在文档中 link关于过期
# Task expires after one minute from now.
add.apply_async(args=[10, 10], expires=60)
我使用:
from tasks import add
result = add.apply_async(args=[10, 10], expires=6000)
printus(result)
def printus(result):
print (result) #task id
print (result.ready()) # returns True if the task has finished processing.
print (result.result) # task is not ready, so no return value yet.
print (result.get()) # Waits until the task is done and returns the retval.
print (result.result) # direct access to result, doesn't re-raise errors.
print (result.successful()) # returns True if the task didn't end in failure.)
任务.py
from celery.task import task
@task
def add(x, y):
return x + y
在 celery 中:
[2012-03-21 19:50:03,012: WARNING/MainProcess] Skipping revoked task: tasks.add[4ffcff91-b12b-4bce-8d47-159314759859]
在控制台中:

True

为什么会出现异常?结果还没过期
如果我使用:
result = add.apply_async(args=[10, 10])
一切顺利

最佳答案
celeryd 认为你的任务已经过期:
[2012-03-21 19:50:03,012: WARNING/MainProcess] Skipping revoked task: tasks.add[4ffcff91-b12b-4bce-8d47-159314759859]
当工作人员拿起过期任务时,it revokes it不执行。检查您的时区设置?我遇到了相反的问题:任务没有在应该到期的时候到期。这为我修好了:
CELERY_ENABLE_UTC = True
CELERY_TIMEZONE = 'Etc/UTC'
