python定时任务windows服务
    
    
    一、python调用外部exe文件
    import subprocess
    subprocess.call('notepad')
    
    
    import subprocess
    #字符串中含有空格，所以有 r''
    subprocess.call("D:\Program Files (x86)\Netease\CloudMusic\cloudmusic.exe")
    
    二、定时任务
    pip install py-task
    
    
    from task import task
    from task import task_container
    from task.job import job
    from task.trigger import cron_trigger
    
    class MyJob(job.Job):
        def __init__(self):
            pass
    
        def execute(self):
            print 'Hello now is ' + str(time.time())
    
    cron = '0-59/5 10,15,20 * * * * 2015'
    new_task = task.Task('Task', MyJob(), cron_trigger.CronTrigger(cron))
    container.add_task(new_task)
    container.start_all()
    
    
    三、python开发windows服务
    
    一个简单的服务模版：
    #encoding=utf-8  
    #ZPF  
    import win32serviceutil   
    import win32service   
    import win32event   
    
    class PythonService(win32serviceutil.ServiceFramework):   
        #服务名  
        _svc_name_ = "PythonService"  
        #服务在windows系统中显示的名称  
        _svc_display_name_ = "Python Service Test"  
        #服务的描述  
        _svc_description_ = "This code is a Python service Test"  
    
        def __init__(self, args):   
            win32serviceutil.ServiceFramework.__init__(self, args)   
            self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)  
    
        def SvcDoRun(self):  
            # 把自己的代码放到这里，就OK  
            # 等待服务被停止   
            win32event.WaitForSingleObject(self.hWaitStop, win32event.INFINITE)   
    
        def SvcStop(self):   
            # 先告诉SCM停止这个过程   
            self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)   
            # 设置事件   
            win32event.SetEvent(self.hWaitStop)   
    
    if __name__=='__main__':   
        win32serviceutil.HandleCommandLine(PythonService)    
        #括号里参数可以改成其他名字，但是必须与class类名一致；  
    
    
    服务示例：
    #ZPF  
    #encoding=utf-8  
    import win32serviceutil   
    import win32service   
    import win32event  
    import os   
    import logging  
    import inspect   
    
    class PythonService(win32serviceutil.ServiceFramework):   
    
        _svc_name_ = "PythonService"  
        _svc_display_name_ = "Python Service Test"  
        _svc_description_ = "This is a python service test code "  
    
        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):  
    
            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  
            self.logger.info("service is run....")   
            while self.run:  
                self.logger.info("I am runing....")  
                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__':
        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, details:
               if details[0] == winerror.ERROR_FAILED_SERVICE_CONTROLLER_CONNECT:
                   win32serviceutil.usage()
       else:
           win32serviceutil.HandleCommandLine(PythonService)
    
    
    
    四、pyinstaller 打包为控制台文件
    
    if __name__ == '__main__':
        from PyInstaller.main import run
        params=['windows_services_in_python.py', '-F', '-c', '--icon=favicon.ico']
        run(params)
    
    cmd进入exe所在目录：
    windows_services_in_python.exe install
    
    windows_services_in_python.exe start
    
    
    五、python操作window服务
    
    1.安装服务
    python PythonService.py install  
    
    2.让服务自动启动
    python PythonService.py --startup auto install   
    
    3.启动服务
    python PythonService.py start  
    
    4.重启服务
    python PythonService.py restart  
    
    5.停止服务
    python PythonService.py stop  
    
    6.删除/卸载服务
    python PythonService.py remove
