前一段做试验，需要远程监控现场的电脑；
写了一个定时截屏并把图片发送至邮箱的脚本，这样微信就可以得到通知。

1. 截屏，并保存图片

from PIL import ImageGrab
import time

time_now = time.strftime('%Y%m%d-%H%M%S')
pic = ImageGrab.grab()
pic_name = time_now+'.jpg'
pic.save(pic_name)

2. 定时任务

import threading

def func():
    t = time.localtime(time.time())
    min, hour, wkday = t.tm_min, t.tm_hour, t.tm_wday
    # --------add tasks here--------------------------
    if min in [0, 15, 30, 45]:
        print('tasks')   
    # --------tasks end----------------------------

    global timer
    timer = threading.Timer(60, func, [])
    timer.start()


timer = threading.Timer(1, func, [])
timer.start()

3.发邮件，将图片作为附件

    msg.attach(jpgpart)
    
    smtp.sendmail(sender, receiver, msg.as_string())
    smtp.quit()

PS1：去掉python程序的命令行窗口

把 *.py 文件后缀改成 *.pyw ，即可去掉运行时出现的cmd窗口，直接后台运行。

PS2：加入开机启动（Win10）

将 *.pyw 文件做一个快捷方式，放到开始菜单的启动文件夹
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
里，这样每次开机就能直接启动了。
