from tornado import web, ioloop import datetime period = 5 * 1000 # every 5 s class MainHandler(web.RequestHandler): def get(self): self.write(‘Hello Tornado‘) def like_cron(): print datetime.datetime.now() def xiaorui(): print ‘xiaorui 2s‘ def lee(): print ‘ wansuilee 3s‘ if __name__ == ‘__main__‘: application = web.Application([ (r‘/‘, MainHandler), ]) application.listen(80) ioloop.PeriodicCallback(like_cron, period).start() # start scheduler ioloop.PeriodicCallback(xiaorui, 1000).start() # start scheduler ioloop.PeriodicCallback(lee, 3000).start() # start scheduler ioloop.IOLoop.instance().start()
tornado 在启动时候，启动1个线程，实现crontab的功能
