Отправка сообщения Gmail

Question

я пытаюсь отправить сообщение Gmail со следующим кодом:

from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import base64
def create_message(sender, to, subject, message_text):
    """Create a message for an email.

    Args:
        sender: Email address of the sender.
        to: Email address of the receiver.
        subject: The subject of the email message.
        message_text: The text of the email message.

    Returns:
        An object containing a base64url encoded email object.
    """
    message = MIMEText(message_text)
    message['to'] = to
    message['from'] = sender
    message['subject'] = subject
    #return {'raw': base64.urlsafe_b64encode(message.as_string())}
    b64_bytes = base64.urlsafe_b64encode(message.as_bytes())
    b64_string = b64_bytes.decode()
    #body = {'raw': b64_string}
    return {'raw': b64_string}


s = "email"
t = "email"
sub = "test subject"
m = "message test"

create_message(s,t,sub,m)

, где s = мое электронное письмо (в данном примере заменено на «email», а t = другое мое электронное письмо (снова заменено)) не выдает никаких ошибок, но не отправляет сообщение. Также этот код не работал: #return {'raw': base64.urlsafe_b64encode(message.as_string())}, поскольку он выдал следующую ошибку: TypeError: a bytes-like object is required, not 'str' «Я решил это» с этим:

b64_bytes = base64.urlsafe_b64encode(message.as_bytes())
 b64_string = b64_bytes.decode()
 #body = {'raw': b64_string}
 return {'raw': b64_string}

edit (1): У меня есть учетные данные. json и передал пример API Google

Answer 1

Необходимо создать client_secret. json и вставить туда мои учетные данные, ctrc + c, ctrl + v старый пример и обновить его до python 3.x, решена проблема base 64, и она работает:)
