最近在 SSL 3 中发现了一个漏洞，Apple 决定将其关闭以用于推送通知 (APNS)。以下是2014 年 10 月 22 日发布的公告。

在过去的几天里，我的开发推送服务器一直在崩溃，出现以下异常：

Traceback (most recent call last):

我怎样才能解决这个问题？有没有办法告诉 apns-client 避免使用 SSL 3 而使用 TLS？

有人为 apns-client 创建了一个补丁，使其默认为 TLS，这是 Apple 推荐的未来解决方案。它肯定会很快合并。

希望这可以帮助。

如果您不想/不能使用该补丁，您可以随时使用猴子补丁/破解它：

import OpenSSL
OpenSSL.SSL.SSLv3_METHOD = OpenSSL.SSL.TLSv1_METHOD # work-around for apns-client's inability to specify ssl version combined w/apple's turning off of v3 due to POODLE attack
from apnsclient import Session, Message, APNs  # this line must follow the OpenSSL hack line!!!!
