Question

我写了一个功能，通过芹菜异步运行任务，在本地进行测试，这一切都很好。运送到我的登台环境，当芹菜尝试使用以下回溯时，它会失败。

我甚至不确定如何调试此错误，因为它正在被celery调用，并且发生在python标准库中。有什么想法吗？

使用Celery的rdb进入框架，似乎没有设置套接字超时。

(Pdb) self.timeout
<Unset Timeout Value>

我有什么想法可以解决这个问题？错误来自Twilio - ＆gt; httplib2 - ＆gt; socket.py是_socket的包装器。这是我的头脑，甚至不确定如何处理这个问题。

Answer 1

默认情况下，Twilio的lib将超时设置为：

class _UnsetTimeoutKls(object):
    """ A sentinel for an unset timeout. Defaults to the system timeout. """
    def __repr__(self):
        return '<Unset Timeout Value>'


# None has special meaning for timeouts, so we use this sigil to indicate
# that we don't care
UNSET_TIMEOUT = _UnsetTimeoutKls()

因此，必须在实例化TwilioRestClient和实际的套接字调用之间发生一些事情，该套接字调用将_UnsetTimeoutKls评估为与None不同的内容。

初始化TwilioRestClient时将超时设置为无似乎可以解决错误：

self.client = TwilioRestClient(TWILIO_SID,
                    TWILIO_AUTH_TOKEN,
                    timeout=None)

Answer 2

这是发生了什么：

您告诉Twilio库创建短信。
Twilio转到httplib以连接到Twilio服务器。
httplib，在连接到Twilio服务器时，设置套接字的超时。

唯一的问题是，由于某种原因，倒数第二个堆栈帧中的self.timeout不是float所需的。您可能想尝试在Python调试器下运行您的应用程序，例如：

python -m pdb myapp.py

您将看到一个提示，您可以从中输入run来运行您的应用程序。一旦发生错误，它应该让你回到提示符。然后，您应该可以输入up，直到找到有问题的框架并查看self.timeout是什么。然后，您可能希望环顾四周，看看self.timeout设置的位置以及原因。然后，您应该可以通过修复该问题来解决问题。
