晚上學習了下python定義系統級快捷鍵的方法，這里說的系統級快捷鍵指的是,如果當前程序窗口不為激活窗口，也能收到快捷鍵消息，實現的是一個控制鍵盤和鼠標監聽的程序，如，按下Ctrl + F3,程序開始記錄監控日志。本來想實現按下Ctrl + F4程序程序停止記錄日志，但測試時遇到了一個沒有目前還沒有想到解決辦法的問題，先看實現。 ### 一、代碼： ~~~ #!/usr/bin/env python # -*- coding: utf-8 -*- import pythoncom import pyHook import time import pyhk import os import sys import ctypes from ctypes import wintypes import win32con class CInspectKeyAndMouseEvent: ''' Function:鍵盤和鼠標監控類 Input：NONE Output: NONE author: socrates blog:http://blog.csdn.net/dyx1024 date:2012-03-09 ''' def __init__(self, filename): self.filename = filename def open_file(self): self.fobj = open(self.filename, 'w') def close_file(self): self.fobj.close() def onMouseEvent(self, event): "處理鼠標事件" self.fobj.writelines('-' * 20 + 'MouseEvent Begin' + '-' * 20 + '\n') self.fobj.writelines("Current Time:%s\n" % time.strftime("%a, %d %b %Y %H:%M:%S", time.gmtime())) self.fobj.writelines("MessageName:%s\n" % str(event.MessageName)) self.fobj.writelines("Message:%d\n" % event.Message) self.fobj.writelines("Time_sec:%d\n" % event.Time) self.fobj.writelines("Window:%s\n" % str(event.Window)) self.fobj.writelines("WindowName:%s\n" % str(event.WindowName)) self.fobj.writelines("Position:%s\n" % str(event.Position)) self.fobj.writelines('-' * 20 + 'MouseEvent End' + '-' * 20 + '\n') return True def onKeyboardEvent(self, event): "處理鍵盤事件" self.fobj.writelines('-' * 20 + 'Keyboard Begin' + '-' * 20 + '\n') self.fobj.writelines("Current Time:%s\n" % time.strftime("%a, %d %b %Y %H:%M:%S", time.gmtime())) self.fobj.writelines("MessageName:%s\n" % str(event.MessageName)) self.fobj.writelines("Message:%d\n" % event.Message) self.fobj.writelines("Time:%d\n" % event.Time) self.fobj.writelines("Window:%s\n" % str(event.Window)) self.fobj.writelines("WindowName:%s\n" % str(event.WindowName)) self.fobj.writelines("Ascii_code: %d\n" % event.Ascii) self.fobj.writelines("Ascii_char:%s\n" % chr(event.Ascii)) self.fobj.writelines("Key:%s\n" % str(event.Key)) self.fobj.writelines('-' * 20 + 'Keyboard End' + '-' * 20 + '\n') return True def InspectKeyAndMouseEvent(bRunTag = False): "" if bRunTag: my_event = CInspectKeyAndMouseEvent("D:\\hook_log.txt") my_event.open_file() #創建hook句柄 hm = pyHook.HookManager() #監控鍵盤 hm.KeyDown = my_event.onKeyboardEvent hm.HookKeyboard() #監控鼠標 hm.MouseAll = my_event.onMouseEvent hm.HookMouse() #循環獲取消息 pythoncom.PumpMessages() my_event.close_file() else: #程序走不到這里，直接在PumpMessages處不停地監聽 os._exit(0) def handle_start_InspecEvent(): "開始監控（按下Ctrl + F3）" InspectKeyAndMouseEvent(True) def handle_stop_InspecEvent(): "停止監控 (按下Ctrl + F4)" InspectKeyAndMouseEvent(False) if __name__ == "__main__": ''' Function:通過快捷鍵控制程序運行 Input：NONE Output: NONE author: socrates blog:http://blog.csdn.net/dyx1024 date:2012-03-09 ''' byref = ctypes.byref user32 = ctypes.windll.user32 #定義快捷鍵 HOTKEYS = { 1 : (win32con.VK_F3, win32con.MOD_CONTROL), 2 : (win32con.VK_F4, win32con.MOD_CONTROL) } #快捷鍵對應的驅動函數 HOTKEY_ACTIONS = { 1 : handle_start_InspecEvent, 2 : handle_stop_InspecEvent } #注冊快捷鍵 for id, (vk, modifiers) in HOTKEYS.items (): if not user32.RegisterHotKey (None, id, modifiers, vk): print "Unable to register id", id #啟動監聽 try: msg = wintypes.MSG () while user32.GetMessageA (byref (msg), None, 0, 0) != 0: if msg.message == win32con.WM_HOTKEY: action_to_take = HOTKEY_ACTIONS.get (msg.wParam) if action_to_take: action_to_take () user32.TranslateMessage (byref (msg)) user32.DispatchMessageA (byref (msg)) finally: for id in HOTKEYS.keys (): user32.UnregisterHotKey (None, id) ~~~ ### 二、測試 按下Ctrl + F3后，程序開始記錄日志，正常。 按下Ctrl + F4后，程序并沒有停止記錄日志，異常。因為在記錄日志時，啟動了pythoncom.PumpMessages()，不停地循環來獲取消息，程序不能繼續往下走。目前還沒有想到解決方案，明天接著想想看有沒有什么好的方法。
