python - 属性错误 : MIMEText instance has no attribute 'encode'

Question

我正在尝试使用 smtplib 发送附件。但由于某些原因，我得到了这个回溯。任何帮助将非常感激。

#!/usr/bin/python

import smtplib
import getpass
from email import Encoders
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

fromaddr = "<email>"
toaddr = "<email>"

username = "email"
password = getpass.getpass("Email password : ")
filename = 'test.txt'
f = file(filename)
msg = MIMEMultipart()
attachment = MIMEText(f.read())
attachment.add_header('Content-Disposition','attachment',filename = filename)
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = 'Test'
msg.attach(MIMEText(attachment))
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.ehlo()
server.login(username,password)
server.sendmail(fromaddr,toaddr,msg.as_string())
server.quit()

错误:

Traceback (most recent call last):
  File "./emailte.py", line 21, in <module>

Your attachment is already a MIMEText object. So, why do that again in mag.attach()? Have you tried msg.attach(attachment)?
