Append Part to MIME

See more MIME Examples

Demonstrates the AppendPart method for adding sub-parts to MIME. Lua

local chilkat = require("chilkat")

local success = false

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

-- Create a text/plain part.
local ptMime = chilkat.Mime.new()
ptMime:set_body_from_plain_text("This is the plain text body")
print(ptMime:get_mime())
print("****")

-- The ptMime contains:
-- ---------------------------------------
--     Content-Type: text/plain
--     Content-Transfer-Encoding: 7bit
--
--     This is the plain text body
-- ---------------------------------------

-- Start with an empty MIME object...
local topLevelMime = chilkat.Mime.new()

-- Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
topLevelMime:new_multipart_mixed()

-- Append the ptMime as a child.
topLevelMime:append_part(ptMime)
print(topLevelMime:get_mime())
print("****")

-- The topLevelMime contains:
-- --------------------------
--     Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
--
--     --------------010907090104040508040404
--     Content-Type: text/plain
--     Content-Transfer-Encoding: 7bit
--
--     This is the plain text body
--     --------------010907090104040508040404--
--

-- IMPORTANT: A copy of the MIME passed in AppendPart is appended.
-- Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
-- For example:
ptMime:set_body("this is the new plain text body.")
-- topLevelMime is unchanged.
print(topLevelMime:get_mime())
print("****")

-- To change the content in topLevelMime, we must get the text/plain part.
-- For example:

local ptMime2 = chilkat.Mime.new()
topLevelMime:part_at(0, ptMime2)

ptMime2:set_body("this is the new plain text body.")
-- Now topLevelMime is changed.
print(topLevelMime:get_mime())
