(PowerBuilder) Load JSON Object from HTTP Response Body

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

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJson method. Prior to v9.5.0.89, and application would need to first copy the HTTP response body to a Chilkat StringBuilder object by calling GetBodySb, and then load the JSON object by calling LoadSb.

// Use "Chilkat_9_5_0.JsonObject" for versions of Chilkat < 10.0.0
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)

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
