[xiaix]

function testMe()
{
       var r = new sn_ws.RESTMessageV2('test', 'get');
       console.debug("r: " + r);
       var response = r.execute();
       console.debug("response: " + response); 
       var responseBody = response.getBody();
       console.debug("responseBody: " + responseBody);
       var httpStatus = response.getStatusCode();
       console.debug("httpStatus: " + httpStatus);
}
