如何將byte []寫入IoSession

Question

如下圖所示，我可以讀取IoSession發送的字節[]，而不需要協議解碼器。

IoBuffer in = (IoBuffer) message; 
byte[] inBytes = in.array(); 
int length = inBytes[0]; 
inBytes = Arrays.copyOfRange(inBytes, 1, length + 1); 
ByteString incomingMessage = ByteString.copyFrom(inBytes); 

但是當我嘗試這樣做：

someIoSession.write(incomingMessage.toByteArray()); 

我碰到下面的錯誤。

Don't know how to handle message of type XXXX. Are you missing a protocol encoder?

我怎麼能只寫字節到IoSession？

Answer 1

someIoSession.write(IoBuffer.wrap(incomingMessage.toByteArray()));
