Python 3.2 Cherrypy 3.2.3 ssl_module pyopenssl 错误

Question

我正在使用 Raspberry Pi 的 SSL 协议(protocol)和 Gandi 的签名证书 运行网络服务器。

服务器使用配置中的 ssl_module = 'builtin'。但是由于浏览器在识别证书颁发者方面存在问题，我需要通过 ssl_certificate_chain 属性提供中间证书，这只能通过使用 ssl_module = 'pyopenssl' .但是这个配置不起作用。 (查看错误信息)

pyOpenSSL 已安装。但是当我做测试时:

'>>>import ssl

'>>>import socket

'>>>hasattr(socket, 'ssl')

False

我还尝试在使用 pip-3.2 安装 libssl-dev 后重建 Python3.2。但是我没有成功，不得不恢复整个系统。

感谢您的帮助!

至少对于几个 CherryPy 版本 ssl_builtin supports certificate_chain .从 Cheese Shop 安装 CherryPy 3.7+(即 pip install CherryPy)，而不是从 Debian Pacakges。 Python 3.2 本身是一个很好的更新候选者(例如，许多库是 3.3+)。

另请查看 this answer了解当前的 CherryPy SSL 问题。或者 this section直接，因为 CherryPy 目前不支持 Python 3 的 PyOpenSSL。
