python-3.x - 发送 gmail 消息

Question

我正在尝试使用以下代码发送 gmail 消息：

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)

其中 s = 我的电子邮件（在此示例中替换为“电子邮件”，t = 我的其他电子邮件（再次替换））它不会排除任何错误，但不会发送消息。此代码也不起作用： #return {'raw': base64.urlsafe_b64encode(message.as_string())} 因为它产生了以下错误：TypeError: a bytes-like object is required, not 'str' “我解决了这个问题”：

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

编辑（1）：我确实有credentials.json并通过了google api示例

需要创建 client_secret.json 并将我的凭据粘贴到那里，ctrc+c，ctrl+v 一个旧示例并将其更新到 python 3.x，解决了 base 64 问题并且它可以工作:)
