Actionscript -> JSON -> PHP
Posted in Flex/ActionScript on December 23rd, 2009 by admin – Be the first to commentLately I have been using a tool a lot that I wrote some months ago, so I thought I better share it with the rest of the world. It’s a tool for sending and receiving Objects between a Flash/Flex client and a PHP server.
objectFromServer:
function objectFromServer(url:String, data:Object, handler:Function):void { var loader:URLLoader = new URLLoader(); var requester:URLRequest = new URLRequest(); requester.method = URLRequestMethod.POST; loader.addEventListener(Event.COMPLETE, function(event:Event):void { var tempLoader:URLLoader = URLLoader(event.target); var obj:Object = JSON.decode(tempLoader.data); handler(obj); }); loader.addEventListener(IOErrorEvent.IO_ERROR, function(event:IOErrorEvent):void { Alert.show("ioErrorHandler: " + event); }); loader.dataFormat = URLLoaderDataFormat.TEXT; requester.url = url; var variables:URLVariables = new URLVariables(); variables.json = JSON.encode(data); requester.data = variables; loader.load(requester); }
You will need to download as3corelib.swc from http://code.google.com/p/as3corelib/ and add it to your project’s libary path.
This is how you add it in Flex Builder: Properties->Flex Build Path->Libary path->Add SWC…
I have written a simple test program to show how objectFromServer is used.
ActionScript:
setInterval(function():void { objectFromServer("/tests/objectFromServer.php", {name: "Mikkel"}, function(o:Object):void { myLabel.text = o.text as String; }); }, 3000);
PHP:
<?php $o = json_decode($_POST["json"]); $result = array("text" => "Hello ".$o->name.", server time is " . time()); echo json_encode($result); ?>
