Question

我正在尝试发送电子邮件，但显示如下错误。谁能告诉我怎么了？以上是原始代码。我已经尝试过TLS 465和SMTP 587。但结果相同，连接被拒绝。

这里是代码：

    from threading import Thread
    from flask import Flask
    from flask_mail import Mail, Message
    from config import config
    from instance.config import *

    app = Flask(__name__)


    def send_async_email(msg):
        mail = Mail(app) 
        with app.app_context():
            mail.send(msg)
    def send_email(to, subject, template, **kwargs):
        app.config.from_object(config['default'])
        app.config.from_pyfile('config.py')

        msg = Message(MAIL_SUBJECT_PREFIX + ' ' + subject,
                      sender=MAIL_SENDER, recipients=[to],html='templates/email/inform.html')
        thrmail = Thread(target=send_async_email, args=[msg])
        thrmail.start()
        return thrmail

这是错误：

Answer 1

首先，使用flask-mail发送邮件，您应该拥有这些内容

1.smtp服务器-如果您有像postfix这样的本地smtp服务器，没有问题，或者您必须测试邮件服务器，请转到此链接并创建免费帐户以获取免费的smtp服务器ip和配置详细信息.. https://mailtrap.io

您必须在您的防火墙中打开smtp端口。

在配置了那些尝试使用正确的配置详细信息运行您的程序之后

Answer 2

以下配置对我有用。请尝试使用此配置：

MAIL_SERVER='smtp.gmail.com'
MAIL_PORT=465
MAIL_USE_TLS = False
MAIL_USE_SSL= True
MAIL_USERNAME = 'yourmail@gmail.com'
MAIL_PASSWORD = 'yourpassword'

也不要忘记允许“安全性较低的应用”访问您的帐户。请参阅此link。

Flask_mail连接被拒绝
