我在芹菜doc下的情況下進行測試，但提升不正確配置異常。 http://docs.celeryproject.org/en/master/userguide/calling.html#id3芹菜提升不當配置異常
Traceback (most recent call last):
File "test.py", line 8, in <module> print(r.get(on_message=on_raw_message, propagate=False))
File "/usr/local/python2.7/lib/python2.7/site-packages/celery/result.py", line 189, in get on_message=on_message,
File "/usr/local/python2.7/lib/python2.7/site-packages/celery/backends/base.py", line 460, in wait_for_pending 'Backend does not support on_message callback')
celery.exceptions.ImproperlyConfigured: Backend does not support on_message callback
測試代碼：
from celery_test.agent import hello
from celery_test.celery import app
def on_raw_message(body):
print(body)
r = hello.apply_async(args=[122,34], queue='machine1', routing_key='machine1')
print(r.get(on_message=on_raw_message, propagate=False))
芹菜-A的輸出celery_test報告

能否請你加'芹菜-A報告有問題的輸出？ –
@ssudake已經添加芹菜的輸出-A report' –
我不確定rabbitmq後端是否支持'on_message'回調。這似乎是芹菜代碼最近的變化。請看[https://github.com/celery/celery/pull/3477/files](https://github.com/celery/celery/pull/3477/files） –
