以windows service的方式运行Python程序

#!/usr/bin/env python# coding: utf-8# SmallestService.py## A sample demonstrating the smallest possible service written in Python.import win32serviceutilimport win32serviceimport win32eventimport timeclass SmallestPythonService(win32serviceutil.ServiceFramework):    _svc_name_ = "SmallestPythonService"    _svc_display_name_ = "The smallest possible Python Service"    def __init__(self, args):        win32serviceutil.ServiceFramework.__init__(self, args)        # Create an event which we will use to wait on.        # The "service stop" request will set this event.        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)    def SvcStop(self):        # Before we do anything, tell the SCM we are starting the stop process.        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)        # And set my event.        win32event.SetEvent(self.hWaitStop)    def SvcDoRun(self):        #把你的程序代码放到这里就OK了        f=open('d:\\log.txt','w',0)        f.write(time.ctime(time.time()))        f.close()        win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)if __name__=='__main__':    win32serviceutil.HandleCommandLine(SmallestPythonService)     # 括号里的名字可以改成其他的，必须与class名字一致；
