sslobj.do_handshake failure and “error: [Errno 0] Error”
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(不总是,主要是每隔一次)收到此错误:
错误:[errno 0]错误
长错误(这里是发送电子邮件的错误):

我不知道在这里做什么。我在Ubuntu上安装了openssl,并将其作为python包。它是最新的。
我需要手动生成证书吗?这个问题与其他问题有关吗?
这就是我配置电子邮件的方式:
1 2 3 4 5 6 7 | EMAIL_USE_TLS = True #EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.dd24.net' EMAIL_HOST_PASSWORD = 'abcdef' EMAIL_HOST_USER = '[email protected]' EMAIL_PORT = 587 DEFAULT_FROM_EMAIL = EMAIL_HOST_USER |
感谢您的帮助。
经过长时间的研究,我在密码模块中发现了一个漏洞。
