Python3编写Windows服务程序

最近做了公司签到的小工具，有同事要求做成Windows服务，开机自启。先说下怎么用Python写Windows服务程序。

 #encoding=utf-8
 import win32serviceutil
 import win32service
 import win32event
 import win32timezone
 import os

 class PythonService(win32serviceutil.ServiceFramework):
     _svc_name_ = 'PythonService' #服务名称
     _svc_display_name_ = 'regMeal'
     _svc_description_ = '每天晚上6：40后自动签到'

     def __init__(self,args):
         win32serviceutil.ServiceFramework.__init__(self,args)
         self.hWaitStop = win32event.CreateEvent(None,0,0,None)
         self.logger = self._getLogger()
         self.run = True

     def _getLogger(self):
         import inspect
         import logging
         logger = logging.getLogger('[PythonService]')
         this_file = inspect.getfile(inspect.currentframe())
         dirpath = os.path.abspath(os.path.dirname(this_file))
         handler = logging.FileHandler(os.path.join(dirpath,'service.log'))
         formatter = logging.Formatter('%(asctime)s  %(name)-12s %(levelname)-8s %(message)s')
         handler.setFormatter(formatter)
         logger.addHandler(handler)
         logger.setLevel(logging.INFO)
         return logger

     def SvcDoRun(self):
         import time
         import readconfig
         import regMeal
         self.logger.info('service is run...')
         while self.run:
             self.logger.info('service is running...')
             paraList = readconfig.readConfig()
             bFlag = regMeal.main(paraList[0],paraList[1],paraList[2])
             time.sleep(2)

     def SvcStop(self):
         self.logger.info('service is stop.')
         self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
         win32event.SetEvent(self.hWaitStop)
         self.run = False

 if __name__ == '__main__':
     import sys
     import servicemanager
     if len(sys.argv) == 1:
         try:
             evtsrc_dll = os.path.abspath(servicemanager.__file__)
             servicemanager.PrepareToHostSingle(PythonService)
             servicemanager.Initialize('PythonService',evtsrc_dll)
             servicemanager.StartServiceCtrlDispatcher()
         except win32service.error as details:
             import winerror
             if details == winerror.ERROR_FAILED_SERVICE_CONTROLLER_CONNECT:
                 win32serviceutil.usage()
     else:
         win32serviceutil.HandleCommandLine(PythonService)

推荐大家对比网上其他的人的代码对照看下。SvcDoRun这个函数里面放的就是你实际想做的事情。

安装服务

python PythonService.py install

让服务自动启动

python PythonService.py --startup auto install 

启动服务

python PythonService.py start

重启服务

python PythonService.py restart

停止服务

python PythonService.py stop

删除/卸载服务

python PythonService.py remove

我自己是用pyinstaller打包成exe给别人用的。

PS：脚本编好之后，调试了很久。刚开始会报服务无法启动的问题。具体的排查方式可以看Windows事件查看。
