python - 在 Python smtplib 中附加一个 txt 文件

Question

我正在发送如下纯文本电子邮件:

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

def send_message():
    msg = MIMEMultipart('alternative')
    s = smtplib.SMTP('smtp.sendgrid.net', 587)
    s.login(USERNAME, PASSWORD)

    toEmail, fromEmail = to@email.com, from@email.com
    msg['Subject'] = 'subject'
    msg['From'] = fromEmail
    body = 'This is the message'

    content = MIMEText(body, 'plain')
    msg.attach(content)
    s.sendmail(fromEmail, toEmail, msg.as_string())

除了这条消息，我想附上一个 txt 文件，“log_file.txt”。如何在此处附加 txt 文件？

同样的方式，使用msg.attach:

from email.mime.text import MIMEText

filename = "text.txt"
f = file(filename)
attachment = MIMEText(f.read())
attachment.add_header('Content-Disposition', 'attachment', filename=filename)           
msg.attach(attachment)
