# 调度器
# 问题：Celery Received unregistered task of type
# 解决：我的flask的main.py文件和celery的主脚本task_timed_del_post.py在同一目录，
# 我的定时函数@celery.task(bind=True) def timed_del_post(self)也同时在该脚本中没有独立出去
# 下面的app是我工程项目的目录，在app里开始找，然后找到自己，然后找到函数timed_del_post
# 这里配置调度器和下面使用调度器效果一致
# "schedule": crontab(minute="*/1"),
application.config['beat_schedule'] = {
         "test001": {

def make_celery(app):

                return TaskBase.__call__(self, *args, **kwargs)
    celery.Task = ContextTask
    return celery

celery = make_celery(app.app)


# 核心函数
@celery.task(bind=True)
def timed_del_post(self):
    print("hello world!")

    return "ok"


# 运行方式：
# 服务器使用一个celery_service
# screen -S celery_service
# cd /root/backend/services/app
# 我的初始化celery对象叫做celery, 如果初始化叫做app，应该默认不写，叫别的名改别的名字
# celery -A app.task_timed_del_post.celery worker -B --loglevel=info
# celery -A app.task_timed_del_post worker -B -s /tmp/celerybeat-schedule --loglevel=info

　　

app文件夹下：

task_timed_del_post.py

timed_del_post函数在task_timed_del_post.py

 

更简单点的：

        },
    }

celery.conf.update(app.config)

    logger.debug('================')
    logger.debug('此处写需要定时调用的任务')
    logger.debug('================')
    print("hello world")
    return "ok"

# 服务器使用一个celery_service
