a端发送Message

WebSocket mConnecttion=new WebSocketConnection();mConnecttion.connect(wsUri, new WebSocketConnectionHandler(){                @Override                    public void onOpen() {                        Log.d("MessageSender.start.open", "open");                        mConnecttion.sendTextMessage(msg);                        super.onOpen();                    }                    @Override                    public void onClose(int code, String reason) {                        Log.d("MessageSender.start.close", "close");                        super.onClose(code, reason);                    }                    @Override                    public void onTextMessage(String payload) {                        Log.d("MessageSender.start.textMessage", "textMessage");                        super.onTextMessage(payload);                    }                });

wsUrl的格式是：ws://192.168.8.29:8088/

b端接受Message

public class WebSocket extends NanoWebSocketServer{    public WebSocket(int port) {        super(port);    }    public WebSocket(String hostname, int port) {        super(hostname, port);    }    @Override    public WebSocket openWebSocket(IHTTPSession handshake) {        Log.d("WebSocket .openWebSocket", "openWebSocket");        return super.openWebSocket(handshake);    }    //受到消息    @Override    protected void onFrameReceived(WebSocketFrame webSocket) {        webSocket.getTextPayload();        Log.d("WebSocket .onFrameReceived", webSocket.getTextPayload());        super.onFrameReceived(webSocket);    }    @Override    public void onSendFrame(WebSocketFrame webSocket) {        Log.d("WebSocket .onSendFrame", "onSendFrame");        super.onSendFrame(webSocket);    }    @Override    protected void onClose(WebSocket arg0, CloseCode arg1, String arg2,            boolean arg3) {        Log.d("WebSocket .onClose", "onClose");    }    @Override    protected void onException(WebSocket arg0, IOException arg1) {        Log.d("WebSocket .onException", "onException");        arg1.printStackTrace();    }    @Override    protected void onMessage(WebSocket arg0, WebSocketFrame arg1) {        Log.d("WebSocket .onMessage", "onMessage");    }    @Override    protected void onPong(WebSocket arg0, WebSocketFrame arg1) {        Log.d("WebSocket .onPong", "onPong");    }}

a端可以发送自己的ip和端口信息到b端，同时在a端用NanoHTTPD实现小型的服务器，然后b端可以通过http请求访问a端，实现通信。
NanoHTTPD服务：

public class WebService extends NanoHTTPD{    public WebService(int port) {        super(port);    }    public WebService(String hostname, int port) {        super(hostname, port);    }    @Override    public Response serve(IHTTPSession session) {        Log.d("WebService.session.url",session.getUri());        if(session.getUri().equals("http://192.168.8.250:9000/image")){            try {                InputStream input=new StringBufferInputStream("我发的就是这么没意义！");                return newChunkedResponse(Status.OK,"image",input);            } catch (Exception e) {                             e.printStackTrace();            }        }        return super.serve(session);    }}

b端的Http请求：
