本文介绍了一种利用Python内置库gzip结合StringIO模块实现从内存中读取并解压zip文件的方法。通过将文件内容读入内存，使用StringIO创建一个类似文件的对象，并以此对象为基础创建gzip解压实例，最终将解压后的数据写入到新的文本文件中。

Decompress in memory data with gzip and StringIO.StringIO

import gzip
import StringIO

data = open('f.zip').read()
fobj = StringIO.StringIO(data)
fi = gzip.GzipFile(fileobj=fobj)
fw = open('decompress.txt', 'w')
fw.write(fi.read())
fw.close()

确定要放弃本次机会？

Assetbundle解密问题记录: Failed to decompress data for the Assetbundle

最近因为项目需求要研究assetbundle资源加密，踩了不少坑，记录一下。相信不少人和我一样一开始是去网上找看别人怎么做的，大家看的案例都差不多。但之前别人分享不知道是不是因为是很久之前的版本，只列了代码，没有说任何要注意的地方，难道之前的版本什么都不用注意就可以加密解密吗？现在的版本是不太行。。。不过加密一般没什么问题主要是解密的问题 #什么时候开始解压的这涉及到Failed to d...

这节主要讲unity资源优化，先学习一个概念吧：资源管道，原始文件通过内容管道变成了一个可被Unity高效使用的中间文件，这不是Unity里面的一个概念，但Unity的工作行为和它很类似；Unity在导入资源的时候可以使用类型丰富的文件，这不意味着在我们生成的App中同样也是这些文件，资源通过Unity的资源管道变成了较为统一的格式。我们在导入资源的时候有很多参数可以调整， 1 首先从

基于zigbee+wifi的井下监控系统设计和实现

05-18

针对目前井下监控系统采用单一协议兼顾不到合理利用网络资源、降低能耗、提高传输速率等问题,设计了一种基于zigbee+wifi混合型协议的无线传感器网络监控系统。该系统采用zigbee协议传输非视频数据,通过分簇式链状无线网络上传到地面监控中心;采用wifi协议上传音视频信息,两者的结合最大限度的降低了单一wifi协议所带来的高成本、高功耗以及单一zigbee协议传输音视频数据实时性差的问题。实际应用效果表明,该混合型协议无线网络监控系统大大提高了系统的可靠性和安全性。
