如何发送电子邮件附件？ [英] How to send email attachments?

问题描述

我有理解如何使用Python发送附件的问题。我已经使用 smtplib 成功发送了简单的邮件。有人可以解释如何在电子邮件中发送附件。我知道网上还有其他帖子，但作为一个Python初学者，我觉得他们很难理解。

I am having problems understanding how to email an attachment using Python. I have successfully emailed simple messages with the smtplib. Could someone please explain how to send an attachment in an email. I know there are other posts online but as a Python beginner I find them hard to understand.

推荐答案

这是另一个改编自这里：

import smtplib
from os.path import basename
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.utils import COMMASPACE, formatdate


def send_mail(send_from, send_to, subject, text, files=None,
              server="127.0.0.1"):
    assert isinstance(send_to, 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 or []:
        with open(f, "rb") as fil:
            part = MIMEApplication(
                fil.read(),
                Name=basename(f)
            )
            part['Content-Disposition'] = 'attachment; filename="%s"' % basename(f)
            msg.attach(part)


    smtp = smtplib.SMTP(server)
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.close()

与第一个例子相同...但是应该更容易放入。

It's much the same as the first example... But it should be easier to drop in.
