python apscheduler 不是每 1 分钟由 cron 执行一次

Question

I am using apscheduler to make a cron job, now I want to make the work execute every 1 minute. This is my code:

# -*- coding: utf-8 -*-
import time

from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.triggers.interval import IntervalTrigger


if __name__ == '__main__':
    scheduler = BackgroundScheduler()
    scheduler.start()
    try:
        while True:
            time.sleep(2)
    except (KeyboardInterrupt, SystemExit):
        scheduler.shutdown()


@scheduler.scheduled_job(IntervalTrigger(seconds=60))
def func_to_be_executed():
    print("I am running......")

But the job only execute once, what should I to to make it execute every minute using cron way?

Answer 1

Try using the decorator approach. It should work.

from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.triggers.interval import IntervalTrigger

scheduler = BackgroundScheduler()
scheduler.start()

@scheduler.scheduled_job(IntervalTrigger(seconds=60))
def func_to_be_executed():
  pass

Code for BlockingSchedular - use when the scheduler is the only thing running in your process

from apscheduler.schedulers.blocking import BlockingScheduler
from apscheduler.triggers.interval import IntervalTrigger

sched = BlockingScheduler()

@sched.scheduled_job(IntervalTrigger(seconds=10))
def timed_job():
    print('This job is run every 10 seconds.')

sched.start()
