我正在Heroku上创建一个Flask应用程序并且在使用Flask-Mail时遇到了问题。以下是相关的片段。我可以从命令行运行它们，它们正是我正在寻找的，但是当我将它们推送到Heroku时，我在页面上出现“内部服务错误”，并在日志中出现SMTP错误。
app.config.update(dict(
DEBUG = True,
MAIL_SERVER = 'smtp.gmail.com',
MAIL_PORT = 465,
MAIL_USE_TLS = False,
MAIL_USE_SSL = True,
MAIL_USERNAME = 'email@address.com'
MAIL_PASSWORD = 'password',
))
mail = Mail(app)
@app.route('/test1')
def test1():
msg = Message(
'Hello',
sender = 'email@address.com',
recipients = ['email@address.com'])
msg.body = "This is the email body"
msg.html = '<b>HTML</b> body'
with app.app_context():
mail.send(msg)
return "Sent"
