Question

我正在尝试使用以下命令撤销芹菜任务。

revoke('d9078da5-9915-40a0-bfa1-392c7bde42ed', terminate=True, signal='SIGKILL')

revoke('d9078da5-9915-40a0-bfa1-392c7bde42ed', terminate=True)

revoke('d9078da5-9915-40a0-bfa1-392c7bde42ed')

这些都不起作用，我的工作池是eventlet：以

开头

$ celery -A scraper worker -P eventlet -c 1000 -l info

请告知如何执行此操作，因为我的django视图中有一个按钮，它使用任务I来取消任务。应该有办法做到这一点，但我不确定。使用prefork池它可以工作。

Answer 1

错误消息说Celery的TaskPool（Eventlet兼容版本）没有此功能。因此，您可以自己实施并向Celery团队发送补丁，也可以留下功能请求并等待。

复制prefork TaskPool代码并使其适应Eventlet API greenthread.kill()应该非常容易。

从django视图中取消或撤消eventlet中的celery任务
