6.10 The multifile Module

The multifile module is a support module that allows you to treat each part of a multipart MIME message as an individual file, as shown in Example 6-14.

Example 6-14. Using the multifile Module

File: multifile-example-1.py

import multifile
import cgi, rfc822

infile = open("samples/sample.msg")

message = rfc822.Message(infile)

# print parsed header
for k, v in message.items():
    print k, "=", v

# use cgi support function to parse content-type header
type, params = cgi.parse_header(message["content-type"])

if type[:10] == "multipart/":

    # multipart message
    boundary = params["boundary"]

    file = multifile.MultiFile(infile)

    file.push(boundary)

    while file.next():

        submessage = rfc822.Message(file)

        # print submessage
        print "-" * 68
        for k, v in submessage.items():
            print k, "=", v
        print
        print file.read()

    file.pop()

else:

    # plain message
    print infile.read()
