如何强制python apns-client避免使用SSL 3？

Question

最近在SSL 3中发现了一个漏洞,Apple决定将其关闭以进行推送通知(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因此异常而崩溃:

Traceback (most recent call last):

    raise exceptionType(errors)
OpenSSL.SSL.Error: [('SSL routines', 'SSL3_READ_BYTES', 'sslv3 alert handshake failure')]

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并使用TLS？

Answer 1

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

希望这可以帮助.
