Javascript :: Facebook Flash App Cannot Communicate
Nov 27, 2010
My index.php file loads the Facebook JavaScript SDK and the FBJS bridge:[code]When I run this file on my server, I can communicate with Facebooks JavaScript SDK either indirectly through ExternalInterface calls, launching various Facebook UI dialogs etc. And I can also use the facebook-actionscript-api to launch the same dialogs directly from ActionScript.When I however use this index file as my Facebook canvas url and load the swf in a Facebook iFrame, the communication crashes the application. I'm not sure how to debug this but I think it might have to do with crossdomain security. Any ideas on debugging and/or solutions are welcome.

I'm trying to determine the practical difference between using the com.facebook.session.WebSession and com.facebook.session.JSSession. The documentation ([URL]) has more around WebSession - but the example I have which is closest to what solution I'm trying to implement uses JSSession and it looks like I could avoid all of the JavaScript pass-through & ExternalInterface calls I'm making. It appears that the benefit of using this new ActionScript Facebook API is to avoid having to make all of the Facebook calls via JavaScript.

What's an easy and secure way to let my Flash app communicate with my back-end server?
The Flash app, which is a video player, should retrieve the person's username and send back an ID. How would I do this?
Note: Back-end is written in Javascript.

for some reason, whenever I dynamically load a swf on a $(document).ready() by writing to a div, I am unable to make javascript calls to the browser. Specifically, all calls to the browser return "null". This does not occur when embedding the swf normally on the page load, but I would like to prevent loading of the swf until a specified point in time.
What the heck is going on here? Is there something special about dynamically embedding a swf that prevents the swf from talking to the browser? The methods ARE called (I've proven such by showing alerts), but all return values to any function, regardless of type returned, shows as null when it gets to flash.

I want to have my overlay adjust in size depending on how much content is being shown in the flash movie. Also, I want it to resize in real time when the user adjusts the content.

I'm working on a site that allows administrators to upload arbitrary SWFs and embed them on the page. Administrators are in theory trusted, but I still want to protect against potentially malicious administrators or misguided administrators from harming the site.
A part of the functionality of the site is that the SWFs can communicate to the containing browser page when it's finished and for the page to react.
Now, I can think of two ways to do this:
Use ExternalInterface.addCallback to create a global callback named something like isComplete that does logic and returns true or false depending on whether the Flash app is in a completed state. Then, just do something like setTimeout to just call that function repeatedly. I don't think this would require me to open up allowscriptaccess to the movie. Embed the movie with allowscriptaccess and have the movie call something like ExternalInterface.call('done') when it's finished. This option seems like it requires me to open up allowscriptaccess, which is a potential threat since I can't control the SWFs that would be embedded with this directive.

Has anyone successfully included the facebook fanbox in a flash website? I just do basic stuff on the side and I have created a flash website for my buddys company. He wants to incorporate the facebook fanbox into one of the pages. Facebook has a code generator that outputs something like this:
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script>
<script type="text/javascript">FB.init("API_KEY", "");</script>
<fb:fan profile_id="YOUR_PAGE_ID" stream="1" connections="10" width="300"></fb:fan>
<div style="font-size:8px; padding-left:10px"><a href="VANITY_URL">PAGE_NAME</a> on Facebook</div>
Is there a way to incorporate this into flash? The other option they have is iFrames. I have never heard of this, but it looks like this:

I have a SWF file that calls some javascript which shows the facebook login dialog via the javascript sdk.this all works fine, except for that fact that pop-up blockers block the login dialog, as it isnt invoked from a user action, but from flash.

The communicate between javascript and flex, but only if you are using an external HTML file in a browser, and not in a windowed app.

I'm playing a flash game on facebook. I know I can decompile it to find out all the commands and would like to make scripts to automate the game by calling procedures in the actionscript of the game. So I guess I would like to make a plugin also that would insert this console into any flash app and this would be handy for a lot of things. Then if anyone wants to hack a new game, u just decompile it and make a handbook of methods for people to make scripts with. So how would I go about making this console? I don't know if I could make a swf interact with the game or if it has to be compiled into the game's swf. Or if it is easier with javascript, that is cool too. maybe we can make a javascript library just for this. anyone can tell me more?

I'm currently building an application using the Adobe Facebook API and I've run into an issue where for the login method the Facebook login popup displays but when doing a Facebook share/post the popup is blocked.
This code works fine and displays me a Facebook login popup without question (Firefox):
var permissions:Array = ['publish_stream'];
Facebook.login( onFacebookLogin, { perms:permissions.join(',') } );
However, the following code running in the same application throws up a popup blocker (again Firefox):
Facebook.ui( "stream.publish", "popup", params );
Does anyone know of a work around this issue to make the share popup come up just like the login popup?

