
		return True

def main():

	if useage():
		return

	for f in sys.argv[1:]:
		if exist_error(f):
			break
		if os.path.isdir(f):
			for root, dirs, files in os.walk(f):
				for i in files:
					convert(root, i)
		else:
			convert('', f)

if __name__ == '__main__':
	main()

2.compile_scripts.php

1. Add code to AppDelegate.cpp:

3.加密脚本

@echo on
set _P_=bbframework
set _T_=script_bak

cd ..
mkdir %_T_%
mkdir %_T_%\scripts
mkdir %_P_%\updatescripts

echo "Copy Scripts to bak floder"
xcopy /E %_P_%\scripts %_T_%\scripts
cd %_P_%

echo "UTF-8 transition"
python ..\bin\utf8\main.py scripts

echo "Handle <<updatescripts>> Begin.."
move /Y scripts/app updatescripts/app
php ..\bin\__lib__\compile_scripts.php -zip -suffix "bin" updatescripts res\update

pause

以上就是windows上对lua代码进行加密的步骤
