排队调用中的rq超时参数不起作用，给出JobTimeoutException

Question

我正在尝试更改RQ工作的超时时间，但是似乎没有任何效果。我有一些效果：

my_queue = Queue('my_task', connection=Redis())

job_args = (1, 2, 4)

my_queue.enqueue_call(
                    my_func,
                    args=job_args,
                    timeout=2700
            )

但我仍然

JobTimeoutException: Job exceeded maximum timeout value (180 seconds)

我非常拼命，甚至尝试进入rq模块queue.py并将超时的默认参数更改为2700和DEFAULT_TIMEOUT（在Queue类中定义的变量，其中包含enqueue_call方法）。我是否缺少任何东西？有人知道吗？谢谢！

Answer 1

我们可以通过在队列初始化时设置超时来解决这个问题。

from rq import Worker, Queue, Connection
q = Queue(default_timeout=3600)

希望这能解决您的疑问。

enqueue_call 中的超时参数没有问题。刚刚用这个例子测试了一下。

函数.py

from time import sleep
def test(a, b, c):
    sleep(a)
    print str(b+c)

驱动程序.py

from redis import Redis
from rq import Queue
from function import test

q = Queue('abc', connection=Redis())

q.enqueue_call(test, args=(300, 2, 3), timeout=200)
q.enqueue_call(test, args=(100, 2, 3), timeout=200)

结果：

13:08:11 abc: test.test(100, 2, 3) (4b4e96e5-af30-4175-ab94-ceaf9187e581)

13:08:13 abc: test.test(300, 2, 3) (04605c34-d039-42ad-954e-7f445f0f8bc9)

如果您使用supervisor等工具来管理rq工作人员，请尝试重新启动服务。
