Lua Requires Chilkat v11.0.0+

Get the text body content of a MIME part.

See more MIME Examples

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";

Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local mime = chilkat.Mime.new()

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

local success = mime:load_mime_file("sampleMime1.txt")
if not success then
    print(mime.last_error_text)
    return
end

-- 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:
local part1 = chilkat.Mime.new()
success = mime:part_at(0, part1)
if not success then
    print(mime.last_error_text)
    return
end

print(part1:get_body_decoded())

local part2 = chilkat.Mime.new()
success = mime:part_at(1, part2)
if not success then
    print(mime.last_error_text)
    return
end

print(part2:get_body_decoded())

local part3 = chilkat.Mime.new()
success = mime:part_at(2, part3)
if not success then
    print(mime.last_error_text)
    return
end

print(part3:get_body_decoded())

-- 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..)
