服务器 - 客户端聊天程序

Question

我正在写一个服务器 - 客户端聊天程序.

这是我的代码

服务器:

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class HelloServer {

    public final static int defaultPort = 2345;

    public static void main(String[] args) {
        int port = defaultPort;
        try {
            port = Integer.parseInt(args[0]);
        } catch (Exception e) {
        }
        if (port <= 0 || port >= 65536) {
            port = defaultPort;
        }
        try {
            ServerSocket ss = new ServerSocket(port);

            while (true) {
                try {
                    Socket s = ss.accept();

                    String response = "Hello " + s.getInetAddress() + " on port " + s.getPort()
                            + "\r\n";
                    response += "This is " + s.getLocalAddress() + " on port " + s.getLocalPort()
                            + "\r\n";
                    OutputStream out = s.getOutputStream();
                    out.write(response.getBytes());
                    System.out.write(response.getBytes());
                    InputStream in = s.getInputStream();

                    System.out.println("from client");
                    int z = 0;
                    while ((z = in.read()) != -1) {
                        System.out.write(z);
                    }

                } catch (IOException e) {
                }
            }
        } catch (IOException e) {
            System.err.println(e);
        }
    }
}

客户:

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class SocketGetINetAdd {

    public static void main(String[] args) throws UnknownHostException, IOException {
        Socket socket = new Socket("192.xxx.x.xxx", 2345);
        InetAddress inetAddress = socket.getInetAddress();

        System.out.println("Connected to:: " + inetAddress.getHostName() + " Local address:: "
                + socket.getLocalAddress() + " Local Port:: " + socket.getLocalPort());
        BufferedInputStream bfINPUT = new BufferedInputStream(socket.getInputStream());
        int b = 0;
        OutputStream os = System.out;
        while ((b = bfINPUT.read()) != -1) {
            os.write(b);
        }
        OutputStream osNew = socket.getOutputStream();
        String s = "This Is The Client"; // data to be sent
        osNew.write(s.getBytes());
        os.write(s.getBytes());

}

我通过我的程序连接了它们.

但现在我想知道如何从客户端将一些数据发送回服务器？

什么是客户端的代码(用于向服务器发送数据)以及用于显示从控制台(服务器)上的客户端接收的数据的服务器的代码？

PS-我是网络编程的新手.请不要批评我的编码风格:P

Answer 1

使用服务器流

OutputStream os = socket.getOutputStream();

而不是客户端控制台输出流

OutputStream os = System.out;

在客户端写回服务器.

并且在服务器端使用客户端流以相同的方式从客户端读取.

InputStream in = s.getInputStream();

我已经在服务器 - 客户端通信上发布了示例代码.阅读它是为了你的学习.
