一、简单任务

定义一个函数，然后定义一个scheduler类型，添加一个job，然后执行，就可以了

5秒整倍数，就执行这个函数

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime


def aps_test():
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), '你好')


scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, trigger='cron', second='*/5')
scheduler.start()

带参数的

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime


def aps_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)

scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, args=('你好',), trigger='cron', second='*/5')
scheduler.start()
# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime


def aps_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)

scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, args=('定时任务',), trigger='cron', second='*/5')
scheduler.add_job(func=aps_test, args=('一次性任务',), next_run_time=datetime.datetime.now() + datetime.timedelta(seconds=12))
scheduler.add_job(func=aps_test, args=('循环任务',), trigger='interval', seconds=3)

scheduler.start()

二、日志

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime
import logging

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S',
                    filename='log1.txt',
                    filemode='a')


def aps_test(x):
    print 1/0
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)

scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, args=('定时任务',), trigger='cron', second='*/5')
scheduler._logger = logging
scheduler.start()

三、删除任务

要求执行一定阶段任务以后，删除某一个循环任务，其他任务照常进行。有如下代码：

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime
import logging

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S',
                    filename='log1.txt',
                    filemode='a')


def aps_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)


def aps_date(x):
    scheduler.remove_job('interval_task')
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)
    

scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, args=('定时任务',), trigger='cron', second='*/5', id='cron_task')
scheduler.add_job(func=aps_date, args=('一次性任务,删除循环任务',), next_run_time=datetime.datetime.now() + datetime.timedelta(seconds=12), id='date_task')
scheduler.add_job(func=aps_test, args=('循环任务',), trigger='interval', seconds=3, id='interval_task')
scheduler._logger = logging

scheduler.start()

四、停止任务，恢复任务

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
import datetime
import logging

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S',
                    filename='log1.txt',
                    filemode='a')


def aps_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)


def aps_pause(x):
    scheduler.pause_job('interval_task')
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)


def aps_resume(x):
    scheduler.resume_job('interval_task')
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)

scheduler = BlockingScheduler()
scheduler.add_job(func=aps_test, args=('定时任务',), trigger='cron', second='*/5', id='cron_task')
scheduler.add_job(func=aps_pause, args=('一次性任务,停止循环任务',), next_run_time=datetime.datetime.now() + datetime.timedelta(seconds=12), id='pause_task')
scheduler.add_job(func=aps_resume, args=('一次性任务,恢复循环任务',), next_run_time=datetime.datetime.now() + datetime.timedelta(seconds=24), id='resume_task')
scheduler.add_job(func=aps_test, args=('循环任务',), trigger='interval', seconds=3, id='interval_task')
scheduler._logger = logging

scheduler.start()

五、捕获错误

# coding:utf-8
from apscheduler.schedulers.blocking import BlockingScheduler
from apscheduler.events import EVENT_JOB_EXECUTED, EVENT_JOB_ERROR
import datetime
import logging

logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
                    datefmt='%Y-%m-%d %H:%M:%S',
                    filename='log1.txt',
                    filemode='a')


def aps_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)


def date_test(x):
    print (datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'), x)
    print (1/0)


def my_listener(event):
    if event.exception:
        print ('任务出错了！！！！！！')
    else:
        print ('任务照常运行...')

scheduler = BlockingScheduler()
scheduler.add_job(func=date_test, args=('一定性任务,会出错',), next_run_time=datetime.datetime.now() + datetime.timedelta(seconds=15), id='date_task')
scheduler.add_job(func=aps_test, args=('循环任务',), trigger='interval', seconds=3, id='interval_task')
scheduler.add_listener(my_listener, EVENT_JOB_EXECUTED | EVENT_JOB_ERROR)
scheduler._logger = logging

scheduler.start()
