芹菜打败不工作

Question

Celery beat没有正确安排任务并冻结。

Celery配置4.1.0

CELERY_BROKER_URL = 'redis://127.0.0.1:6379'
CELERY_ACCEPT_CONTENT = ['application/json']
CELERY_RESULT_SERIALIZER = 'json'
CELERY_TASK_SERIALIZER = 'json'
CELERY_TIMEZONE = 'Asia/Kolkata'
CELERY_ACCEPT_CONTENT += ['pickle']
CELERYBEAT_SCHEDULE = {
    'testing_msg': {
        'task': 'modules.sms.tasks.testing_message',
        'schedule': crontab(minute=1),
    },
}

tasks.py

@task()
def testing_message(*args, **kwargs):
    SmsAPI().send_sms("Hello Shubham Message Time is {}".format(datetime.now().time()), "958xxxxxx")
    SmsAPI().send_sms("Hello Nishant Message Time is {}".format(datetime.now().time()), "971xxxxxx")
