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. Swift

func chilkatTest() {

    // 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_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">
