具有基本身份验证的python aiosmtpd服务器

Question

我试图创建一个aiosmtpd服务器来处理接收到的电子邮件。它在没有身份验证的情况下工作得很好，但我只是不知道如何设置身份验证。我已经翻阅了这些文件，并寻找了关于这方面的例子。

关于我目前如何使用它的示例：

from aiosmtpd.controller import Controller

class CustomHandler:
    async def handle_DATA(self, server, session, envelope):
        peer = session.peer
        mail_from = envelope.mail_from
        rcpt_tos = envelope.rcpt_tos
        data = envelope.content         # type: bytes
        # Process message data...
        print('peer:' + str(peer))
        print('mail_from:' + str(mail_from))
        print('rcpt_tos:' + str(rcpt_tos))
        print('data:' + str(data))
        return '250 OK'

if __name__ == '__main__':
    handler = CustomHandler()
    controller = Controller(handler, hostname='192.168.8.125', port=10025)
    # Run the event loop in a separate thread.
    controller.start()
    # Wait for the user to press Return.
    input('SMTP server running. Press Return to stop server and exit.')
    controller.stop()```

which is the basic method from the documentation.

could someone please provide me with an example as to how to do simple authentication?

好的，因为您使用的是1.3.0版本，所以您可以按照认证文档进行操作。

一种快速的开始方法是在验证器回调指南之后创建一个“身份验证函数”(可以是处理程序类中的一个方法，也可以是独立的)。

一个简单的例子：

from aiosmtpd.smtp import AuthResult, LoginPassword

auth_db = {
    b"user1": b"password1",
    b"user2": b"password2",
    b"user3": b"password3",
}

# Name can actually be anything
def authenticator_func(server, session, envelope, mechanism, auth_data):
    # For this simple example, we'll ignore other parameters
    assert isinstance(auth_data, LoginPassword)
    username = auth_data.login
    password = auth_data.password
    # If we're using a set containing tuples of (username, password),
    # we can simply use `auth_data in auth_set`.
    # Or you can get fancy and use a full-fledged database to perform
    # a query :-)
    if auth_db.get(username) == password:
        return AuthResult(success=True)
    else:
        return AuthResult(success=False, handled=False)

然后创建控制器，如下所示：

    controller = Controller(
        handler,
        hostname='192.168.8.125',
        port=10025,
        authenticator=authenticator_func,  # i.e., the name of your authenticator function
        auth_required=True,  # Depending on your needs
    )
