通过Python3在Mac上检测锁定屏幕 [英] Detecting lock screen on Mac through Python3

问题描述

试图找到一种使用Python3检测屏幕是否在Mac系统上锁定的方法

Trying to find a way to detect if the screen is locked on a Mac system, using Python3

我尝试了以下操作，它给出了KeyError:

I've tried the following, and it gives a KeyError:

import Quartz
gui_dict = Quartz.CGSessionCopyCurrentDictionary()
print(gui_dict['CGSSessionScreenIsLocked'])

import Quartz
all_windows = Quartz.CGWindowListCopyWindowInfo(Quartz.kCGWindowListOptionOnScreenOnly, Quartz.kCGNullWindowID)
for x in all_windows:
    if x["kCGWindowOwnerName"] == "loginwindow"
        print("Locked!")

此代码可在Python2上运行，但考虑到需要使用/usr/bin/python来导入Quartz，因此不适用于此代码.

This code works on Python2, but not 3 considering /usr/bin/python needs to be used to import Quartz.

推荐答案

安装quartz-
pip install pyobjc-framework-Quartz

很多简单的代码-

import Quartz
d = Quartz.CGSessionCopyCurrentDictionary()
print('CGSSessionScreenIsLocked' in d.keys())
