如何在Python中压缩文件夹并通过电子邮件发送压缩文件？

Question

我想压缩一个文件夹及其所有子文件夹/文件,并将zip文件作为附件发送电子邮件.用Python实现这一目标的最佳方法是什么？

Answer 1

您可以使用zipfile模块使用zip标准来压缩文件,使用电子邮件模块来创建带附件的电子邮件,使用smtplib模块来发送它 - 所有这些都只使用标准库.

Python - 包括电池

如果您不喜欢编程而宁愿在stackoverflow.org上提问,或者(如评论中所建议的那样)不在homework标签上,那么,这里是:

import smtplib
import zipfile
import tempfile
from email import encoders
from email.message import Message
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart    

def send_file_zipped(the_file, recipients, sender='you@you.com'):
    zf = tempfile.TemporaryFile(prefix='mail', suffix='.zip')
    zip = zipfile.ZipFile(zf, 'w')
    zip.write(the_file)
    zip.close()
    zf.seek(0)

    # Create the message
    themsg = MIMEMultipart()
    themsg['Subject'] = 'File %s' % the_file
    themsg['To'] = ', '.join(recipients)
    themsg['From'] = sender
    themsg.preamble = 'I am not using a MIME-aware mail reader.\n'
    msg = MIMEBase('application', 'zip')
    msg.set_payload(zf.read())
    encoders.encode_base64(msg)
    msg.add_header('Content-Disposition', 'attachment', 
                   filename=the_file + '.zip')
    themsg.attach(msg)
    themsg = themsg.as_string()

    # send the message
    smtp = smtplib.SMTP()
    smtp.connect()
    smtp.sendmail(sender, recipients, themsg)
    smtp.close()

    """
    # alternative to the above 4 lines if you're using gmail
    server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
    server.login("username", "password")
    server.sendmail(sender,recipients,themsg)
    server.quit()
    """

使用此功能,您可以:

send_file_zipped('result.txt', ['me@me.org'])

别客气.
