我想在我的 web 应用程序中使用烧瓶邮件，但我遇到了我不太了解的错误。一直遵循指导方针，但无法让它发挥作用。在以下过程中，我希望应用程序向新注册用户发送电子邮件。
配置：
MAIL_SERVER='smtp.gmail.com',
MAIL_PORT=465,
MAIL_USE_SSL=True,
MAIL_USE_TLS=False,
MAIL_USERNAME = 'myMail@gmail.com',
MAIL_PASSWORD = '******'
看法：
from flask_mail import Mail, Message
mail = Mail(app)
@app.route("/send_mail/")
def send_mail():
msg = Message('Hello', sender = 'myMail@gmail.com', recipients = ['somebody@gmail.com'])
msg.body = "This is the email body"
mail.send(msg)
我得到的错误：
