Question

所以我正在创建一个密码管理器，作为一项安全功能，我想添加会话时间，在一段时间不活动（在示例代码中为 3 秒）后将用户注销，我有这个代码：

import os
import time
import threading

# Checks what OS you're using
def check_platform():
    if os.name == "nt":
        platform = "Windows"
    else:
        platform = "Linux"
    return platform


# Starts inactivity timer
def start_timer():
    platform = check_platform()
    if platform == "Windows":
        def timer_start():
            while True:
                time.sleep(1)
                check_if_idle_windows()
        thread1 = threading.Thread(target=timer_start)
        thread1.start()
    elif platform == "Linux":
        def timer_start():
            while True:
                time.sleep(1)
                check_if_idle_linux()
        thread1 = threading.Thread(target=timer_start)
        thread1.start()


# Checks if the user is idle on Windows
def check_if_idle_windows():
    import win32api
    idle_time = (win32api.GetTickCount() - win32api.GetLastInputInfo()) / 1000.0
    if idle_time > 3:
        os.system("cls")
        print("You have been logged out due to inactivity.")
        os._exit(0)


# Checks if the user is idle on Linux
def check_if_idle_linux():
    ### Code to get idle time here ###
    if idle_time > 3:
        os.system("clear")
        print("You have been logged out due to inactivity.")
        os._exit(0)


def random_function_for_main_thread():
    while True:
        my_string = input("Enter something or stay inactive for 3 seconds : ")
        print("You entered something.")


def main():
    start_timer()
    random_function_for_main_thread()


if __name__ == "__main__":
    main()

我可以用什么来获得 Linux 上的空闲时间？我尝试了 this 和 this，但都没有奏效。希望不要重复我的问题，谢谢。

    if idle_time > 3:
        os.system("cls")
        print("You have been logged out due to inactivity.")
        os._exit(0)


# Checks if the user is idle on Linux
def check_if_idle_linux():
    import subprocess
    idle_time = int(subprocess.getoutput('xprintidle')) / 1000 # Requires xprintidle (sudo apt install xprintidle)
    if idle_time > 3:
        os.system("clear")
        print("You have been logged out due to inactivity.")
        os._exit(0)


def random_function_for_main_thread():
    while True:
        my_string = input("Enter something or stay inactive for 3 seconds : ")
        print("You entered something.")


def main():
    start_timer()
    random_function_for_main_thread()


if __name__ == "__main__":
    main()
