I found an issue in my AS3 application. On my local machine everything is good, but when I sent it to my friend, he wasn't able to open it on his computer, because he got
Error #2044: Unhandled securityError:. text=Error #2048: Security
sandbox violation: cannot load data from data.json
The same error happens when I upload my application to web. I can't play it and get the same error.
Here is my code:
var myTextLoader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("data.json");
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
myTextLoader.load(request);
...
private function onLoaded(e:Event):void
{
var loader:URLLoader = URLLoader(e.target);
var myObject:Object = JSON.parse(loader.data);
}
How can I fix it? Please, help me if you can :)
Local SWFs cannot get local filesystem access.
Online SWFs can access resources according to the same origin policy, or further if a crossdomain.xml is set.
You cannot fix this for local, but online SWFs should be able to do this.
Try:
var request:URLRequest = new URLRequest("./data.json");
Which means if a SWF is hosted at:
https://www.example.com/foo/flash.swf
It can access:
https://www.example.com/foo/data.json

I'm using the flash debug player(version 16) and I'm trying to access a users photo from within flash as3. Firstly, the Security error i'm receiving, here it is.
SecurityError: Error #2122: Security sandbox violation: Loader.content: http s://graffiti-galore.herokuapp.com/fb/GraffitiGalore.swf?build=0001 cannot access http s://fbcdn-profile-a.akamaihd.net/hprofile-ak-xfp1/v/t1.0-1/c46.46.570.570/s50x50/398269_10152199084495525_2139734276_n.jpg?oh=29be37fd74f7d338a7b5c23b9aadd474&oe=5548F552&gda=1431395518_d142c304e8b8afa8df340e6cac093b29.

I'm using the free Heroku dino that is being offered and I'm simply doing a fetch call to the graph api users object. fetching the id,first_name, last_name,picture.
The picture url comes back as hosted on https facebook servers.

Links like the one above. For some reason i'm receiving this Security error whenever loading up the image from my flash as3 facebook app.
Below is the code i'm using to fetch the image.
[code]
public function setupPhoto(url:String):void
{
removeAllChildren();
var urlRequest1:URLRequest = new URLRequest(url);
this.loader1 = new Loader();
this.loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteLoadingImage);
this.loader1.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onErrorLoadingImage);
this.loader1.load(urlRequest1);
//imageLoader = new ImageLoader(url);
//imageLoader.addEventListener(Event.COMPLETE, onCompleteLoadingImage);
//imageLoader.load();
}
private function onErrorLoadingImage(e:IOErrorEvent):void
{
debugPanel.writeLine("ERROR LOADING IMAGE!!!");
debugPanel.writeLine(e.text);
}
public function onCompleteLoadingImage(e:Event):void
{
//var sprite:Sprite = this.loader1.content as Sprite;
//updatePicture(sprite);
updatePicture1(this.loader1.content);
}
[/code]
this works for me with Facebook:
var lc:LoaderContext = new LoaderContext(true, null, null);
// now add the LoaderContext to your loader
this.loader1.load(urlRequest1, lc);
you don't have to create a LoaderContext every time, just create it once and use everywhere.
I've been working on a program, but currently I'm stuck.
My problem is the .content statement in my script. Since I'm loading a PNG from the web I have the Local playback security set to "Access network only". When I load pictures locally (of course with settings at "Access local files only", and local URLRequests) the program works just fine, but when loading from the web the .content makes my program stop, I've found this out with lots of testing. It seems the .content only works when the SWF file only uses local requests, is this correct?
I know that I can use addChild(loader), but I need to get the PNG file out of the loader so that I can turn it into a bitmap and edit it. Any ideas? The script is below.
var loader:Loader = new Loader;
var ar:Array = [];
var teller:Number = 0;
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, paste);
knapp.addEventListener(MouseEvent.CLICK, neste);
function paste(evt) {
ar[teller] = loader.content;
ar[teller].x = ar[teller].width*teller;
addChild(ar[teller]);
}
function neste(evt) {
teller ++
loader.load( new URLRequest ("http://www.minecraft.net/skin/Notch.png"));
}
loader.load( new URLRequest ("http://www.minecraft.net/skin/Notch.png"));
Cross-domain policies prohibits image data manipulation for images loaded from another domain than the one the swf file is loaded from:

