(Visual FoxPro) 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

loResp = loHttp.PText("GET","https://www.chilkatsoft.com/exampledata/sample.json","","","",0,0)

* 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')
loJson = 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.
loResp.UncommonOptions = "TakeResponseBody"

loResp.GetBodyJson(loJson)

loJson.EmitCompact = 0
? loJson.Emit()

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

RELEASE loResp

RELEASE loHttp
