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<WebSocket> connections = connections();
//将消息发送给每一个客户端
for (WebSocket client : connections ){
client.send(message);
}
}
}服务器长连接发数据给客户端接受效果图
