Apache flex 在Flex2中上传时如何获取文件的字节数组

现在，我使用flex 2&执行以下操作：

     There is a WSDL which have one method which take byteArray & fileName(which i want to write) as a parameter to write a file in local system, the following is the code...

public void writeLocation(byte[] byteToWrite, String fileName) throws FileNotFoundException
{
    StringBuffer fileLocation = new StringBuffer("D:\\Products\\Device");
    fileLocation.append("\\"+fileName);
    File file = new File(fileLocation.toString());
    BufferedOutputStream bufferWriter = new BufferedOutputStream(new FileOutputStream(file));
    try 
    {
        bufferWriter.write(byteToWrite);
    }
    catch (IOException e) 
    {
        System.out.println("Error file Writing....");
        e.printStackTrace();
    }
    finally
    {
        try 
        {
            bufferWriter.close();
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
    }
}

但是当我搜索时显示错误的Flex2我在Flex2中发现没有“数据”属性。因此，我无法将所选对象创建到byteArray中。。有人能帮我怎么做吗不想使用HTTPService（POST方法）

请帮忙。。提前感谢

该功能在FP 9中不可用。你需要这样做

但是，这是为Flex3设计的，因此它可能适用于框架的旧版本，也可能不适用于框架的旧版本。无论哪种方式，问题是您使用的功能在您使用的版本中不可用
