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。
