HTTPService: What is its send method doing? - actionscript-3

Question

I've got a JSON string:
query = {"action":"do","password":"c","name":"s"}
When using HTTPService's send method:
_service = new HTTPService();
_service.url = "http://localhost:8080";
_service.method = "POST";
_service.contentType = "application/json";
_service.resultFormat = "text";
_service.useProxy = false;
_service.makeObjectsBindable = true;
_service.addEventListener(FaultEvent.FAULT,faultRX);
_service.addEventListener(ResultEvent.RESULT,resultRX);
_service.showBusyCursor = true;
var _request:Object = new Object();
_request.query = query;
_service.request = _request;
_service.send();
I don't know what I am doing wrong but on my HTTP server I get:
{["object","Object"]}
Any clues please?
Thanks

Answer 1

You are declaring an object of an object.
Try:
_service.request = query;
_service.send();

Answer 2

you get
{["object","Object"]}
because of this
var _request:Object = new Object();
_request.query = query;
_service.request = _request;
do this
var jsonOBJ:Object = {};
jsonOBJ.action = "do";
jsonOBJ.password = "c";
jsonOBJ.name = "s";
var _service:HTTPService = new HTTPService();
_service.url = "http://localhost:8080";
_service.method = "POST";
_service.contentType = "application/json";
_service.resultFormat = "text";
_service.useProxy = false;
_service.makeObjectsBindable = true;
_service.addEventListener(FaultEvent.FAULT,faultRX);
_service.addEventListener(ResultEvent.RESULT,resultRX);
_service.showBusyCursor = true;
_service.send( JSON.encode( jsonOBJ ) );// encode the json object with AS3Corelib
Don't forget top JSON decode the string on the server side.
