上一篇介绍了pywin32模块，它的win32service子模块提供了对服务管理API的包装，相关API如下：

 有了这些API，完成一些服务的基本操作，比如安装服务、停止服务、启动服务等完全不在话下，只不过都是直接调用API而已。

不过pywin32还有一个对win32service模块的包装，叫做 win32serviceutil，使用它可以更方便地对服务进行控制。

 

InstallService(pythonClassString, serviceName, displayName, startType = None,     errorControl = None, bRunInteractive = 0, serviceDeps = None, userName = None,     password = None, exeName = None, perfMonIni = None,perfMonDll = None,     exeArgs = None,description = None, delayedstart = None)  #安装服务ChangeServiceConfig(pythonClassString, serviceName, startType = None,     errorControl = None, bRunInteractive = 0, serviceDeps = None,     userName = None, password = None,exeName = None, displayName = None,     perfMonIni = None, perfMonDll = None,exeArgs = None,    description = None, delayedstart = None)  #更改服务设置#以上两个函数的第一个参数pythonClassString是为Python编写的Windows服务准备的，非Python服务则不需要，直接填None即可RemoveService(serviceName)  #删除服务ControlService(serviceName, code, machine = None)  #控制服务,code的具体定义参考MSDN的对ControlService的介绍StopService(serviceName, machine = None) #停止服务StartService(serviceName, args = None, machine = None) #启动服务RestartService(serviceName, args = None, waitSeconds = 30, machine = None) #重启服务QueryServiceStatus(serviceName, machine=None)  #查询服务状态

 

 大部分API只需要提供服务名称就可以了，调用起来非常简单。

比如 win32serviceutil.StopService("Spooler") 就可以停止Spooler服务了。

对于 win32serviceutil.QueryServiceStatus()这个函数，它实际返回的是win32service.QueryServiceStatus的返回结果。

从MSDN和pywin32的帮助文件可知，win32service.QueryServiceStatus的返回值是一个元组，如下：

SERVICE_STATUS ObjectA Win32 service status object is represented by a tuple:Items[0] int : serviceTypeThe type of service.[1] int : serviceStateThe current state of the service.[2] int : controlsAcceptedThe controls the service accepts.[3] int : win32ExitCodeThe win32 error code for the service.[4] int : serviceSpecificErrorCodeThe service specific error code.[5] int : checkPointThe checkpoint reported by the service.[6] int : waitHintThe wait hint reported by the service

 服务状态实际上是第1个元素（从0开始计数）

写个函数包装一下，并附带上控制功能：

import win32serviceimport win32serviceutilimport win32apidef GetSvcStatus(svcname):    svcstatusdic = {    #The service continue is pending.    win32service.SERVICE_CONTINUE_PENDING:"continue pending",     #The service pause is pending.    win32service.SERVICE_PAUSE_PENDING:"pause pending",    #The service is paused.    win32service.SERVICE_PAUSED:"paused" ,     #The service is running.    win32service.SERVICE_RUNNING:"running",    #The service is starting.    win32service.SERVICE_START_PENDING:"start pending",     # The service is stopping.    win32service.SERVICE_STOP_PENDING:"stop pending" ,    #The service is not running.    win32service.SERVICE_STOPPED:"stoped"    }    status = win32serviceutil.QueryServiceStatus(svcname)    if status:        return svcstatusdic.get(status[1],"unknown")    else:        return "error"svcname = "Spooler"status = GetSvcStatus(svcname)print("{} current status : {}".format(svcname,status))if status == "running":    win32serviceutil.StopService(svcname)else:    win32serviceutil.StartService(svcname)win32api.Sleep(1000)status = GetSvcStatus(svcname)print("After Control,{} current status : {}".format(svcname,status))

输出结果如下：

掌握该模块的使用，对Windows平台的运维管理还是有相当帮助的。
