POHttpStatus 0 when writing file from AS3 to PHP using URLLoader
text
Body
copied!<p>I'm doing a project in AS3 where the user can design something and order it after. The design is exported to a PDF, PNG and XML. These files I want to save on the server. On MAMP it all works and I get the HTTPStatus 200, note that I run my SWF from MAMP but the php-script is successfully accessed on the <strong>remote server</strong> and the files are written to the Remote server with succes as well. However when i copy the SWF to the remote server, the files do not save and I get a HTTPStatus 0.</p> <p>In the class that I use (see AS3 code below) I use a URLLoader to get to the following one line php script:</p> <pre><code><?php file_put_contents($_POST['location'] . $_POST['fileName'], base64_decode($_POST['fileData'])); </code></pre> <p>Here the AS3 class:</p> <pre><code>public class ServerConnection extends Sprite { private var _files:Array = new Array(); private var _fileNames:Array; private var _fileLocation:String = ""; private var _scriptLocation:String; private var _fileSavesInProgress:Array = new Array(); public function ServerConnection(scriptLocation:String = null, files:Array = null, fileNames:Array = null) { if (scriptLocation) setScriptLocation(scriptLocation); if (files) setFiles(files); if (fileNames) setFileNames(fileNames); } public function encodeFiles():void { for(var i:uint = 0; i < _files.length; i++) { _files[i] = encodeFile(_files[i]); } } public function encodeFile(byteArray:ByteArray):Base64Encoder { var base64:Base64Encoder = new Base64Encoder(); base64.encodeBytes(byteArray); return base64; } public function saveFiles(location:String = null):void { if (location) setFileLocation(location); for(var i:uint = 0; i < _files.length; i++) { _files[i] = saveFile(_files[i], _fileNames[i]); } } public function saveFile(encodedFile:Base64Encoder, fileName:String = "test"):void { var data:URLVariables = new URLVariables(); data.fileData = encodedFile; data.fileName = fileName; data.location = _fileLocation; this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: a save file request was made for " + fileName + "\n" + "url: " + _fileLocation + "\n" + " scriptLocation: " + _scriptLocation + "\n" )); var request:URLRequest = new URLRequest(_scriptLocation); request.method = URLRequestMethod.POST; request.data = data; var loader:URLLoader= new URLLoader(); loader.addEventListener(Event.COMPLETE, function(e:Event):void {fileSaved(loader);}); loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatus); loader.addEventListener(IOErrorEvent.IO_ERROR, ioError); _fileSavesInProgress.push(loader); try { loader.load(request); } catch (e:*) { this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: error:* = " + e + " \n")); } //navigateToURL(request); } public function displayObjectToPNG(displayObject:*, scale:Number = 1):ByteArray { var bmpData:BitmapData=new BitmapData(displayObject.width, displayObject.height, true, 0xFFFFFF); bmpData.draw(displayObject); var byteArray:ByteArray = PNGEncoder.encode(bmpData); return byteArray; } public function xmlToByteArray(xml:XML):ByteArray { var byteArray:ByteArray = new ByteArray(); byteArray.writeUTFBytes(xml); return byteArray; } public function setScriptLocation(url:String):void { _scriptLocation = url; } public function setFileLocation(url:String):void { _fileLocation = url; } public function setFiles(array:Array, encode:Boolean = true):void { for each(var file:* in array) { for each(var type:XML in describeType(file).extendsClass.@type) { if (type == "flash.display::DisplayObject") file = displayObjectToPNG(file); } if (typeof(file) == "xml") { file = xmlToByteArray(file); } _files.push(file); } if (encode) encodeFiles(); } public function setFileNames(array:Array):void { _fileNames = array; } // EVENTS private function httpStatus(e:HTTPStatusEvent):void { this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: status = " + e.status + " \n")); } private function ioError(e:IOErrorEvent):void { this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: IOErrorID = " + e.errorID + " Message: "+ e.text + " \n")); } private function fileSaved(loader:URLLoader):void { this.dispatchEvent(new DebugEvent(DebugEvent.MESSAGE, "@serverConnection: file save completed.

I do think that the fact that navigateToURL does work and loader.load(request) doesn't say something about the problem... but what? </p> <p>I'm kind of stuck on this and would appreciate help. Thanks in advance!</p> <p>PS: for testing I have set the permission of the remote DIR to 777. Furthermore the files are successfully saved from MAMP to Remote anyhow as stated before.</p>
