    NSLog(@"%@",http.LastErrorText);
    return;
}

// A JSON object is JSON that begins with "{" and ends with "}"
CkoJsonObject *json = [[CkoJsonObject alloc] init];

// 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";

[resp GetBodyJson: json];

json.EmitCompact = NO;
NSLog(@"%@",[json Emit]);

// Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
NSLog(@"%@",@"----");
NSLog(@"%@",resp.BodyStr);
