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. Rust

// 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 ...
// --MIME_boundary--
//

// by calling SetMultipartBodyStream.

// When debug mode is turned on, no request is actually sent.
