Get Current Browser URL - ActionScript 3 - actionscript-3

I'm trying to get current browser url. I have already tried with External Call, and it didn't work. And with loaderInfo.url I receive the current SWF url.

Give this a go:
import flash.external.ExternalInterface;
var url:String = ExternalInterface.call("window.location.href.toString");
if (url) textfield.text = url;
should do the trick.

There are a couple of ways to solve this problem, however all of them involve the use of JavaScript to query the browser directly.
My preferred way to solve this problem would be to provide the URL via a flashVar property, direct from the embed code (personally, I would reccomend using SWFObject to make this easier); don't forget you will need to URL Encode it to avoid markup issues.
var flashvars = {
browserURL: escape(location.href)
};
swfobject.embedSWF("myContent.swf", "myContent", "300", "120", "9.0.0", "expressInstall.swf", flashvars);
Now you will be able to access the Browser URL via the loaderInfo object:
trace(stage.loaderInfo.parameters["browserURL"]);
note that this will only work if you have control of generated HTML for your SWF file - if users are going to be grabbing the SWF and writing their own embed HTML, it's not going to work.
If you don't have control of the flash embed HTML, then you will need to get flash to query the browser at runtime using the ExternalInterface class; other people have suggested the use of "window.location.href.toString" however this can prove problematic in IE6, I find the following works reliably across all browsers
const browserURL : String = ExternalInterface.call("eval", "window.location.href");
Note that in order for this to work, you will need to grant JavaScript access to your Flash movie, this is done, again, via the HTML embed code and the allowScriptAccess param

var url:String = loaderInfo.loaderURL;
seems to work too.

I would try passing the required info in as a flashvar. Not the best out of the box solution I know, but it will work.
Flash: FlashVars in AS3

i think its posible to use the external interface an do it with javascript window.location

I have been using flash for a long time and never noticed this one. It only gives the domain though for security. It does work through loaded swfs as well. Not sure about iframes.

How does Google Swiffy implement clickTag for HTML5 banner ads?

First, I tried finding an option to prevent Swiffy from compressing/minifying all the data when doing an export to HTML5 from Adobe Flash Pro. But no dice.
Even if I was able to read the unminified Javascript that Swiffy exported, I don't think there would be a simple function call for the "clickTag".
It's likely defining the variable clickTag in the huge haystack of {index: #, type: #}, and then doing processing each operations to eventually call the window.open() method (or something similar).
This is how it currently outputs (minified)
Does anyone have any clue how Swiffy implements clickTag?
Or what would be the Javascript equivalent that does the same job?
Swiffy uses the core API of the environment where the ad is served. If it's a DoubleClick Rich Media ad, it does use Enabler.exit("url").
If you want to have a better control on your output file, I'd suggest having a look at Google Web Designer. The closest experience to flash development in the HTML5 - JS era.
Google instructions are here, for plain HTML5 (non-swiffy) click tags.
At the bottom of the file is a snippet of code like this:
<script>
var stage = new swiffy.Stage(document.getElementById('swiffycontainer'),
swiffyobject, {});
stage.start();
Add this right before stage.start(); to mimic previous flash behavior. Ensure you use the proper capitalization.
stage.setFlashVars("clickTAG=http://stackoverflow.com");
**Note: Ensure to use url encoding if there are parameters...doesn't seem to like it otherwise

others way to load sound for webaudioAPI except xmlhttprequest

is there any other way to load webaudioAPI except xmlhttprequest ??
it seems xmlhttprequest can only played with local server like "localhost/blablabla"
I want make my game can play locally without any serverside like 'file:///E:/blablabla'
thx
regards
Well, you could recode the file as a data: URL.
what is your goal when using the audio api? There are two things to use as a source. First, you can use the Source node, which you specify 192000Hz PCM. This is decoded by the .decodeAudioData as you know, from an arraybuffer. This takes a lot of time and power. A second much easier method is to use the <audio> tag. You can give this an src (even with file:///E:/blablabla), which loads pretty fast or specify it with a data-url (also much faster than the context.decodeAudioData).
Example HTML:
<audio src="E:/blablabla.mp3"></audio>
Example JS:
window.audiotag = document.getElementsByTagName('audio')[0];
function audioReady() {
window.AudioContext = window.AudioContext||window.webkitAudioContext;
context = new AudioContext();
source = context.createMediaElementSource(audiotag);
source.connect(context.destination);
audiotag.play();
}
audiotag.onload = audioReady();
This simply lets audio play from the audio tag, but when the audio tag gets connected to the sourcenode, it automatically mutes and sends it audio to the audio-api.

firefox does not load an xml into an swf called by a parameter in the html-code (works fine in IE)

I built an excercise in flash cs5/as3. It draws its content from an xml-file.
Because I want to make it easy for other people to create their own excercise based on this swf, I want the actionscript to load the xml, with the filename based on a parameter in the html code.
In this case the xml is called oef01.xml
The link would look like this: BoFlitsOefening.swf?id=oef01
And the actionscript like this:
public function Main ()
{
//myFile is a string I declared earlier
myFile = LoaderInfo(this.root.loaderInfo).parameters["id"];
myFile += ".xml";
loadXml ();
}
function loadXml ():void
{
xmlLoader = new URLLoader(new URLRequest(bestand));
xmlLoader.addEventListener (Event.COMPLETE,xmlLoaded);
}
function xmlLoaded (event:Event):void
{
myList = new XML(event.target.data);
myList.ignoreWhite = true;
}
The construction is working fine in Internet Explorer but not in Firefox. I have done internet research but I could not find an explanation or a solution I was able to apply, though the issue is known.
Are you testing it on the server or locally - the URL in your browser should start with http:// not file:///?
It should work fine on the internet, while locally the URLs containing ? may not resolve properly.
In that case you may use FlashVars instead - you don't need to change the AS code, just HTML/JS.
And on a side note: you may try to embed the SWF file using SWFObject - some crossbrowsers issues are caused by wrong/buggy embedding code.
Also FireFox likes to keep external sources cached, so there's a likelihood that it's loading an old file. Make sure you clear the cache after updating the xml.
there is a way of tricking it to load it fresh every time by adding some junk after, like
.../my.xml?rand=001820018
where you generate the number randomly every time, if I remember correctly

