TCP 简单

1、

Client 连接 Server ：

        InetSocketAddress endpoint = new InetSocketAddress(FstrDestIP , FstrDestPort); 
        
        Socket Fsock = new Socket();//(FstrDestIP, 445);
        Fsock.connect(endpoint, 1000);
        Fsock.setTcpNoDelay(true); //关闭Nagle算法.立即发包
        */
        //设置发送逗留时间2秒 //中断后未传输数据可传输的时间（秒）,defalut false
        //socket.setSoLinger(true, 2); 
        //设置InputStream上调用 read()阻塞超时时间2秒 
        //socket.setSoTimeout(2000); 

2、

接收消息 ：

    @Override
    public void run()
    {
        //super.run();
        
        System.out.println("Thread in .");
        try
        {
            InputStream is = Fsock.getInputStream();
            while (true)
            {
                byte[] bytesRecv = new byte[1024];
                int iRecvLen = is.read(bytesRecv);
                if ((iRecvLen == 0) || (-1 == iRecvLen))
                {
                    System.out.println("Thread out (1)");
                    break; // 退出循环
                }
                
                for (int i=0; i<iRecvLen; i++)
                {
                    System.out.println(bytesRecv[i]+" ");
                }
            } // while
            is.close();
            Fsock.close();
            System.out.println("Thread out (2)");
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }

3、

发送信息：

    public void SendBytes(byte[] _bytesSend) throws Exception
    {
        OutputStream os = Fsock.getOutputStream(); 
        os.write(_bytesSend);
    }
