Facebook API 100 Error

问题

Been receiving this error when trying to post on a feed. I am using JavaScript to post. The ByteArray data is coming from a .swf

API Error Code: 100

API Error Description: Invalid parameter

Error Message: picture URL is not properly formatted

Here is my AS3:

var bdToSave:BitmapData = new BitmapData(s.width,  s.height);
        bdToSave.draw(s, null, null, null, null, true);
        var encoder:JPGEncoder = new JPGEncoder();
        var byteArray:ByteArray = encoder.encode(bdToSave);

        if (ExternalInterface.available) ExternalInterface.call("publishStream", byteArray);

Here is my JS:

function publishStream(person)
        {

            FB.ui({ 
                    method : 'feed', 
                    name: 'I just painted my face!',
                    caption: 'From the show Warren, using the True Colors: Face Painting App I painted my face to match my favourite team!',
                    link:  'https://www.facebook.com/fanunitednet',
                    description: '',
                    picture: person
                  });
        }

I am sending it a byte array of data. Is it possible to get it working using that or do I need a URL? My issue is that I'm taking a picture, sending the bytearray of data to the form and then trying to use that picture.. there is no direct link.

Thoughts?

You need to upload the image via the Graph API first, for example like it's described here:

https://developers.facebook.com/docs/graph-api/reference/user/photos/#publish

This mean via a POST request to /{user_id}/photos as multipart/form-data mime-type, and the byteArray as source parameter.

Remember that you need the publish_actions permission to be able to do this!