FlashVars syntax problem

I've got the following javascript writing HTML for FlexPlayer:
document.writeln("<object width=\"489\" height=\"414\" FlashVars=\""+videoSource+"\">");
document.writeln("<param name=FlashVars value='sourceUrl=videoSource'>");
I need to have FlashVars="sourceUrl=videoSource"; where videoSource is a variable which I get from PHP for the current video and sourceUrl is variable form the Flex player. Please repair the int he first row cause this FlashVars syntax is driving me mad.
You should use SWFObject as an easier way to embed your swf into your website. It also has a very simple way to include parameters (flashvars) into your movie in the documentation.

Load profile image from Facebook with Actionscript 3

I'm trying to load profile images (friend images) from Facebook with AS3 but I seem to be running into a security issue.
I'm currently using the "official" Adobe Facebook API for Actionscript 3 which works fine. However, I seem to be having trouble loading profile images when running my application in a browser. The images load fine when running in the Flash IDE.
The images are being loaded from https://graph.facebook.com and there seems to be a crossdomain.xml policy on that domain:
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" secure="false" />
<site-control permitted-cross-domain-policies="master-only" />
</cross-domain-policy>
In other sources I found that adding a ContextLoader to my Loader object when loading the image should solve the problem but this doesn't seem to be the case either:
loader = new Loader();
// add some listeners here...
loader.load( new URLRequest( "imageurl" ), new LoaderContext(true) );
I'm not quite sure how to proceed at the moment. I was hoping that the Adobe Facebook API would provide assistance in this but I can't seem to find anything that solves this issue.
Any help greatly appreciated.
UPDATE:
I just noticed that when I visit one of the images in a browser that I'm actually redirected to Facebook's CDN where the actual image is stored. When I hard-code the image url with the redirected URL I can load the image in the browser. It seems that this is not a security issue after all but a redirection issue.
If this is a redirection issue then the question would become; How can I have Flash Player load an image from a redirected URL?
UPDATE 2:
It seems that the URLRequest class has a followRedirects property which is only available in AIR.
UPDATE 3:
I'm currently using a PHP script to get me the redirected URL as a work around but this of course is far from ideal and potentially a big strain on my server.
I had the same problem and it looks like you have to manually load the crossdomain file of the domain you are redirected to in actionscript. For now, it looks like all facebook profile images are finally loaded from the domain http://profile.ak.fbcdn.net/.
I just added this line before loading the images:
Security.loadPolicyFile("http://profile.ak.fbcdn.net/crossdomain.xml");
This should allow for loading the redirected images, as long as the redirect domain does not change. ;)
You can use a URLLoader and load the image as a ByteArray. This appears to work regardless of the redirect. You can then use the ByteArray as the source for an Image/BitmapImage or use a Loader to load the bytes as you would have the image url in the first place.
For example:
var urlRequest:URLRequest = new URLRequest("http://graph.facebook.com/id/picture");
var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
urlLoader.addEventListener(Event.COMPLETE, completeHandler);
urlLoader.load(urlRequest);
function completeHandler(event:Event):void
{
var byteArray:ByteArray = loader.data;
// Then either:
bitmapImage.source = byteArray;
// or:
var loader:Loader = new Loader();
...
loader.loadBytes(byteArray);
...
}
it should be a relitively easy thing to do, all of the facebook profile images can be found by using the picture root of the graph API. like this link:
"http://graph.facebook.com/" + userid + "/picture"
I would like to confirm martin's solution here.
My case goes from testing the application on AIR platform which is fine and works great, the image loaded successfully.
But when I port it into canvas app on facebook then I face a problem, the profile images won't come along, it cannot load.
I use what martin suggest here. And if you track a url redirection, you will see that actually image profiles are located at that CDN server not facebook itself, so you need to load that domain's policy file according to actionscript's security-sandbox.
Thanks again.
totally guessing but you could use URLLoader to get the data from the redirected call, then parse it together into a picture xD
I am using two loadPolicyFile calls, as it seems there are 2 possible CDNs that facebook uses. This is working for me but of course, a generic solution is preferable, facebook might again add another CDN and things would just stop working on their own --
Security.loadPolicyFile('http://profile.ak.fbcdn.net/crossdomain.xml');
Security.loadPolicyFile('http://profile.cc.fbcdn.net/crossdomain.xml');
The URLLoader solution suggested by #Stiggler might work. I haven't tried. But it seems heavier compared to using a Loader object.
Since there are a lot of domains where Facebook stores it's photos I wrote a little script that uses the domain of the image to load the appropriate policy file:
import com.adobe.net.URI;
import flash.system.Security;
var someFacebookImageUrl:String = "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/c66.66.828.828/s160x160/537210_440478782684964_233907781_n.jpg";
var uri:URI = new URI(someFacebookImageUrl);
Security.loadPolicyFile(uri.scheme + "://" + uri.authority + "/crossdomain.xml");
Nice this is that it works not only for the profile images but for all images facebook uses.
Hope this helps some of you!
PS: The URI class is part of the as3 core lib: http://code.google.com/p/as3corelib/
