(Lianja) 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.

loHttp = createobject("CkHttp")

loResp = loHttp.PText("GET","https://www.chilkatsoft.com/exampledata/sample.json","","","",.F.,.F.)
if (loHttp.LastMethodSuccess = .F.) then
    ? loHttp.LastErrorText
    release loHttp
    return
endif

// A JSON object is JSON that begins with "{" and ends with "}"
loJson = createobject("CkJsonObject")

// 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.
loResp.UncommonOptions = "TakeResponseBody"

loResp.GetBodyJson(loJson)

loJson.EmitCompact = .F.
? loJson.Emit()

// Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
? "----"
? loResp.BodyStr

release loResp
