Answer 1

Alternatively if you're using Flash Player 11 or AIR 3.0 or higher you can use the built in JSON object to decode your JSON. It's a top level object so you dont even need to import anything, just do:

var decoded : Object = JSON.parse(loadedText);

See: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/JSON.html

Answer 2

I believe the as3corelib has a JSON serializer and deserializer

You can use those instead of re-inventing the wheel and writing parsing logic afresh.

Answer 3

1. Add the corelib.swc to your library path.

2. Import the JSON library: import com.adobe.serialization.json.JSON;

3. Call your service with code something like this:

   var request:URLRequest=new URLRequest();
   request.url=YOUR_ENDPOINT
   request.requestHeaders=[new URLRequestHeader("Content-Type", "application/json")];
   request.method=URLRequestMethod.GET;
   var loader:URLLoader=new URLLoader();
   loader.addEventListener(Event.COMPLETE, receive);
   loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, notAllowed);
   loader.addEventListener(IOErrorEvent.IO_ERROR, notFound);
   loader.load(request);
   
   protected function receive(event:Event):void
   {
        var myResults:Array=JSON.decode(event.target.data);
   }
   

4. Parse the results with JSON.decode(results).
