I have a piece of AS code that must be translated to javascript. Most of the things work okay now but only uploading (in chunks) fail. I get a message back from the server "Different file size". I think the way javascript post raw data differs from AS3's UrlRequest with FormData.
For example:
- AS3: urlRequest.data = [ByteArray]
- JS : Formdata.append('data', [FileBlob] )
Does this have the same result?
The AS3 code is:
private function sendData() : void
{
this._filePieceReadyToUpload = false;
this._bytesToSend = new ByteArray();
this._fileStream.readBytes(this._bytesToSend, 0, this._fileStream.bytesAvailable);
this._currentOperation = this.OP_DATA;
this._urlRequest = new URLRequest(_uploadScriptPath + "?op=" + this.OP_DATA + "&secure=" + _loginSecureHash + "&user_id=" + _userId + "&crc=" + this._headerCRC + "&size=" + this._bytesToSend.length + "&position=" + this._piecePosition + "&md5=" + this._fileCurrent.$md5 + "&api_id=" + _apiID);
this._urlRequest.method = URLRequestMethod.POST;
this._urlRequest.data = this._bytesToSend;
this.startURLRequstLoadTimer();
return;
}
Translated into this (javascript):
o.uploadFileBlob = function( blobFile, iBlobPos, sCrc )
{
var fd = new FormData();
fd.append( 'data', blobFile ),
xhr = new XMLHttpRequest(),
sGetVars = 'op=data'+
'&secure='+o.apik_secureHash+
'&user_id='+o.apik_userId+
'&crc='+sCrc+
'&size='+blobFile.size+
'&position='+iBlobPos+
'&md5='+
'&api_id=4';
xhr.upload.addEventListener("progress", function(e) { $d('progress'); }, false);
xhr.addEventListener("load" , function(e) { $d('upload complete'); }, false);
xhr.addEventListener("error", function(e) { $d('failed '+xhr.status+': '+xhr.statusText+' : '+xhr.responseText);
//alert( xhr.getAllResponseHeaders().toLowerCase() );
}, false);
xhr.addEventListener("abort", function(e) { $d('upload abort'); }, false);
xhr.open('POST', o.apik_address+'?'+sGetVars, true );
xhr.onload = function(e) { $d('xhr loaded'); };
return xhr.send(fd);
}
Can explain somebody to me what the difference is between the AS and JS version. Is a POST field 'data' in javascript the same as urlRequest.data in AS? What am I doing wrong?