Hello i am trying to capture my camera as an flv file with fms 4.5 i am doing the following:
protected function rec_clickHandler(event:MouseEvent):void
{
nc = new NetConnection();
nc.client = { onBWDone: function():void{ trace("onBWDone") } };
nc.connect("rtmp://localhost/vod");
nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
}
private function netStatusHandler(e:NetStatusEvent):void {
var code:String = e.info.code;
if(code == "NetConnection.Connect.Success"){ //in case of recording...
ns = new NetStream(nc);
ns.attachCamera(cam);
ns.attachAudio(mic);
ns.publish("filename","record");
}
else{
trace(code);
}
}
but i get the following error:
Error #2044: Unhandled NetStatusEvent:. level=error, code=NetStream.Record.NoAccess
Can anyone help? what am i doing wrong?
This status message, NetStream.Record.NoAccess, generally indicates that you don't have write permissions to the stream. Check the permissions of your streams dir to see if it is read only.
If that is not the issue, check which application are you trying to publish to, does not SSAS that has code to deny write access to stream
Make sure the previously recorded video is not being opened in any video player. If it is being accessed by some other program, it will not allow you to record or rewrite it.
I threw together a simple app in flash ide / as3 that pulls photos from a foursquare location. It works locally but once deployed on the web it does not work. I would guess it's a crossdomain issue but what I've found online (link below) so far doesn't answer my question.
http://groups.google.com/group/foursquare-api/browse_thread/thread/ab963f74fde8ae9f/3e68559966acf7c9
I've checked the local vs network setting.I've read I shouldn't need a crossdomain file on my server.
And I believe I've read that I shouldn't need a php proxy for foursquare like I need with twitter...
Not sure what else it can be.
the box where it says testing should trace the response but it never fills, it's like the call stops dead in its tracks after it hits the crossdomain file on foursquare and I don't even get an error response. http://physicalgraffitea.com/wp-content/swf/Foursquare-e.swf
Distilled the AS3 down to it's leanest here, sans the ID and Secret.
Any help? Thanks
Security.allowDomain("http://www.foursquare.com");
Security.loadPolicyFile("http://api.foursquare.com/crossdomain.xml");
import flash.net.URLRequest;
import flash.net.URLLoader;
import com.adobe.serialization.json.JSON;
var resource = "https://api.foursquare.com/v2/venues/4b7071c8f964a520d51a2de3/photos?group=venue&limit=6&client_id="+myId+"&client_secret="+mySecret+"&v=20120517";
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest(resource);
request.method = URLRequestMethod.GET;
loader.addEventListener(Event.COMPLETE, onComplete);
loader.addEventListener(IOErrorEvent.IO_ERROR,onIOError);
loader.load(request);
function onComplete(e:Event):void {
var loader:URLLoader = URLLoader(e.target);
outputtxt.text = loader.data;
trace(loader.data);
var jsonData:Object = JSON.decode(loader.data)
}
function onIOError(e:Event):void {
var loader:URLLoader = URLLoader(e.target);
outputtxt.text = "error " + loader.data;
}
After a lot of fussing around the only way I could get it to work is to yes, use a crossdomain proxy php file with the foursquare api.
But that alone didn't solve my problem the swf needed to be referenced with the full http path but without the "www" in the path. "http://mydomain.com/swf/file.swf"
Not sure why but if you have similar cross domain issues try removing the www too
EDIT: Due to the answer I change the code posted. I've added the Security.allowDomain("*") line and that line throws me an error. So, how can that be made?
I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
private function loadSwfApplication()
{
// The next line throws me an error.
Security.allowDomain("*");
var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf");
swfLoader.addEventListener(Event.COMPLETE, loadComplete);
swfLoader.load(urlRequest);
}
private function loadComplete(completeEvent:Event)
{
var swfApplication:* = completeEvent.target.content;
swfApplication.init(); // this is a Function that I made it in the Root class of swfApplication
}
]]>
</mx:Script>
<mx:SWFLoader id="sfwLoader"/>
</mx:WindowedApplication>
The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception:
Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf.
This is because somewhere in application.swf I use the stage like this:
if (root.stage != null)
root.stage.addEventListener(Event.REMOVED, someFunction);
root.stage.stageFocusRect = false;
How can I load this swf application and USE the stage without any problems?
You can try to load your SWF temporarily into a ByteArray and then load it with your SWFLoader.
Don't forget to set allowCodeImport to true since your SWF has as code inside.
Of course be sure that your loaded swf is secure enough for your application since it will have access at all your property.
private function loadSwfApplication():void {
// load the file with URLLoader into a bytearray
var loader:URLLoader=new URLLoader();
// binary format since it a SWF
loader.dataFormat=URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, onSWFLoaded);
//load the file
loader.load(new URLRequest("path/to/the/application.swf"));
}
private function onSWFLoaded(e:Event):void {
// remove the event
var loader:URLLoader=URLLoader(e.target);
loader.removeEventListener(Event.COMPLETE, onSWFLoaded);
// add an Application context and allow bytecode execution
var context:LoaderContext=new LoaderContext();
context.allowCodeImport=true;
// set the new context on SWFLoader
sfwLoader.loaderContext = context;
sfwLoader.addEventListener(Event.COMPLETE, loadComplete);
// load the data from the bytearray
sfwLoader.load(loader.data);
}
// your load complete function
private function loadComplete(completeEvent:Event):void {
var swfApplication:* = completeEvent.target.content;
swfApplication.init(); // this is a Function that I made it in the Root
// class of swfApplication
}
If they are being loaded from different domains you are going to have to add a security exception - http://livedocs.adobe.com/flex/3/html/help.html?content=05B_Security_08.html
if its being run locally youre probably going to have to add them to the list of trusted files or folders in the settings manager - http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html#117502
Assuming that the external SWF is also in the application directory, you could try loading it using the app:/ scheme:
var urlRequest:URLRequest = new URLRequest("app:/path/application.swf");
That may put it into the same security context as the main application.
One thing you may want to consider is that if you are trying to run a SWF from inside your application directory in AIR, AIR restricts execution of files. If you copy the file to a temp file and the run it (along with allowLoadBytesCodeExecution set to true) then it works.
var file:File = File.applicationDirectory.resolvePath("myFile.swf");
this.tmpFile = File.createTempDirectory().resolvePath("myFile.swf");
file.copyTo(this.tmpFile);
imagePreview.loaderContext = lc;
imagePreview.source = tmpFile.url;
it won't work for Flex Projectors.
Only we use SWFLoader and LocalConnection because they can communicate between external swf and main swf. Thanks for support!
Can you read my tutorial from Adobe's Forum
It is very better than MovieClip or Object-Callers
Thank for resolved solution :)
