Question

我只想在python中发送带附件的电子邮件

import smtplib, os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders

def send_mail(send_from, send_to, subject, text, files=[], server="localhost"):
    assert type(send_to)==list
    assert type(files)==list

    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    msg.attach( MIMEText(text) )

    for f in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
        msg.attach(part)

    smtp = smtplib.SMTP('smtp.gmail.com:587')
    smtp.login('fu@gmail.com','fu')
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.close()

ATTACHMENTS = ['/tmp/2013-11-04-test.csv']
send_from=['fu@gmail.com']
send_to=['fu@gmail.com']
subject='adfadfadf'
text = 'adfadfadf'
send_mail(send_from, send_to, subject, text, files=ATTACHMENTS)

我如何授权？我必须提供用户名和密码。怎么样？

    smtp.login('fu@gmail.com','fu')
  File "/usr/lib/python2.7/smtplib.py", line 576, in login
    raise SMTPException("SMTP AUTH extension not supported by server.")
smtplib.SMTPException: SMTP AUTH extension not supported by server.

Answer 1

登录前需要致电starttls()：

smtp = smtplib.SMTP('smtp.gmail.com:587')
smtp.starttls()
smtp.login('fu@gmail.com', 'fu')

此外，您的send_from应该是str，而不是list：

send_from='fu@gmail.com'

请注意smtp.starttls()隐式调用smtp.ehlo()：

如果此会话没有先前的EHLO或HELO命令，则此方法首先尝试ESMTP EHLO。 https://docs.python.org/2/library/smtplib.html#smtplib.SMTP.starttls

Answer 2

在Gmail上，您还必须在smtp.ehlo()之前提供smtp.starttls() 这也是How to send an email with Gmail as provider using Python?

无法使用gmail通过python发送电子邮件 - smtplib.SMTPException：服务器不支持SMTP AUTH扩展
