Question

我在python（windows XP）中创建了一个Windows服务，在这个服务中我运行了一个python服务器程序（带p = subprocess.Popen(Arg)），当我注销服务正在运行但我的应用程序停止了。什么是探索权，其他？有人能帮助我吗？

由于

源代码：

class PythonService(win32serviceutil.ServiceFramework):
    # you can NET START/STOP the service by the following name
    _svc_name_ = "PythonService"
    # this text shows up as the service name in the Service
    # Control Manager (SCM)
    _svc_display_name_ = "server service"
    # this text shows up as the description in the SCM
    _svc_description_ = "This service run a server"


    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self,args)
        # create an event to listen for stop requests on
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        servicemanager.LogInfoMsg("PythonService Service is starting")


    # core logic of the service   
    def SvcDoRun(self):   
        rc = None      
        PathPython = "c:/python2.6/python.exe"
        Script = "c:/PythonService/service.py"
        sJson = "c:/PythonService/service_static.json"


        Arg = [PathPython,Script,"-c",sJson] 
        process_arreter = 1

        try :
            # run a server
            p = subprocess.Popen(Arg)
        except OSError, why:
            msgerror = "PythonService Service is not running :" + os.strerror(why.errno) + " ["+PathPython+","+Script+","+sJson+"]"
            servicemanager.LogErrorMsg(msgerror)       
            return

        # if the stop event hasn't been fired keep looping
        servicemanager.LogInfoMsg("PythonService Service is running")
        while rc != win32event.WAIT_OBJECT_0:
            # block for 5 seconds and listen for a stop event
            rc = win32event.WaitForSingleObject(self.hWaitStop, 5000)
            if (p.poll()!=None):
                if process_arreter: 
                    servicemanager.LogWarningMsg("Server-Engine is stopped (failed)")
                process_arreter = 0

        if process_arreter:
            try:
                p.terminate()
                servicemanager.LogInfoMsg("Server-Engine is now stopped")
            except :
                pass


    # called when we're being shut down
    def SvcStop(self):
        # tell the SCM we're shutting down
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        # fire the stop event
        win32event.SetEvent(self.hWaitStop)
        servicemanager.LogInfoMsg("PythonService Service is stopped")



if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(PythonService)`

Answer 1

您的服务运行的用户是什么用户，是否拥有所有必需功能的权限？

服务不会在与用户相同的上下文中运行，除非您指定它们具有这些权限。

如果您在Windows服务中，则必须指定文件路径，并确保它们的路径具有读取权限但是没有完成，我无缘无故地把头发拉了出来。

# first try to get the currently logged on user
# works okay for a straight python app / prog
if sys.platform == 'win32':
     userName = os.getenv('USERNAME')
else: #linux but also not forgetting mac
      userName = os.getenv('USER')

# when code run in a python win service userName in None here!!!!
# so lets get platform specific
if not userName:
    if sys.platform == 'win32':
        import win32api
        userName = win32api.GetUserName()

# do you see 'SYSTEM' here - NOT the currently logged on user

要让您的服务在用户注销时继续运行，您需要指定一个在启动之前始终返回True的控制处理程序。

if __name__ == "__main__":
    win32api.SetConsoleCtrlHandler(lambda x: True, True)
    win32serviceutil.HandleCommandLine(PythonService)

注销Windows XP时，从python中的Windows服务运行的应用程序停止
