我正在尝试在运行以下代码的 chrome 扩展之间建立 websocket 连接:

if('WebSocket' in window){
  connect('ws://localhost:8181/chat');
}

function connect(host) {
  var ws = new WebSocket(host);
  ws.onopen = function () {
    alert('connected');
  };

  ws.onmessage = function (evt) {  
    alert('reveived data:'+evt.data);
  };

  ws.onclose = function () {
    alert('socket closed');
  };
};

和一个 Java 服务器。

import java.io.*;
import java.net.*;
import java.util.logging.Level;
import java.util.logging.Logger;

public class ServerThread extends Thread {
    Socket socket = null;
    int NumberOfThread;
    Main Mainthread;

    public ServerThread(Socket socket) {
    super("ServerThread");
    this.socket = socket;
    }




    @Override
    public void run(){

        try {
            while(true){


            BufferedReader SS_BF = new BufferedReader(new             InputStreamReader(socket.getInputStream()));


            String temp = SS_BF.readLine();
            System.out.println(temp);



            }

       } catch (IOException ex) {

           suicide();
        }

}

public void suicide(){
    try {

        /*this.socket.shutdownInput();
        this.socket.shutdownOutput();

        this.socket.close();*/

        Mainthread.Coroner(NumberOfThread);

    } catch (IOException ex) {
        Logger.getLogger(ServerThread.class.getName()).log(Level.SEVERE, null, ex);
    }
}
public void identify(int n, Main m)throws IOException{

    NumberOfThread=n;
    Mainthread=m;

}
public void Send(String s)throws IOException{
    PrintStream SSPS = new PrintStream(socket.getOutputStream());
    SSPS.println(s);
    System.out.println ("Sent text to CLIENT_" + NumberOfThread);
}
}

所以我可以建立连接,直到握手,然后什么也没有。客户端挂起或断开连接,但永远不会触发 onOpen 事件。

我希望我已经提供了足够的信息。谁能告诉我如何从 google chrome 扩展程序中的客户端和在桌面上运行的 java 服务器建立 websocket 连接?

提前致谢!斯莫列特。
