Load JSON Object from HTTP Response Body

Demonstrates how to load the HTTP response body directly into a JSON object. PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Http
oleobject loo_Resp
oleobject loo_Json

li_Success = 0

loo_Http = create oleobject
li_rc = loo_Http.ConnectToNewObject("Chilkat.Http")
if li_rc < 0 then
    destroy loo_Http
    MessageBox("Error","Connecting to COM object failed")
    return
end if

loo_Resp = create oleobject
li_rc = loo_Resp.ConnectToNewObject("Chilkat.HttpResponse")

li_Success = loo_Http.HttpStr("GET","https://www.chilkatsoft.com/exampledata/sample.json","","","",loo_Resp)
if li_Success = 0 then
    Write-Debug loo_Http.LastErrorText
    destroy loo_Http
    destroy loo_Resp
    return
end if

// A JSON object is JSON that begins with "{" and ends with "}"
loo_Json = create oleobject
li_rc = loo_Json.ConnectToNewObject("Chilkat.JsonObject")

// If we wish to transfer (instead of copy) the JSON from the HttpResponse to the JsonObject, then add the keyword "TakeResponseBody" to UncommonOptions
// This could save memory for extremely large JSON responses.
loo_Resp.UncommonOptions = "TakeResponseBody"

loo_Resp.GetBodyJson(loo_Json)

loo_Json.EmitCompact = 0
Write-Debug loo_Json.Emit()

// Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
Write-Debug "----"
Write-Debug loo_Resp.BodyStr
