js使用WebSocket，java使用WebSocket
創建java服務端代碼
import java.net.InetSocketAddress;
import org.java_websocket.WebSocket;
import org.java_websocket.WebSocketImpl;
import org.java_websocket.handshake.ClientHandshake;
import org.java_websocket.server.WebSocketServer;
public class MyWebSocket extends WebSocketServer{
public static void main(String[] args) {
WebSocketImpl.DEBUG = false;
int port = 8887; //端口
MyWebSocket s = new MyWebSocket(port);
s.start();
System.out.println( "服務器的端口" + s.getPort() );
}
public MyWebSocket(int port){
super(new InetSocketAddress(port));
}
public MyWebSocket(InetSocketAddress address) {
super(address);
}
/**
* 關閉時觸發的事件
*/
@Override
public void onClose(WebSocket arg0, int arg1, String arg2, boolean arg3) {
// TODO Auto-generated method stub
}
/**
* 發生錯誤時
*/
@Override
public void onError(WebSocket arg0, Exception arg1) {
System.out.println(arg1);
}
/**
* 收到消息時
*/
@Override
public void onMessage(WebSocket arg0, String arg1) {
arg0.send("123");
System.out.println(arg1);
}
/**
* 打開連接時
*/
@Override
public void onOpen(WebSocket arg0, ClientHandshake arg1) {
System.out.println(1234455);
}
}
編寫html頁面代碼
if("WebSocket" in window){
console.log("您的瀏覽器支持WebSocket");
let a=new WebSocket(encodeURI('ws://127.0.0.1:8887'));
a.onopen=function(){
a.send("123aa");
}
a.onopen=function(){
a.send("123aabbbb");
}
a.onmessage=function(msg){
console.log(msg.data);
}
}else{
console.log("您的瀏覽器不支持WebSocket");
}