In Flash Player 10.1 and later, the ScriptBridge class provides another way to communicate from JavaScript running in a browser to ActionScript (but not from ActionScript to JavaScript). The ScriptBridge class offers significantly better performance than the ExternalInterface class, and provides access to the entire ActionScript 3.0 API from JavaScript. By contrast, the ExternalInterface class provides access only to callback functions in ActionScript.If you need to call JavaScript from ActionScript, or need to communicate between ActionScript and any other programming language
you must use the ExternalInterface API. If you need to call ActionScript from JavaScript, the ScriptBridge class is recommended. The rest of the section describes the ExternalInterface class.my research makes me believe that this new Flash Player plugin API is most likely resulting from implementing recent changes in the Netscape Plugin API. Hopefully it should be as simple as having the player script NPObject properties and functions to use to access objects, packages and classes of the flash application.

Im having a little problem making javascript communicate with actionScript, Here is the problem, i have a application that uses javascript to communicate with SWF and pass it some values, and the code was working in AS2 with the following:
[Code]....
in this example the aplication would pass key to the javascrip function and the function would put the value in the swf variable called _root.valor. So the problem is (as you already know) _root has gone in AS3. And every thing i tryed so far seems not to work. every thing i read so far was to embeb the swf in the js and use
root.loaderInfo.parameters.valor, well i dont want to use the embedSWF because i need to get the activeX cotnrol from my document. Is there any _root replacement? is anyway to get this to work at all ?

I've been messing around a bit with a Facebook application for a while now, which is using FBML. A need has arisen to integrate graphs to display data. From what I can tell my options would be one of the following:
Find a Flash Graph that doesn't require a JavaScript library to work Convert the application to an IFrame application, and hope that Facebook wont break the Graph JavaScript Generate the graph serverside with GD or ImageMagick I would preferably not go with option 3, due to how boring generated graphs look, and serverside load.
Does anyone have any opinions or suggestions on how I would best solve this?

I'm trying to upload a photo on Facebook using Javascript SDK. In particular I generate a base64 encoded bytearray from my Actionscript3 app, I pass it to Javascript file using ExternalInterface, and from that I decode the bytearray and I try to upload to FB. But it give me this error:
{"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}
I tried to upload an image simply from url, and in that way it goes well! This is my Javascript code:
upPhoto:function(photo) {
var img = F.decode_base64(photo);
FB.api('/me/photos', 'post', {
message:'test',
fileName:'test',

How do I add a widget to Facebook wall? So when a user clicks on wall post, it gets opened there only, like YouTube video/audio.
It's certainly possible, as Slideshare app [URL] does it.
And, I see that it's a Flash component. I have an iframe (Javascript/html) widget.

I'm having a hard time understanding the logic here.... What is the difference between the facebook session returned from the javascript api as opposed to the one retrieved from AS3 Facebook api when your application is in facebook. I ask this because When I login via invoked via pure javascript or already logged in the permissions are sent to me as well however AS3's FacebookSession.availablePermissions continues to be an empty array Login invoked via flash will however return the availablePermissions Whats the difference in login invocations?

We've just developed a small Facebook puzzle that people win some gifts from our customer. I'd like to ask a few questions since I'm pretty stuck despite tried lots of things. First I'd like to write what we have and then will explain our problems.oot of application (/) checks for signed_request in POST params, extracts information from it to see if we've registered the logged in user into our database. This checks are also used to understand if the request is sent from Facebook or not to prevent requests coming outside of Facebook. (will write why we want this)Once the application is successfully rendered, Facebook JS API takes place, does its checks and sets the fbsr cookie. We use that cookie information while processing ajax requests to check if the request really belongs to the logged in user (e.g.: scores being sent for a user belong to the logged in user).
We implemented CSRF protection and another protection to check if the requests are POST and more specifically AJAX requests and return 40x if not.nd out that some people seem to take advantage of this bug.One way I thought of is to ignore all requests except coming from Facebook. Since the ajax requests are blocked (cross site) we should have been safe. However this leaded to another problem that, once we redirect users to e.g. leaderboard the signed_request data is lost and our index page returns 40x once the user tries to go back since our application thinks that the user tries to visit our application outside of Facebook.

I'm writing an Adobe AIR app using plain HTML which needs to upload photos to Facebook. I don't think Facebook's JavaScript/Connect library includes photo uploading functionality, but their ActionScript library does. However, I'm having trouble loading the ActionScript library into the HTML page.
Adobe's documentation describes the process of loading ActionScript libraries into HTML AIR apps, which I tried using the compiled Flash library available here (specifically, Facebook_library_with_AIRConnect_v3.4_flash.swc). So my page looks something like:
<html>
<head>
<title>Hello World</title>
[code]....
Is the compiled library file I used the wrong one (do I need a .swf instead of a .swc)?If so, do I need to create my own compiled library somehow from the ActionScript source?Is the namespace I'm using incorrect? (in addition to com.facebook.Facebook() I tried .Facebook(), .fb.Facebook(), .facebook.Facebook(), etc)Should I just give up and try to learn Flex instead?
