Get the text body content of a MIME part.

Explains and demonstrates the GetBodyEncoded and GetBodyDecoded methods. This example uses the MIME test data located at http://www.chilkatsoft.com/testData/sampleMime1.txt

The sampleMime1.txt contains:

Content-Type: multipart/mixed;
 boundary="------------070404010201060604000708"

This is a multi-part message in MIME format.

Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8"

#  The sampleMime1.txt is a MIME document with a top-level
#  multipart/mixed containing 3 sub-parts, each of which has the
#  same body text but with different content-transfer-encodings and
#  using different character encodings (utf-8 and iso-8859-1).

#  Calling mime.GetBodyEncoded or mime.GetBodyDecoded on the
#  top-level multipart/mixed MIME object will return an empty string.
#  It is because the "body" of a multipart MIME object is always empty.
#  A multipart MIME object contains sub-parts (each a MIME object),
#  and it is only the leaf-objects that can have non-empty bodies.

#  Get GetBodyDecoded method returns the body text decoded
#  from whatever the content-transfer-encoding may be, and
#  converted from whatever charset encoding might be used.
#  In this case, calling GetBodyDecoded on each of the three
#  sub-parts will return the same string.
#  To demonstrate:

# part1 is a CkMime
part1 = mime.GetPart(0)
print part1.getBodyDecoded() + "\n";

# part2 is a CkMime
part2 = mime.GetPart(1)
print part2.getBodyDecoded() + "\n";

# part3 is a CkMime
part3 = mime.GetPart(2)
print part3.getBodyDecoded() + "\n";

#  The GetBodyEncoded method will NOT decode from
#  whatever content-transfer-encoding is used.  However, it will
#  convert from whatever internal character encoding
#  may be used to return a string appropriate for the calling
#  programming language (for example, in .NET or any language
#  using ActiveX, all strings are Unicode..)
print part1.getBodyEncoded() + "\n";
print part2.getBodyEncoded() + "\n";
print part3.getBodyEncoded() + "\n";
