Error #2044 when trying to save image from Flash using php

I get this error in the debugger version of flash Player Error #2044: Unhandled ioError:. text=Error #2032: Stream Error

i searched the net for an explanation without success

the code below works in WampServer http://localhost/ but not when i put it online on the server:

as3 :

import com.adobe.images.JPGEncoder;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequestHeader;
import flash.net.URLRequest;


var jpgSource:BitmapData = new BitmapData(img_mc.width,img_mc.height);
jpgSource.draw(img_mc);
var jpgEncoder:JPGEncoder = new JPGEncoder(85);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

//set the request's header,method and data
var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");
var loader:URLLoader = new URLLoader();
//sends jpg bytes to saveJPG.php script
var myRequest:URLRequest = new URLRequest("saveJPG.php");
myR开发者_如何学Pythonequest.requestHeaders.push(header);
myRequest.method = URLRequestMethod.POST;
myRequest.data = jpgStream;
loader.load(myRequest);
//fire complete event;
loader.addEventListener(Event.COMPLETE,saved);
function saved(e:Event)
{
    //trace the image file name
    trace(loader.data);
}

saveJPG.php:

if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {


//the image file name   
$fileName = 'img.jpg';

// get the binary stream
$im = $GLOBALS["HTTP_RAW_POST_DATA"];

//write it
$fp = fopen($fileName, 'wb');
fwrite($fp, $im);
fclose($fp);

//echo the fileName;
echo $fileName;


}  else echo 'result=An error occured.';

update:

i tried $im = file_get_contents("php://input");

instead of $im = $GLOBALS["HTTP_RAW_POST_DATA"];

and i got the same error.

var myRequest:URLRequest = new URLRequest("saveJPG.php");

Try to set complete url for request.

Error #2044: Unhandled ioError:. text=Error #2032: Stream Error

Do what it wants add the unhandled ioError eventlistener

loader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler );
function ioErrorHandler( e:Event ):void{
  trace('ioErrorHandler ' + e.toString() )
}

And you should have this one also

loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler );
function securityErrorHandler ( e:Event ):void{
  trace('securityErrorHandler ' + e.toString() )
}

it seems that the server is preventing me from exchanging bytes or using $GLOBALS["HTTP_RAW_POST_DATA"]; or something like that.

so i come up with different approach, instead of sending the image as bytes to php file i'll send it as hexadecimal string:

import com.adobe.images.JPGEncoder;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequestHeader;
import flash.net.URLRequest;


var jpgSource:BitmapData = new BitmapData(img_mc.width,img_mc.height);
jpgSource.draw(img_mc);
var jpgEncoder:JPGEncoder = new JPGEncoder(80);
var jpgStream:ByteArray = jpgEncoder.encode(jpgSource);

//get the whole jpgStream as a string of hex
var hexStream:String="";
for (var i:int=0;i < jpgStream.length ; i++)
{
    hexStream += decToHex(jpgStream[i]);
}

function decToHex(dec:int):String
{
    var hex:String = dec.toString(16).toUpperCase();
    if (dec<16)
    {
        hex = "0"+hex;
    }
    return hex;
}

//transfer hexStream to the server

var variables:URLVariables = new URLVariables();
variables.hexStream = hexStream;

var myRequest:URLRequest = new URLRequest("saveimg.php");
myRequest.method = URLRequestMethod.POST;
myRequest.data = variables;

var loader:URLLoader = new URLLoader(myRequest);
loader.dataFormat = URLLoaderDataFormat.BINARY
loader.load(myRequest);

file_put_contents('img.jpg', pack('H*', $_POST['hexStream']));

obviously this is slower than using HTTP_RAW_POST_DATA but hey
