  1. Introduction to opensocial-actionscript-client Sung Wu Aaron Tong 2009/03/20

  2. Agenda • Intro • Architecture • Code-sample • Resource

  3. A Flex library for accessing OpenSocial API OpenSocial 0.81 AS3 Opensource http://code.google.com/p/opensocial-actionsctip-client Introduction

  4. Architecture OpenSocial Container Browser OpenSocial Gadget Dynamically Generated javascript Your swf Javascript API

  5. Design Decisions • Uses OpenSocial Javascript API instead of OpenSocial REST spec • Crossdomain.xml restrictions on some containers • REST not implemented yet on some containers • Dynamic Javascript injection • Simple deployment • Interface: follows OpenSocial Javascript API • Easy to understand if you come from the normal OpenSocial development world. Follows the standard.

  6. Initialization <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"> …. private function init():void { //create the Container container = Container.instance; container.setContainer(new StandardContainer()); }

  7. Code sample: update data private function updateData():void{    var dr:DataRequest = container.newDataRequest();    dr.add(dr.newUpdatePersonAppDataRequest("VIEWER", "testdatakey1", 'test'));    dr.send(updatePersonAppDataCallback);}private function updatePersonAppDataCallback(dataResp:DataResponse):void {    Alert.show("updatePersonAppDataCallback().  \n dataResp.hadError()=" + dataResp.hadError()               + "\n dataResp.getErrorMessage()=" + dataResp.getErrorMessage());}

  8. Code Sample: fetch data private function fetchData():void{    var dr:DataRequest = container.newDataRequest();    var idSpecParam:Object = {};    idSpecParam[com.nextgenapp.opensocial.IdSpec.Field.USER_ID] = "VIEWER";    var idSpec:IdSpec = container.newIdSpec(idSpecParam); dr.add(dr.newFetchPersonAppDataRequest(idSpec, ["testdatakey1"], null), opt_key);     dr.send(fetchPersonAppDataCallback); }private function fetchPersonAppDataCallback(dataResp:DataResponse):void {    if (dataResp.hadError()) {        Alert.show("error: " + dataResp.getErrorMessage());    }    var appData:Object = dataResp.get("data").getData();    Alert.show("appData=" + appData);    // appData should have a member (user's id).  inside that, it should have a member    var appDataDisplay:String = "";    for (var propNameLevel1:String in appData) {        appDataDisplay += ("\n" + propNameLevel1 + " : " + appData[propNameLevel1]);        for (var propNameLevel2:String in appData[propNameLevel1]) {            appDataDisplay += ("\n----" + propNameLevel2 + " : " + appData[propNameLevel1][propNameLevel2]);        }    }    Alert.show("appData expanded=" + appDataDisplay);}
