问题描述

有关过期的文档链接

# 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.)

tasks.py

from celery.task import task
@task
def add(x, y):
    return x + y

芹菜:

在控制台中:

4ffcff91-b12b-4bce-8d47-159314759859
True

Traceback (most recent call last):

    raise self.exception_to_python(meta["result"])
celery.exceptions.TaskRevokedError

为什么会出现异常?结果尚未过期

Why do I get an exception? The result has not expired

如果我使用:

result = add.apply_async(args=[10, 10])

一切正常

推荐答案

celeryd认为您的任务已过期:

celeryd thinks your task has expired:

[2012-03-21 19:50:03,012: WARNING/MainProcess] Skipping revoked task: tasks.add[4ffcff91-b12b-4bce-8d47-159314759859]

当工人拿起过期任务时，它将其撤销而不执行.检查您的时区设置?我遇到了一个相反的问题:任务应该在什么时候到期.这对我来说是固定的:

When an expired task is picked up by a worker, it revokes it without executing. Check your timezone settings? I had the inverse problem: tasks weren't expiring when they should have. This fixed it for me:

CELERY_ENABLE_UTC = True
CELERY_TIMEZONE = 'Etc/UTC'
