Python:监控键盘输入、鼠标操作，并将捕获到的信息记录到文件中
使用pyhook模块可以很快地完成键盘及鼠标事件捕获，此模块可从http://sourceforge.net/projects/pyhook/files/pyhook/1.5.1/下载，API手册：http://pyhook.sourceforge.net/doc_1.5.0/，网站上提供了个使用的例子，改写了下，将信息记录到文件中，本来想使用python的logging模块，但测试时发现，因为鼠标事件频率太高，导致写时报I/O错误的异常，所以使用了自己写文件记录日志的方式。代码：
#!/usr/bin/env python# -*- coding: utf-8 -*-import pythoncomimport pyHookimport timedef onMouseEvent(event):"处理鼠标事件"fobj.writelines('-' * 20 + 'MouseEvent Begin' + '-' * 20 + '\n')fobj.writelines("Current Time:%s\n" % time.strftime("%a, %d %b %Y %H:%M:%S", time.gmtime()))fobj.writelines("MessageName:%s\n" % str(event.MessageName))fobj.writelines("Message:%d\n" % event.Message)fobj.writelines("Time_sec:%d\n" % event.Time)fobj.writelines("Window:%s\n" % str(event.Window))fobj.writelines("WindowName:%s\n" % str(event.WindowName))fobj.writelines("Position:%s\n" % str(event.Position))fobj.writelines('-' * 20 + 'MouseEvent End' + '-' * 20 + '\n')return Truedef onKeyboardEvent(event): "处理键盘事件" fobj.writelines('-' * 20 + 'Keyboard Begin' + '-' * 20 + '\n')fobj.writelines("Current Time:%s\n" % time.strftime("%a, %d %b %Y %H:%M:%S", time.gmtime()))fobj.writelines("MessageName:%s\n" % str(event.MessageName))fobj.writelines("Message:%d\n" % event.Message)fobj.writelines("Time:%d\n" % event.Time)fobj.writelines("Window:%s\n" % str(event.Window))fobj.writelines("WindowName:%s\n" % str(event.WindowName))fobj.writelines("Ascii_code: %d\n" % event.Ascii)fobj.writelines("Ascii_char:%s\n" % chr(event.Ascii))fobj.writelines("Key:%s\n" % str(event.Key))fobj.writelines('-' * 20 + 'Keyboard End' + '-' * 20 + '\n')return Trueif __name__ == "__main__": '''Function:操作SQLITE3数据库函数Input：NONEOutput: NONEauthor: socratesblog:http://blog.csdn.net/dyx1024date:2012-03-1'''#打开日志文件file_name = "D:\\hook_log.txt"fobj = open(file_name,'w') #创建hook句柄hm = pyHook.HookManager()#监控键盘hm.KeyDown = onKeyboardEventhm.HookKeyboard()#监控鼠标hm.MouseAll = onMouseEventhm.HookMouse()#循环获取消息pythoncom.PumpMessages()#关闭日志文件fobj.close()

由上面的记录可以看出，当时我通过IE上淘宝，并且输入了google这个单词，有可能这是商品名，用户名，或者密码，呵呵。
查看Ascii_char字段即可看出输入的字母。如果没有解析出来，可通过Ascii_code字段的值到ASCII表中查找即可。
附：
ASCII（American Standard Code for Information Interchange，美国信息互换标准代码，ASCⅡ）是基于拉丁字母的一套电脑编码系统。它主要用于显示现代英语和其他西欧语言。它是现今最通用的单字节编码系统，并等同于国际标准ISO/IEC 646。
ASCII第一次以规范标准的型态发表是在1967年，最后一次更新则是在1986年，至今为止共定义了128个字符，其中33个字符无法显示（这是以现今操作系统为依归，但在DOS模式下可显示出一些诸如笑脸、扑克牌花式等8-bit符号），且这33个字符多数都已是陈废的控制字符，控制字符的用途主要是用来操控已经处理过的文字，在33个字符之外的是95个可显示的字符，包含用键盘敲下空白键所产生的空白字符也算1个可显示字符（显示为空白）。
