Question

我有多个文件是预定义路径的一部分，我正在尝试为每个可用的txt文件生成一封电子邮件。下面的代码适用一次，但每封电子邮件每个文件都会增加。

您的输入/建议会非常有用。谢谢， AL

# Import smtplib for the actual sending function

# Import the email modules we'll need

# Create a text/plain message
msg=email.mime.Multipart.MIMEMultipart()
#msg['Subject'] = '

msg['To'] = 'user1@domain.com'

# The main body is just another attachment
# body = email.mime.Text.MIMEText("""Email message body (if any) goes     here!""")
# msg.attach(body)


#To check if the directory is empty.
#If directory is empty program exits and no email/file copy operations are carried out
if os.listdir(sourceFolder) ==[]:
   print "No attachment today"
else:

       for iFiles in glob.glob('*.txt'):
      print (iFiles)
  print "The current location of the file is " +(iFiles)

  part = MIMEApplication(open(iFiles).read())
  part.add_header('Content-Disposition',
          'attachment; filename="%s"' % os.path.basename(iFiles))
  shutil.move(iFiles, destinationFolder)
  msg.attach(part)
  #shutil.move(iFiles, destinationFolder)
  #Mail trigger module
  server = smtplib.SMTP('IP:25')
  server.sendmail('john@domain.com',['user1@domain.com'], msg.as_string())
  server.quit()
  print "Email successfully sent!"
  print "Files moved successfully"

print "done"

这个问题出现在这里：

msg.attach(part)

您在做什么是一个接一个地连接部件，而不清洁以前连接的部件。

您应丢弃以前连接的部件，或重新初始化msg。在实践中，重新初始化msg更容易。

# ... code before

msg=email.mime.Multipart.MIMEMultipart()
#msg['Subject'] = '
msg['From'] = 'john@domain.com'
msg['To'] = 'user1@domain.com'

part = MIMEApplication(open(iFiles).read())
part.add_header('Content-Disposition',
                'attachment; filename="%s"' % os.path.basename(iFiles))
shutil.move(iFiles, destinationFolder)

# ... code after

在python中为每个txt文件发送附件电子邮件
