Now that you know how to generate a message with alternatives and one with attachments, you may be
wondering how to do both. To do that, you create a standard multipart for the main message. Then you
create a multipart/alternative inside that for your body text, and attach your message formats to it.
Finally, you attach the various files. Take a look at mime_gen_both.py for the complete solution.
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email import utils, encoders
import mimetypes, sys
def genpart(data, contenttype):
maintype, subtype = contenttype.split('/')
if maintype == 'text':
retval = MIMEText(data, _subtype=subtype)
else:
retval = MIMEBase(maintype, subtype)
retval.set_payload(data)
encoders.encode_base64(retval)
return retval
def attachment(filename):
fd = open(filename, 'rb')
mimetype, mimeencoding = mimetypes.guess_type(filename)
if mimeencoding or (mimetype is None):
mimetype = 'application/octet-stream'
retval = genpart(fd.read(), mimetype)
retval.add_header('Content-Disposition', 'attachment',
filename = filename)
fd.close()
return retval
messagetext = """Hello,
This is a *great* test message from Chapter 12. I hope you enjoy it!
-- Anonymous"""
messagehtml = """Hello,<P>
This is a <B>great</B> test message <P>
-- <I>Anonymous</I>"""
msg = MIMEMultipart()
msg['To'] = '[email protected]'
msg['From'] = 'Test Sender <[email protected]>'
msg['Subject'] = 'Test Message'
msg['Date'] = utils.formatdate(localtime = 1)
msg['Message-ID'] = utils.make_msgid()
body = MIMEMultipart('alternative')
body.attach(genpart(messagetext, 'text/plain'))
body.attach(genpart(messagehtml, 'text/html'))
msg.attach(body)
for filename in sys.argv[1:]:
msg.attach(attachment(filename))
print msg.as_string()
