Flask电子邮件支持 - 发送电子邮件时获取SSLError [Errno 1] [英] Flask Email Support - Get SSLError [Errno 1] when sending email

问题描述

我正在为Flask应用程序设置一个电子邮件服务器。我得到一个SSLError这是我第一次学习任何类型的网页开发。

I'm trying to set up an email server for a Flask app. I'm getting an SSLError. This is my first time learning any sort of web development.

以下是我如何配置服务器：

Here is how I've configured the server:

# mail server settings
MAIL_SERVER = 'smtp.mail.yahoo.com'
MAIL_PORT = 587
MAIL_USE_TLS = False
MAIL_USE_SSL = True
MAIL_USERNAME = '[e-mail]'
MAIL_PASSWORD = 'password'


# administrator list
ADMINS = ['[e-mail]']

这里是我的 init 脚本处理邮件的一部分：

And here is the part of my init script that deals with mail:

app.config.from_object('config')
mail = Mail(app)

当我尝试发送电子邮件时，这是错误的回溯：

Here is the traceback of the error when I try to send an email:

Traceback (most recent call last):

    new_socket = ssl.wrap_socket(new_socket, self.keyfile, self.certfile)

    self._sslobj.do_handshake()   
ssl.SSLError: [Errno 1] _ssl.c:504: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

谢谢！

推荐答案

MAIL_PORT = 587
MAIL_USE_TLS = False
MAIL_USE_SSL = True

端口587用于exp合法的TLS（STARTTLS命令），所以你可能必须使用MAIL_USE_TLS而不是MAIL_USE_SSL。 MAIL_USE_SSL用于隐式TLS，您可以直接使用端口465上的TLS连接。

Port 587 is for explicit TLS (STARTTLS command) so you probably have to use MAIL_USE_TLS and not MAIL_USE_SSL. MAIL_USE_SSL is for implicit TLS where you directly connect with TLS on port 465.
