Question

I have bitmapData. I want to upload it to a server using URLLoader. I tried many ways, but with no result. This is my current code in ActionScript 3:

import flash.net.URLLoader;
import flash.net.URLRequest;
import mx.graphics.codec.JPEGEncoder;
...
var jpg:JPEGEncoder = new JPEGEncoder();
var myBytes:ByteArray = jpg.encode(bitmapData);
var uploader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("uploadFile.php");
request.contentType = "application/octet-stream";
request.data = myBytes;
uploader.load(request);

I take an object bitmapData and encode it to jpg. After that I try to send jpg-bytes to the file "uploadFile.php" on the server. But there are neither errors nor positive result. I will be grateful for any suggestions/advices.

这是此前使用的AS3代码I ve,这就要求申请机构提供双轨数据:

var url_request:URLRequest = new URLRequest();
url_request.url = "http://server.com/upload.php";
url_request.contentType = "binary/octet-stream";
url_request.method = URLRequestMethod.POST;
url_request.data = myByteArray;
url_request.requestHeaders.push(
 new URLRequestHeader( Cache-Control ,  no-cache ));

var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
// attach complete/error listeners
loader.load(url_request);

我注意到,你没有确定数据格式,也没有确定数据格式。

请注意,这可以成为你重新进入的一个安全问题。我看到了这样的情况,即这种守则必须针对用户行动加以执行(如纽扣)。

您还应核对服务器记录,看看该请求是否使服务器收到。请注意,没有完全合格的url(从http://www.un.org开始),该服务器就从与您的SWF档案相同的地点为你的PHP文档服务。

Your encoding of the image will break it because jpg data contains non-ascii characters.
Changing your contentType type to "image/jpeg" should fix it however this statement is untested.

When I send JPG to the server I always base64 encode it first and then decode it on the server side.

import mx.utils.Base64Encoder;

var b64:Base64Encoder = new Base64Encoder()
b64.encodeBytes( myBytes )
var encodedb64.toString();

request.data = b64.toString();
