Send SOAP multipart/related with XML Body and Zip Attachment

See more REST Misc Examples

Demonstrates how to construct and send a multipart/related POST containing a SOAP XML body and a binary zip attachment. Lua

local chilkat = require("chilkat")

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

-- This example constructs and sends the following HTTP request.
-- (The boundary strings will be different and auto-generated by Chilkat)

-- Accept-Encoding: gzip,deflate
-- SOAPAction: invio
-- Content-Type: Multipart/Related; boundary="MIME_boundary"; type="text/xml"; start="mailto:rootpart@soapui.org"
-- MIME-Version: 1.0
--
-- --MIME_boundary
-- Content-Type: text/xml; charset=UTF-8
-- Content-Transfer-Encoding: 8bit
-- Content-ID: <rootpart@soapui.org>
--
-- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:attachment.ws.it">
-- <soapenv:Header/>
-- <soapenv:Body>
--   <urn:inputBean>
--    <nomeFileAllegato>myfile.zip</nomeFileAllegato>
--   </urn:inputBean>
-- </soapenv:Body>
-- </soapenv:Envelope>

-- --MIME_boundary
-- Content-Type: application/zip
-- Content-Transfer-Encoding: binary
-- Content-ID: <myfile.zip>
-- Content-Disposition: attachment; name="myfile.zip"; filename="myfile.zip"

-- ... binary zip data goes here ...
