Android WebSocket 长连接推送

 

本地局网传送

第一步客户端

导入WebSocket jar包 implementation 'org.java-websocket:Java-WebSocket:1.3.0'

private WebSocketClient mSocketClient;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);

        init();

 handler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);

          wedTv.setText(wedTv.getText() + "\n" + msg.obj);
            }
        };
}

 

 

   private void init() {
        new Thread() {
            @Override
            public void run() {
                try {
                    Log.i("WebSocketClient_", "run_1111111");
                    mSocketClient = new WebSocketClient(new URI("ws://192.168.1.54:5478 "), new Draft_10()) {
                        @Override
                        public void onOpen(ServerHandshake handshakedata) {//打开通道
                            Log.i("WebSocketClient_", "onOpen_ 22222="+handshakedata);
                            handler.obtainMessage(0, handshakedata).sendToTarget();
                        }

                        @Override
                        public void onMessage(String message) {//接受服务器信息
                            Log.i("WebSocketClient_", "onMessage_ 3333="+message);
                            handler.obtainMessage(0, message).sendToTarget();

                        }

                        @Override
                        public void onClose(int code, String reason, boolean remote) {//通道关闭
                            Log.i("WebSocketClient_", "onClose_ 44444="+reason);
                            handler.obtainMessage(0, reason).sendToTarget();

                        }

                        @Override
                        public void onError(Exception ex) {
                            Log.i("WebSocketClient_", "onError_ 5554"+ex);

                        }
                    };
                    mSocketClient.connect();
                } catch (Exception e) {
                    e.printStackTrace();
                }

            }
        }.start();

    }

@OnClick({R.id.wed_bu})
    public void onViewClicked(View view) {
        switch (view.getId()) {

 

        case R.id.wed_bu:
                if (mSocketClient != null){
                  String str =  wedEt.getText().toString();
                    mSocketClient.send(str);
                }
                break;

}

@Override
    protected void onDestroy() {
        super.onDestroy();
        if (mSocketClient != null){
           mSocketClient.close();
        }
    }

客户端长连接发数据服务器接受，效果图

服务端接受客户端数据效果图

第二步服务端代码，服务器接受客户端数据，和服务器发送数据给客户端

导入包 implementation 'org.java-websocket:Java-WebSocket:1.3.0'

private static int PORT = 5478;
//telnet localhost  建立服务器
//ipconfig获取主机IP
//ping 拼接IP
public static void main(String[] arges) throws IOException  {

    /*-------WebSocket-------*/
    MWebSocketService socketServer = new MWebSocketService(PORT);
    socketServer.start();

    try {
        String ip = InetAddress.getLocalHost().getHostAddress();
        int port = socketServer.getPort();
        System.out.print(String.format("服务已启动: %s:%d", ip, port));
    } catch (UnknownHostException e) {
        e.printStackTrace();
    }

    InputStreamReader in = new InputStreamReader(System.in);
    BufferedReader reader = new BufferedReader(in);

    while (true){
        try {
            String msg = reader.readLine();
            socketServer.senToll(msg);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

创建一个MWebSocketService类

public class MWebSocketService  extends WebSocketServer {


    public MWebSocketService(int port) throws UnknownHostException {
        super(new InetSocketAddress(port));

    }
    public MWebSocketService(InetSocketAddress address) {
        super(address);
    }

    @Override
    public void onOpen(WebSocket webSocket, ClientHandshake clientHandshake) {
        String address = webSocket.getRemoteSocketAddress().getAddress().getHostAddress();
        String message = String.format("(%s) <进入房间！>", address);
        senToll(message);
        System.out.println(message);


    }

    @Override
    public void onClose(WebSocket webSocket, int code, String reason, boolean remote) {
        String address = webSocket.getRemoteSocketAddress().getAddress().getHostAddress();
        String message = String.format("(%s) <退出房间！>", address);
        senToll(message);
        System.out.println(message);

    }
    /**
     * 收到客户端消息后调用的方法
     *
     * @param //message 客户端发送过来的消息
     * @param
     */

    @Override
    public void onMessage(WebSocket webSocket, String s) {
        //服务端接收到消息
        String address = webSocket.getRemoteSocketAddress().getAddress().getHostAddress();
        String message = String.format("(%s) %s ",address,s);

        //将消息发送给所有客户端
        senToll("我是能能");//senToll方法是发数据给客户端
        System.out.print(message);

    }

    @Override
    public void onError(WebSocket webSocket, Exception e) {
        if (null != webSocket){
            webSocket.close();
        }
        e.printStackTrace();

    }
    public void senToll(String message){
        // 获取所有连接的客户端
        Collection connections = connections();
        //将消息发送给每一个客户端
        for (WebSocket client : connections ){
            client.send(message);
        }

    }
}
