导读 | Python 是一个高层次的结合了解释性、编译性、互动性和面向对象的脚本语言。 Python 的设计具有很强的可读性,相比其他语言经常使用英文关键字,其他语言的一些标点符号,它具有比其他语言更有特色语法结构。 |
使用threading写的一个定时器任务demo:
import time import sys import signal import datetime import threading
#定时器
def schedule_update(): t = threading.Timer(0, event_func) t.setDaemon(True) t.start()
#执行函数
def event_func(): now_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') print(now_time) exec_update() #update_openvas_dbs_from_cache() interval_time = delay_time() t = threading.Timer(interval_time, event_func) t.setDaemon(True) t.start()
#取时间点
def delay_time(): # now time now_time = datetime.datetime.now() # tomorrow time next_time = now_time + datetime.timedelta(days=+1) next_year = next_time.date().year next_month = next_time.date().month next_day = next_time.date().day # get tomorrow 00:00 next_time = datetime.datetime.strptime(str(next_year)+"-"+str(next_month)+"-"+str(next_day)+" 00:00:00", "%Y-%m-%d %H:%M:%S") # get secondes delay_time = (next_time - now_time).total_seconds() return delay_time def quit_sys(signum, frame): sys.exit()
#接收C
if __name__ == "__main__": try: signal.signal(signal.SIGINT, quit_sys) signal.signal(signal.SIGTERM, quit_sys) schedule_update() print("schedule_update server starting up.../nHit Ctrl-C to quit./n") while 1: time.sleep(1) except Exception as e: print(e)
