Python发送以整个文件夹的内容为附件的邮件的教程

由于我经常需要备份文件夹下的内容到邮件里面，每个打开邮件，上传文件，发送，太过麻烦，其实每次发送的文件都是放在固定 置的，只是邮件标题不同而已，于是用 python 为自己写了个发送文件到邮箱的小工具，在任意目录下执行该脚本，并指定邮件标 ，就将指定文件夹下的文件发送到邮箱中备份起来 。

#!/usr/bin/env python
# coding: utf-8

from smtplib import SMTP,quotedata,CRLF,SMTPDataError
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase

from email import Encoders
from sys import stderr,stdout

class ExtendedSMTP(SMTP):
  def data(self,msg):
    self.putcmd("data")
    (code,repl)=self.getreply()
    if self.debuglevel > 0 : print >> stderr,"data:",(code,repl)
    if code != 354:
      raise SMTPDataError(code,repl)
    else:
      q = quotedata(msg)
      if q[-2:] != CRLF:
        q = q + CRLF
      q = q + "." + CRLF

      # begin modified send code
      chunk_size = 2048
      bytes_sent = 0

      while bytes_sent != len(q):
        chunk = q[bytes_sent:bytes_sent+chunk_size]
        self.send(chunk)
        bytes_sent += len(chunk)
        if hasattr(self,"callback"):
          self.callback(bytes_sent,len(q))
      # end modified send code

      (code,msg)=self.getreply()
      if self.debuglevel >0 : print>>stderr,msg)
      return (code,msg)

def callback(progress,total):
  percent = 100. * progress / total
  stdout.write('\r')
  stdout.write("%s bytes sent of %s [%2.0f%%]" % (progress,total,percent))
  stdout.flush()
  if percent >= 100: stdout.write('\n')

def sendmail(subject):
  MAIL_FROM = '[e-mail]'
  MAIL_TO = ['[e-mail]']
  BAK_DIR = '/path/to/bak/folder'

  msg = MIMEMultipart()
  msg['From'] = MAIL_FROM
  msg['Subject'] = subject

  msg.attach( MIMEText('test send attachment') )
  for filename in os.listdir(BAK_DIR):
    part = MIMEBase('application',"octet-stream")
    part.set_payload(open(os.path.join(BAK_DIR,filename),"rb").read() )
    Encoders.encode_base64(part)
    part.add_header('Content-disposition','attachment; filename="%s"' % os.path.basename(filename))
    msg.attach(part)

  try:
    smtp = ExtendedSMTP()
    smtp.callback = callback
    smtp.connect('smtp.qq.com',25)
    smtp.login('mymail','mypwd')
    smtp.sendmail(MAIL_FROM,MAIL_TO,msg.as_string())
    smtp.close()
    os.system('rm -f %s/*' % BAK_DIR)
  except Exception,e:
    print e

if __name__ == '__main__':
  if len(sys.argv) == 1:
    print 'Please specific a subject'
    print 'Usage: send_files <MAIL_SUBJECT>'
  else:
    sendmail(sys.argv[1])

安装：

配置好收件人，发件人，smtp地址，用户名，密码及要发送文件所在的路径。

将文件保存为 send_files，保存到 /usr/bin 下面。

然后设置文件权限为可执行：

$ chmod +x send_files

用法：

$ send_files '邮件标题'
