问题描述:
我创建了一个Windows服务在Python(Windows XP中),在这个服务我运行一个Python服务器程序(与p = subprocess.Popen(Arg)
),当我注销服务正在运行,但我的应用程序停止。 什么是探针权利,其他? 有人可以帮我吗?应用程序运行从Windows服务在python停止注销时Windows XP
感谢

正在运行的用户服务作为,和它的权限,它的所有需要的功能?
服务不会与用户在同一上下文中运行,除非您指定它们具有这些权限。
如果你在一个Windows服务中,你必须指定你的文件路径,并确保它们的路径有权被读取为 ,但它没有完成,我无缘无故地将我的头发拉出来。

# 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

为了让您的服务继续运行,即使用户注销时需要指定的控制处理程序,它会一直开始之前返回True
。
if __name__ == "__main__":
win32api.SetConsoleCtrlHandler(lambda x: True, True)
win32serviceutil.HandleCommandLine(PythonService)
George,我的服务以管理员权限运行,python projet安装了管理员权限;我认为必须陷入注销事件,以避免服务器停止。 – louis 2012-07-23 19:56:47
我知道这将是一个奇怪的问题,但确切地说,“你如何开始和停止服务”? – 2012-07-24 06:54:27
