(Chilkat2-Python) 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.

--------------070404010201060604000708
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain; charset="utf-8";

# See Global Unlock Sample for sample code.

mime = chilkat2.Mime()

# Load the sampleMime1.txt file into the MIME object.
# (This file is available at http://www.chilkatsoft.com/testData/sampleMime1.txt )

# 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())

# part2 is a CkMime
part2 = mime.GetPart(1)
print(part2.GetBodyDecoded())

# part3 is a CkMime
part3 = mime.GetPart(2)
print(part3.GetBodyDecoded())

# 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())
print(part2.GetBodyEncoded())
print(part3.GetBodyEncoded())
