(VBScript) Load JSON Array from HTTP Response Body

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

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJarr 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 JsonArray by calling JsonArray.LoadSb.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

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

' resp is a Chilkat.HttpResponse
Set resp = http.PText("GET","https://www.chilkatsoft.com/exampledata/sampleArray.json","","","",0,0)

    outFile.WriteLine(http.LastErrorText)

' A JSON array is JSON that begins with "[" and ends with "]"
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonArray")
set jarr = CreateObject("Chilkat.JsonArray")

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

success = resp.GetBodyJarr(jarr)

outFile.WriteLine(jarr.Emit())

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


outFile.Close
