我正在构建一个小型聊天应用程序,其中客户端A想要通过位于服务器B中间的方式将内容发送给客户端C。首先,这是否是解决问题的正确方法? 我能够向服务器发送和接收数据,但仅限于每个客户端。例如,如果客户端A向服务器B发送数据,客户端C也向服务器B发送数据,则我可以像回显服务器一样向A和C发送数据。但我想要的是将来自客户端A的数据通过服务器B转发到客户端C。
以下是服务器代码:
客户端代码如下:
以下是服务器代码:
public class Server {
public static void main(String[] args) {
int port = 666; //random port number
try {
ServerSocket ss = new ServerSocket(port);
System.out.println("Waiting for a client....");
System.out.println("Got a client :) ... Finally, someone saw me through all the cover!");
System.out.println();
while(true) {
Socket socket = ss.accept();
SSocket sSocket = new SSocket(socket);
Thread t = new Thread(sSocket);
t.start();
System.out.println("Socket Stack Size-----"+socketMap.size());
}
}
catch (Exception e) { }
}
}
class SSocket implements Runnable {
private Socket socket;
public SSocket(Socket socket) {
this.socket = socket;
}
@Override
public void run() {
try {
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
DataInputStream dIn = new DataInputStream(in);
DataOutputStream dOut = new DataOutputStream(out);
String line = null;
while (true) {
line = dIn.readUTF();
System.out.println("Recievd the line----" + line);
dOut.writeUTF(line + " Comming back from the server");
dOut.flush();
System.out.println("waiting for the next line....");
}
}
catch (Exception e) { }
}
}
客户端代码如下:
public class Client {
public static void main(String[] args) {
int serverPort = 666;
try {
InetAddress inetAdd = InetAddress.getByName("127.0.0.1");
Socket socket = new Socket(inetAdd, serverPort);
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
DataInputStream dIn = new DataInputStream(in);
DataOutputStream dOut = new DataOutputStream(out);
BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Type in something and press enter. Will send it to the server and tell ya what it thinks.");
System.out.println();
String line = null;
while (true) {
line = keyboard.readLine();
System.out.println("Wrinting Something on the server");
dOut.writeUTF(line);
dOut.flush();
line = dIn.readUTF();
System.out.println("Line Sent back by the server---" + line);
}
}
catch (Exception e) { }
}
}
