sslobj.do_handshake失败和“错误：[Errno 0]错误”

时间：2016-07-01 13:23:40

标签： python django smtp ubuntu-14.04 pyopenssl

我在Ubuntu 14.04上运行了一个Django应用程序

当我使用请求模块或smtp模块并尝试建立加密连接时，我经常（并非总是，大部分时间都是这样）得到此错误：

错误：[Errno 0]错误

长错误（此处发送电子邮件）：

我不知道该怎么做。我在Ubuntu上安装了openssl，并作为python包。它是最新的。

我是否需要手动生成证书？ 这个问题与其他问题有关吗？

这就是我如何配置电子邮件：

EMAIL_USE_TLS = True
#EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.dd24.net'
EMAIL_HOST_PASSWORD = 'abcdef' 
EMAIL_HOST_USER = 'bp@example.com' 
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

感谢任何帮助。

经过长时间的研究，我发现它是加密模块中的一个错误。

请参阅： https://github.com/pyca/cryptography/issues/2299

的解决方法： 地点 WSGIApplicationGroup％{GLOBAL}

在apache virtualhost配置中 e.g。

<Directory /var/www/path/to/wsgi>
    <Files wsgi.py>
        Require all granted
    </Files>
    WSGIApplicationGroup %{GLOBAL}
</Directory>
