1.异步任务
任务名.delay(传参数)
2.延迟任务
from datetime import datetime, timedelta
# atetime.utcnow() 当前utc时间
# 当前时间+15秒
eta = datetime.utcnow() + timedelta(seconds=15)
# 取消订单任务
res = cancel_order.apply_async(args=['10001',], eta=eta) # 15s 后执行这个任务
print(res)
3 定时任务 —— 需要启动beat
3.1 在celery.py 中配置
# 时区
app.conf.timezone = 'Asia/Shanghai'
# 是否使用UTC
app.conf.enable_utc = False
# 任务的定时配置
from datetime import timedelta
from celery.schedules import crontab
app.conf.beat_schedule = {
'send_sms': {
'task': 'celery_task.user_task.send_sms',
'schedule': timedelta(seconds=3), # 每隔3s执行一次
# 'schedule': crontab(hour=8, day_of_week=1), # 每周一早八点
'args': ('1896388888', '6666'),
}
}
3.2 启动worker
celery -A celery_task worker -l info -P eventlet
3.3 启动beat
celery -A celery_task beat -l info
