Question

服务端接收到数据后怎么返回给客户端

Answer 1

这两个类，你拿去运行就好了
import java.io.*;
import java.net.*;
import java.util.Date;
public class Server {
public static void main(String[] args) throws Exception {
ServerSocket server = new ServerSocket(8888);
Socket socket = server.accept();
OutputStream os = socket.getOutputStream();
InputStream is = socket.getInputStream();
for(int i=0;i<9999;i++)is.read();
os.write(1);
is.close();
os.close();
socket.close();
server.close();
}
}
import java.io.*;
import java.net.*;
import java.util.Date;
public class Client {
public static void main(String[] args) throws Exception {
Socket socket = new Socket("127.0.0.1",8888);
OutputStream os = socket.getOutputStream();
InputStream is = socket.getInputStream();
long time1 = new Date().getTime();
for(int i=0;i<9999;i++)os.write(1);
is.read();
long time2 = new Date().getTime();
System.out.println(time1);
System.out.println(time2);
}
}

Answer 2

那就直接发，服务器端 直接利用客户端的IP 端口情况发送，客户端 可以接受
