Cosos2d热更新Md5文件生成

关于cocos2d使用AssertManager热更新md5文件的生成

引言

项目开发中难免使用到热更新，现在的cocos提供了AssertManager帮我我们快速的实现热更新功能，代码网上有很多，只要注册号各个状态的回调就能实现功能。但是不知道怎么生成自己的热更新版本文件的朋友还是有很多。所以这里提供一个模板供大家参考，我会说其实是为了拿分？因为是模板所以大家用的时候要根据自己的工程和需求进行修改。拿来主义很香但是自己还是要动动脑子的。

正文(上代码)

//使用python

    b = f.read()#get file content.
    if not b :
      return
    myhash = hashlib.md5()#create a md5 object  
    myhash.update(b)#encrypt the file
    f.close()
    return myhash.hexdigest()
#read version
