在 Python 中检测 Windows 注销 [英] Detect windows logout in Python

问题描述

当 windows 在 python 中注销时，我如何检测或得到通知?

How can I detect, or be notified, when windows is logging out in python?

Martin v. Löwis 的回答很好，适用于完全注销，但不适用于快速用户切换"事件，例如按 win+L，这正是我真正需要的.

我没有使用作为服务运行的 gui

Martin v. Löwis' answer is good, and works for a full logout but it does not work for a 'fast user switching' event like pressing win+L which is what I really need it for.

im not using a gui this is running as a service

推荐答案

您可以使用终端服务 API 检测快速用户切换事件，您可以使用 win32ts 模块从 Python 访问它href="http://sourceforge.net/projects/pywin32/" rel="noreferrer">pywin32.在 GUI 应用程序中，调用 WTSRegisterSessionNotification 以接收通知消息，WTSUnRegisterSessionNotification 停止接收通知，并处理 WM_WTSSESSION_CHANGE 窗口过程中的消息.

You can detect fast user switching events using the Terminal Services API, which you can access from Python using the win32ts module from pywin32. In a GUI application, call WTSRegisterSessionNotification to receive notification messages, WTSUnRegisterSessionNotification to stop receiving notifications, and handle the WM_WTSSESSION_CHANGE message in your window procedure.

如果您使用 Python 编写 Windows 服务，请使用 RegisterServiceCtrlHandlerEx 函数检测快速用户切换事件.这在 pywin32 库中作为 servicemanager 模块中的 RegisterServiceCtrlHandler 函数可用.在您的处理程序函数中，查找SERVICE_CONTROL_SESSIONCHANGE 通知.另请参阅 WM_WTSSESSION_CHANGE 文档，了解有关具体的通知代码.

If you're writing a Windows service in Python, use the RegisterServiceCtrlHandlerEx function to detect fast user switching events. This is available in the pywin32 library as the RegisterServiceCtrlHandler function in the servicemanager module. In your handler function, look for the SERVICE_CONTROL_SESSIONCHANGE notification. See also the WM_WTSSESSION_CHANGE documentation for details of the specific notification codes.
