facebook photo upload via image data - facebook

Question

I'm using graph api v2.1. AS3-code generates data, calls JS-code via ExternalInterface, JS-code calls FB API
I'm able to upload photo via {image-url}, but getting error when trying to upload photo via {image-data}:
{message: "(#324) Requires upload file", type: "OAuthException", code:
324}
I guess, i'm formatting {image-data} wrong. here is my code:
AS3:
var id:int = Math.random()*10000;
var stream:ByteArray = new ByteArray();
var imageName:String = id.toString() + ".png";
var boundary:String = "I" + id.toString();
stream.writeUTFBytes(
'Content-Type: multipart/form-data; boundary=' + boundary +
'\r\n\r\n--' + boundary +
'\r\nContent-Disposition: file; filename="' + imageName + '"' +
'\r\nContent-Type: image/png' +
'\r\nContent-Transfer-Encoding: binary' +
'\r\n\r\n');
stream.writeBytes(picture);
stream.writeUTFBytes("\r\n--" + boundary + '--\r\n');
if (ExternalInterface.available)
{
ExternalInterface.call('savePhoto', stream, null, id);
}
JS:
function savePhoto(bytes, url, requestId)
{
var data;
if (bytes != null)
data = {"source": bytes, "no_story":true}; //getting error
else
data = {"url": url, "no_story":true}; //works fine
FB.api(
"/me/photos",
"POST",
data,
function (response)
{
//handle response
}
);
}
UPD:
Here is how picture initialised:
[Embed(source="../res/logo_2.png", mimeType="image/png")]
private var testImage:Class;
<...>
var data:Bitmap = new testImage() as Bitmap;
var picture:ByteArray = PNGEncoder.encode(data.bitmapData);

Answer 1

Did you try base64?
var params: Object = new Object;
var encoder:JPGEncoder = new JPGEncoder(75);
var bytes:ByteArray = encoder.encode(bmp.bitmapData);
params.message = message;
params.image = bytes;
params.fileName = "image.jpg";
Facebook.api("/me/photos",null,params,"POST");

Answer 2

Try this code to prepare data:
var pngData:ByteArray = PNGEncoder.encode(image.bitmapData);
var strForStart:String = "\r\n--" + boundary + "\r\n" + "Content-Disposition: form-data; name=\"photo\"; filename=\"file1.png\"\r\n" + "Content-Type: image/png\r\n\r\n" + "";
var strForEnd:String = "--" + boundary + "\r\n" + "Content-Disposition: form-data; name=\"Upload\"\r\n\r\n" + "Submit Query\r\n" + "--" + boundary + "--";
var beginBA:ByteArray = new ByteArray();
beginBA.writeMultiByte(strForStart, "ascii");
var endBA:ByteArray = new ByteArray();
endBA.writeMultiByte(strForEnd, "ascii");
var resultBytes:ByteArray = new ByteArray();
resultBytes.writeBytes(beginBA, 0, beginBA.length);
resultBytes.writeBytes(pngData, 0, pngData.length);
resultBytes.writeBytes(endBA, 0, endBA.length);
