Flask Security的Flask Mail注册从smtp.gmail.com

Question

我有一个使用Flask-Security注册的烧瓶应用程序，在注册时发送Flask Mail。我已经使用SSL在smtp.gmail.com端口464指出了烧瓶邮件配置。但是，当应用程序尝试发送邮件时，它会获得smtplib.SMTPAuthenticationError。如果我转到google admin page并允许＆＃34;不太安全的应用＆＃34;通过那时发送工作。

以下是发送失败并出现上述错误时收到的堆栈跟踪：

我的邮件配置是：

app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_SSL'] = True

当我转到谷歌管理员为我的应用启用TLS时会发生这种情况：

告诉Flask Mail遵守Google的安全标准，我该怎么办？

Answer 1

这是因为Google希望您的应用程序使用OAuth2。

  

为了更好地保护您的用户，我们建议您升级所有用户   应用程序到OAuth 2.0。如果您选择不这样做，您的用户将会这样做   被要求采取额外的步骤，以便继续访问你的   应用

如果您想使用Flask-Mail通过smtp发送电子邮件，则需要采取额外步骤并启用＆＃34;安全性较低的应用程序＆＃34;在您的Google管理页面中。

Answer 2

您可以使用google smtp服务器发送电子邮件，只需要一个可以从这里获得的应用专用密码： https://security.google.com/settings/security/apppasswords

在上面的页面上选择其他应用并为其输入名称，然后您将获得一个应用密码。

此应用正常运行并发送电子邮件：

# Try to send a mail using

from flask import Flask
from flask.ext.mail import Mail
from flask.ext.mail import Message


app = Flask(__name__)


app.config['MAIL_SERVER'] = 'smtp.googlemail.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USE_TLS'] = True
app.config['MAIL_USERNAME'] = "your gmail username"
app.config['MAIL_PASSWORD'] = "Your app spesfic password"
app.config['MAIL_DEFAULT_SENDER'] = 'Default sender name'

mail = Mail(app)

@app.route('/')
def hello_world():
    return 'Hello World!'

@app.route('/send')
def send_mail():
    msg = Message("Hello",
                  sender="test@test.com",
                  recipients=["test@test.com"])
    mail.send(msg)
    return ""

if __name__ == '__main__':
    app.run(debug=True)
