例子&＃xff1a;

#表示2017年3月22日17时19分07秒执行该程序
sched.add_job(my_job, &＃39;cron&＃39;, year&＃61;2017,month &＃61; 03,day &＃61; 22,hour &＃61; 17,minute &＃61; 19,second &＃61; 07)#表示任务在6,7,8,11,12月份的第三个星期五的00:00,01:00,02:00,03:00 执行该程序
sched.add_job(my_job, &＃39;cron&＃39;, month&＃61;&＃39;6-8,11-12&＃39;, day&＃61;&＃39;3rd fri&＃39;, hour&＃61;&＃39;0-3&＃39;)#表示从星期一到星期五5:30&＃xff08;AM&＃xff09;直到2014-05-30 00:00:00
sched.add_job(my_job(), &＃39;cron&＃39;, day_of_week&＃61;&＃39;mon-fri&＃39;, hour&＃61;5, minute&＃61;30,end_date&＃61;&＃39;2014-05-30&＃39;)#表示每5秒执行该程序一次&＃xff0c;相当于interval 间隔调度中seconds &＃61; 5
sched.add_job(my_job, &＃39;cron&＃39;,second &＃61; &＃39;*/5&＃39;)


2、 interval 间隔调度&＃xff08;每隔多久执行&＃xff09;

weeks (int) – number of weeks to wait
days (int) – number of days to wait
hours (int) – number of hours to wait
minutes (int) – number of minutes to wait
seconds (int) – number of seconds to wait
start_date (datetime|str) – starting point for the interval calculation
end_date (datetime|str) – latest possible date/time to trigger on
timezone (datetime.tzinfo|str) – time zone to use for the date/time calculations


例子&＃xff1a;

#表示每隔3天17时19分07秒执行一次任务
sched.add_job(my_job, &＃39;interval&＃39;,days &＃61; 03,hours &＃61; 17,minutes &＃61; 19,seconds &＃61; 07)


3、 date 定时调度&＃xff08;作业只会执行一次&＃xff09;

run_date (datetime|str) – the date/time to run the job at -&＃xff08;任务开始的时间&＃xff09;
timezone (datetime.tzinfo|str) – time zone for run_date if it doesn’t have one already


例子&＃xff1a;

# The job will be executed on November 6th, 2009
sched.add_job(my_job, &＃39;date&＃39;, run_date&＃61;date(2009, 11, 6), args&＃61;[&＃39;text&＃39;])
# The job will be executed on November 6th, 2009 at 16:30:05
sched.add_job(my_job, &＃39;date&＃39;, run_date&＃61;datetime(2009, 11, 6, 16, 30, 5), args&＃61;[&＃39;text&＃39;])
