APSchedule 有时会错过一些触发器

问题描述

我正在尝试实施一个计划，该计划将全天运行，并且有开启时间和关闭时间。所以我不想在状态 1 下调用的方法在状态 1 中保持一段时间，而它们在状态 0 下调用相同的方法并保持另一个时期。所以基本上一盏灯会打开 1 分钟，它们会关闭 4 分钟，总是在状态之间切换。我已经尝试更改/修改工作，使用 Interval 和 Cron，它们都给了我同样的问题。所以问题是它会完美运行几个小时，并且他们无法触发事件一两次。有时它只是不触发。日志没有显示任何内容。

我制作了一个简单的代码片段用于测试：

import time
import logging
from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.events import EVENT_JOB_ERROR,EVENT_JOB_EXECUTED
from datetime import datetime

LOG_LEVEL = logging.INFO
LOG_FILE = "/var/log/test.log"
LOG_FORMAT = "%(asctime)s %(levelname)s %(message)s"
logging.basicConfig(filename=LOG_FILE,format=LOG_FORMAT,level=LOG_LEVEL)

def rele(on,off,state):
    print(str(datetime.Now()) + ': ' + str(state))
    state = str(1 - int(state))
    return on + ',' + off + ',' + state

def my_listener(event):
    if(event.exception):
        print('The job crashed: ' + event.job_id)
    else:
        splited = event.retval.split(',')
        jobid = event.job_id
        sched.remove_job(event.job_id)
        period = 1
        if(splited[2] == '0'):
            period = int(splited[0])
        else:
            period = int(splited[1])
        sched.add_job(rele,'interval',minutes=period,args=[splited[0],splited[1],splited[2]],id=jobid,misfire_grace_time=None)

sched = BackgroundScheduler(daemon=True)
sched.add_listener(my_listener,EVENT_JOB_EXECUTED | EVENT_JOB_ERROR)
sched.add_job(rele,minutes=1,args=['1','4','1'],id='rele1',misfire_grace_time=None)
sched.start()
print(str(datetime.Now()) + ": start")

while(True):
    time.sleep(.1)
