大约2-3分钟后，芹菜抛出以下追溯：

尽管如此，当前任务的工人仍在继续工作。但是在我的Web应用程序中，我继续进行轮询URL，以获取当前任务的更新。在上述错误发生后，与RabbitMQ的连接似乎已关闭，以便该应用程序无法访问结果后端(RabbitMQ(。
我花了很多时间来弄清楚，到底会丢掉这个错误。我得出一个非常模糊的结论，可能是因为工人(目前正在使用：Eventlet，因为在Windows上运行(无法将心跳发送到RabbitMQ。但是我感到非常困惑，因为有些建议将心跳值配置为0(我在下面的配置中可以看到的那样(。另外，这无法解决问题。
这是我当前的配置，这是Github和Stackoverflow上所有最佳建议的绝望混合：
CELERY_BROKER_URL = 'pyamqp://'
CELERY_RESULT_BACKEND = 'amqp://'
CELERY_BROKER_TRANSPORT_OPTIONS = {'confirm_publish': True}
CELERY_BROKER_HEARTBEAT = 0
CELERY_BROKER_POOL_LIMIT = None
CELERY_BROKER_TRANSPORT_OPTIONS = {'confirm_publish': True}
CELERY_BROKER_CONNECTION_TIMEOUT = 20
CELERY_BROKER_CONNECTION_RETRY = True
CELERY_BROKER_CONNECTION_MAX_RETRIES = 100
CELERY_TIMEZONE = 'UTC'
CELERY_ENABLE_UTC = True
CELERY_IGNORE_RESULT = False
SQLALCHEMY_DATABASE_URI = userpass + basedir + dbname
SQLALCHEMY_TRACK_MODIFICATIONS = False
我希望，兔子和芹菜之间的连接稳定，没有连接错误。
暂时对我来说最大的问题是，我绝对不知道错误触发了什么。是一个工人不向RabbitMQ发送心跳吗？是兔子本身吗？
我为各种提示感到非常高兴。
编辑：忘了提到，我还读到这必须对主机名做点什么。我从芹菜开始：
芹菜-A任务。celeryWorker -loglevel = info-pool = eventlet -without-mingle-without-gossip -without-without heartbeat
它正在Localhost上运行(WebServer正在通过XAMPP运行(。如果我检查RabbitMQ控制台，则不是" Rabbit@localhost"，而是" Rabbit@Desktop-XXXX"。也许这导致错误？
从所有芹菜broker设置中删除芹菜前缀。为我工作。
这是我的CeleryConfig.py的片段：
BROKER_HEARTBEAT = 0
BROKER_POOL_LIMIT = None
BROKER_TRANSPORT_OPTIONS = {'confirm_publish': True}
BROKER_CONNECTION_TIMEOUT = 30
BROKER_CONNECTION_RETRY = True
