我尝试用RabbitMQ（3.8.19）（Django 4.1.5）设置Celery（5.2.7），结果，任务出现在“celery”队列中，状态为“Unacked”，30分钟后，它进入“Ready”状态，并显示一条消息。“amqp.exceptions.PreconditionFailed：（0，0）：（406）PRECONDITION_FAILED -通道1上的传递确认超时。使用的超时值：1800000毫秒。此超时值可以配置，请参阅消费者文档指南了解更多信息”
当直接调用该方法时（不带.delay），一切都正常工作。
我不知道哪些配置不正确
celery ：$celery -我的本地工人-l信息

尝试以相同效果使用配置：已添加到settings.py:

CELERY_RESULT_BACKEND = 'rpc://'

$ celery -A mylocal worker -l info -E
