(VBScript) 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.

Set fso = CreateObject("Scripting.FileSystemObject")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = CreateObject("Chilkat.Http")

' resp is a Chilkat.HttpResponse

' A JSON object is JSON that begins with "{" and ends with "}"
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = CreateObject("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.
resp.UncommonOptions = "TakeResponseBody"

success = resp.GetBodyJson(json)

json.EmitCompact = 0
outFile.WriteLine(json.Emit())

' Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
outFile.WriteLine("----")
outFile.WriteLine(resp.BodyStr)
