  27. 27. Checking for Permissionsvar missingPermissions:Array = new Array();private function requestPermissionsInfo():void { var permissions:Array = new Array("read_stream", "publish_stream"); Facebook.fqlQuery("SELECT {0} FROM permissions WHERE uid = me() ", onFQLResponse, [permissions.toString()]);}private function onFQLResponse(success:Object, fail:Object):void { [{ missingPermissions = new Array(); "email":0, var results:Array = success as Array; "publish_stream":1, if (success && results) { "read_stream":1 for (var i:int = 0; i < results.length; i++) { }] var queryResult:Object = results[i]; for (var param:String in queryResult) { if (Boolean(queryResult[param]) == false) { missingPermissions.push(param); } } } }}
  28. 28. Creating & Modifying Data on Facebook
  29. 29. Posting data to the Graph APIvar options:Object = new Object();options.name = "I found a trophy";options.caption "100001986549853_202809986461885"} {"id": = "Gold trophy";options.description = "I found a Gold trophy while using ...";options.link = "http://apps.facebook.com/packt_facebook/";options.picture = "http://facebook.psyked.co.uk/packt/images/gold.png";Facebook.api("me/feed", responseHandler, options, "post");private function responseHandler(success:Object, fail:Object):void { if (success) { trace(JSON.encode(success, true)); } else { trace(JSON.encode(fail, true)); }}
  30. 30. Posting image data - webcamimport mx.graphics.ImageSnapshot;var options:Object = {};options.fileName = "webcam.png";options.image = ImageSnapshot.captureBitmapData(webcam_display);options.message = "Image caption";Facebook.api("me/photos", photoUploadComplete, options, "post");

Posting image data - FileReferencevar options:Object = {};options.fileName = fr.name;options.image = fr.data;var fileExtension:String = fr.name.split(".")[fr.name.split(".").length-1];switch (fileExtension) { case "gif": options.contentType = "image/gif"; break; case "png": options.contentType = "image/png"; break; case "jpeg": case "jpg": options.contentType = "image/jpeg"; break;}options.message = "Image caption";Facebook.api("me/photos", photoUploadComplete, options, "post");
  32. 32. Editing existing Objects• Editing objects (that can be edited) is done byvar options:Object = new Object(); making a POST request to an Objects’ URL.options.name = "I found a trophy";options.caption = "Gold trophy";options.description = "I found a Gold trophy while using ...";options.link = "http://apps.facebook.com/packt_facebook/";options.picture = "http://facebook.psyked.co.uk/packt/images/gold.png"; Application, Album, Event, Group and UserFacebook.api("me/feed", responseHandler, options, "post"); objects have properties that can be edited.private function responseHandler(success:Object, fail:Object):void { if (success) { trace(JSON.encode(success, true)); } else { trace(JSON.encode(fail, true)); }}
  33. 33. Deleting existing Objectsvar options:Object = new Object();options.method = "delete";Facebook.api("10150322337577749", responseHandler, options, "post");private function responseHandler(success:Object, fail:Object):void { if (success) { trace(JSON.encode(success, true)); } else { trace(JSON.encode(fail, true)); }}
