芹菜。从代码运行任务失败，无限“PENDING”状态

Question

我尝试根据文档设置所有内容，但失败了。

我检查了所有 this 时刻，它出现在输出中。

附言为方便起见，最好从代码中运行 celery。

tasks.py

from redis import Redis as redis_Redis
from celery import Celery


redis_drivers_queue = redis_Redis(db=0, port=6379, host='localhost')
redis_drivers_result = redis_Redis(db=1, port=6379, host='localhost')
app = Celery(main=__name__, broker='redis://localhost:6379/0', backend='redis://localhost:6379/1')
app.conf.humanize(with_defaults=False, censored=False)
app.conf.update(result_expires=3600)


@app.task
def foo():
    print(222)
    return 444

if __name__ == '__main__':
    app.worker_main([__name__, '--loglevel=DEBUG'])

main.py

import tasks


r = tasks.foo.delay()
r.status
'PENDING'  # Always
r.backend
<celery.backends.redis.RedisBackend object at 0x7f698fa3f910>
