18.6. mimetools — Tools for parsing MIME messages

버전 2.3부터 폐지: The email package should be used in preference to the mimetools module. This module is present only to maintain backward compatibility, and it has been removed in 3.x.

This module defines a subclass of the rfc822 module’s Message class and a number of utility functions that are useful for the manipulation for MIME multipart or encoded message.

It defines the following items:

class mimetools.Message(fp[, seekable])

Return a new instance of the Message class. This is a subclass of the rfc822.Message class, with some additional methods (see below). The seekable argument has the same meaning as for rfc822.Message.

mimetools.choose_boundary()

Return a unique string that has a high likelihood of being usable as a part boundary. The string has the form 'hostipaddr.uid.pid.timestamp.random'.

mimetools.decode(input, output, encoding)

Read data encoded using the allowed MIME encoding from open file object input and write the decoded data to open file object output. Valid values for encoding include 'base64', 'quoted-printable', 'uuencode', 'x-uuencode', 'uue', 'x-uue', '7bit', and '8bit'. Decoding messages encoded in '7bit' or '8bit' has no effect. The input is simply copied to the output.

mimetools.encode(input, output, encoding)

Read data from open file object input and write it encoded using the allowed MIME encoding to open file object output. Valid values for encoding are the same as for decode().

mimetools.copyliteral(input, output)

Read lines from open file input until EOF and write them to open file output.

mimetools.copybinary(input, output)

Read blocks until EOF from open file input and write them to open file output. The block size is currently fixed at 8192.

18.6.1. Additional Methods of Message Objects

The Message class defines the following methods in addition to the rfc822.Message methods:

Message.getplist()

Return the parameter list of the Content-Type header. This is a list of strings. For parameters of the form key=value, key is converted to lower case but value is not. For example, if the message contains the header Content-type: text/html; spam=1; Spam=2; Spam then getplist() will return the Python list ['spam=1', 'spam=2', 'Spam'].

Message.getparam(name)

Return the value of the first parameter (as returned by getplist()) of the form name=value for the given name. If value is surrounded by quotes of the form 〈<…>〉 or 〈"…"〉, these are removed.

Message.getencoding()

Return the encoding specified in the Content-Transfer-Encoding message header. If no such header exists, return '7bit'. The encoding is converted to lower case.

Message.gettype()

Return the message type (of the form type/subtype) as specified in the Content-Type header. If no such header exists, return 'text/plain'. The type is converted to lower case.

Message.getmaintype()

Return the main type as specified in the Content-Type header. If no such header exists, return 'text'. The main type is converted to lower case.

Message.getsubtype()

Return the subtype as specified in the Content-Type header. If no such header exists, return 'plain'. The subtype is converted to lower case.
