我正在尝试进行简单的聊天。我有一个处理更多客户端的服务器。这是我到目前为止所做的:连接,我可以在我的服务器上识别哪个客户端正在发送消息,但问题是在客户端上我无法像在服务器上那样得到完整的对话。例如
Client_1 (writing)
msg : hi
Client_2 (writing)
msg : hi from cl2
results
Server :
Client_1 : hi
Client_2 : hi from cl2
Client_1
Client_1 : hi
Client_2
Client_2 :hi from cl2
我希望实现两个客户端都具有与服务器相同的信息。
My Server Script :
public class Server {
public static void main(String[] args) throws IOException {
ServerSocket server = new ServerSocket(1900);
System.out.println("waiting");
while (true) {
Socket sock = server.accept();
System.out.println("Client nou conectat !");
ClientHandler cH = new ClientHandler(sock);
cH.start();
}
}
}
class ClientHandler extends Thread {
BufferedReader in;
PrintWriter out;
ClientHandler(Socket sock) throws IOException {
out = new PrintWriter(new OutputStreamWriter(sock.getOutputStream()),
true);
in = new BufferedReader(new InputStreamReader(sock.getInputStream()));
}
public void run () {
try {
out.println("Hello from server"); //hello message to client
while (true) {
String linie = in.readLine();
if (linie==null)
return;
System.out.println(linie); //message from client
out.println(linie);
}
}catch(Exception e) {e.printStackTrace();}
}
}
客户端脚本
public class Client {
public static void main(String[] args) throws Exception {
// String ip ="192.168.1.12";
String ip ="localhost";
Socket sock = new Socket(ip, 1900); // localhost daca ii pe
// acelasi pc serverul
// si clientul,altfel
// IPul
PrintWriter out = new PrintWriter(new OutputStreamWriter(
sock.getOutputStream()), true);
BufferedReader in = new BufferedReader(new InputStreamReader(
sock.getInputStream()));
String linie = in.readLine();
System.out.println("Server :" + linie);//meesage from server
BufferedReader console = new BufferedReader(new InputStreamReader(
System.in));
while (true) {
linie = console.readLine();
out.println("Client_1 :"+linie); // sending to server
String linie2 =in.readLine();
System.out.println(linie2); //resend message to client
}
}
}
我希望我能很好地解释我的问题:D。感谢所有人的建议
答案 0 :(得分:1)
在您的服务器端。
您为服务器的每个客户端连接创建一个ClientHandler,这是好的,然后读取来自每个ClientHandler的内容。
但是每个ClientHandler都与服务器上有多少其他客户端无关,你必须“连接它们”。
我会创建一个
public class ClientDispatcher{
private List<ClientHandler> clients;
}
并通知ClientDispatcher ClientHandler拥有的每条消息,以便他可以将消息“发送”给其他人。
