私はPython(Windows XP)でWindowsサービスを作成しました。このサービスでは、Pythonサーバープログラム(を使用p = subprocess.Popen(Arg))を実行します。ログオフすると、サービスは実行されますが、アプリケーションは停止します。プローブムとは何ですか、他ですか?誰かが私を助けることができますか?

ありがとう

ソースコード :

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")

# 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

あなたのサービスはどのユーザーとして実行されており、必要なすべての機能へのアクセス許可を持っていますか?

これらの権限を持つように指定しない限り、サービスはユーザーと同じコンテキストで実行されません。

Windowsサービス内にいる場合は、ファイルパスを指定する必要があります。パスに読み取りと書き込みの許可があることを確認してください。
