芹菜会默认拒绝泡菜，我应该禁用它吗？

Question

我刚刚设置了我的第一个芹菜实例，出于安全考虑，我收到了禁用pickle作为序列化程序的警告。关掉它的后果是什么？芹菜需要连续器干什么？

If you depend on pickle then you should set a setting to disable this warning and to be sure that everything will continue working when you upgrade to Celery 3.2::

CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack', 'yaml']

Answer 1

来自http://celery.readthedocs.org/en/latest/faq.html#is-celery-dependent-on-pickle：

The default serialization format is pickle simply because it is convenient (it supports sending complex Python objects as task arguments).

无论是否使用pickle，您都可能希望通过设置CELERY_ACCEPT_CONTENT配置变量来关闭此警告。

如果在任务中不使用Python对象作为参数，则应考虑使用安全的，例如json序列化格式。

pickle的另一个限制是没有任务结果-请参见http://docs.celeryproject.org/en/latest/faq.html#isn-t-using-pickle-a-security-concern：

For the task messages you can set the CELERY_TASK_SERIALIZER setting to “json” or “yaml” instead of pickle. There is currently no alternative solution for task results (but writing a custom result backend using JSON is a simple task)
