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

$oReq = ObjCreate("Chilkat.HttpRequest")
$oReq.HttpVerb = "POST"
$oReq.ContentType = "multipart/form-data"
$oReq.Path = "/xyz/something"

$oReq.AddParam "param1","value1"
$oReq.AddParam "param2","value2"

;  Add some small files to the request. (Small so we can see what the full request looks like without too much data..)
$oBd = ObjCreate("Chilkat.BinData")
$bSuccess = $oBd.LoadFile("qa_data/jpg/starfish20.jpg")
$oReq.AddBdForUpload("starfish20","starfish20.jpg",$oBd,"image/jpeg")

$bSuccess = $oBd.LoadFile("qa_data/pdf/helloWorld.pdf")
$oReq.AddBdForUpload("helloWorld","helloWorld.pdf",$oBd,"application/pdf")

$bSuccess = $oBd.LoadFile("qa_data/xml/tinyA.xml")
$oReq.AddBdForUpload("tinyA","tinyA.xml",$oBd,"text/xml")

;  This HTTP request contains binary data, so we cannot call GenerateRequestText
;  to examine it as a string.  We can instead call GenerateRequestFile
;  to write the request to a file and then examine using a hex editor,
;  or an editor that is capable of handling null bytes and non-printable chars (perhaps by displaying "?" chars instead).
