Question

发送图像时发生错误客户端 - 服务器 - 客户端是“损坏的JPEG数据：4350674标记0xd9之前的无关字节”我可以更改什么？这是我的代码：

服务器

 InputStream is = klienciRemoteScreen[1].getInputStream();
 OutputStream os = klienciRemoteScreen[0].getOutputStream();                            

                  byte[] bytesize = new byte[4];                              
                  is.read(bytesize);                                                                              
                  int size = ByteBuffer.wrap(bytesize).asIntBuffer().get();
                  byte [] image= new byte [size];
                  byte[]bufferimage = new byte [1];
                  os.write(bytesize);
                  os.flush();
                  int count;
                  while((count = is.read(image)) > 0)
                  {
                     os.write(image);
                     os.flush();                                                          
                   }
                     os.close();

客户端将图片发送到服务器

OutputStream os = noguiklient.sockRemoteScreen.getOutputStream();

Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
    Rectangle rectangle = new Rectangle(dim);  
    Robot robot = new Robot();                                            
BufferedImage image = robot.createScreenCapture(rectangle);

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();           

ImageIO.write(image, "jpg", byteArrayOutputStream);

byte[] size = 
ByteBuffer.allocate(4).putInt(byteArrayOutputStream.size()).array();            
int sizeas = ByteBuffer.wrap(size).asIntBuffer().get();

        os.write(size);
        os.write(byteArrayOutputStream.toByteArray());
        os.close();

客户端从服务器接收

JFrame okno = new JFrame();
    okno.setSize(1300, 1000);
    okno.setTitle(" Remote screen");
    okno.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    JPanel panel = new JPanel();
    panel.setSize(1300,1000);
    panel.setLayout(null);
    okno.add(panel);        
    okno.setVisible(true);


    InputStream is = Klient.sockRemoteScreen.getInputStream();
    File photo = new File ("photo") ;
    FileOutputStream fos = new FileOutputStream(photo);

    byte[] buffer = new byte[4];
    is.read(buffer);        
    int size = ByteBuffer.wrap(buffer).asIntBuffer().get();
    byte[] image = new byte [size];

    int count;
    int i =0 ;
    while((count = is.read(image)) > 0)
    {
        fos.write(image);
        fos.flush();

    }

       ImageIcon screen = new ImageIcon("photo");
       Image imagefinal = screen.getImage();                
       imagefinal = 
       imagefinal.getScaledInstance(okno.getWidth(),okno.getHeight(), Image.SCALE_SMOOTH);

       BufferedImage(width,height,BufferedImage.TYPE_INT_ARGB);
          Graphics graphics = panel.getGraphics();
while(true)
{
          graphics.drawImage(imagefinal, 0, 0, panel.getWidth(), panel.getHeight(), panel);     
}

Example of this bad Image

当我尝试使用ImageIO发送时，一切都很好但我想尝试使用字节并且存在问题。谢谢:)）
