在 Python 中检测计算机/程序关闭? [英] Detecting computer/program shutdown in Python?

问题描述

我有一个 Python 脚本，它定期循环运行，对我的照明系统进行调整.当我关闭计算机时，我希望我的脚本能够检测到这一点，然后将灯完全关掉.

I have a Python script that runs in a loop regularly making adjustments to my lighting system. When I shut down my computer, I'd like my script to detect that, and turn off the lights altogether.

如何检测我的计算机开始在 Python 中关闭?

How do I detect my computer beginning to shut down in Python?

或者，假设 Windows 向 Python 发送关闭时间"通知，我如何拦截它以关闭我的灯并退出循环?

Or, assuming Windows sends Python a "time to shut down" notice, how do I intercept that to kill my lights and exit the loop?

推荐答案

你应该对 WM_ENDSESSION 消息.

You should react to the WM_ENDSESSION message.

当用户注销或计算机关闭时发送此消息.

This message is sent when the user logs off or the computer gets shut down.

如果您还想对睡眠/休眠做出反应，则需要处理 WM_POWERBROADCAST 和 PBT_APMSUSPEND.

If you want to react to Sleep/Hibernate as well, you'll need to handle WM_POWERBROADCAST with PBT_APMSUSPEND.

但我不知道如何在 python 中做到这一点.我想这取决于您的窗口框架，因为您需要有一个窗口/消息循环来接收消息.

But I don't know how to do that in python. I guess it depends on your windowing framework since you need have a windows/a message loop to receive messages.
