Unexpected Flash Security Exception When Using URLLoader

Question

What I am trying to accomplish is to upload some binary data, specifically a ByteArray representing a PNG image, to a server using the URLLoader class in conjunction with UR

Answer 1

It could be possible that contentType does not refer to what data you send, but to what data you receive. Try to set the requestHeaders, that should work:

urlRequest.requestHeaders.push(new URLRequestHeader('Content-type', 'multipart/form-data'));

Also, I've found a piece of code where in one of my projects. The code works and sends some binary JPEG data to the server, using POST. I dit it some time ago and I can't explain why I did the things this way, but maybe it helps. I'm pasting it as is:

function sendData(submitPath:String, descriere:String):void {
    // building the url request for uploading the jpeg to the server
    var header:URLRequestHeader = new URLRequestHeader('Content-type', 'application/octet-stream');
    var jpgURLRequest:URLRequest = new URLRequest(submitPath+'/id/'+player.id+'/path/'+player.contentPath.replace('/','')+'/width/'+player.videoWidth+'/height/'+player.videoHeight+'/descriere/'+descriere+'/timp/'+time);
    jpgURLRequest.requestHeaders.push(header);
    jpgURLRequest.method = URLRequestMethod.POST;
    jpgURLRequest.data = screenShot;

    // sending the data to the server
    var sender:URLLoader = new URLLoader();
    sender.load(jpgURLRequest);
}
