我有一些简单的客户端和服务器代码,客户端向服务器发送一些字节,服务器用一些字节响应。客户端打印接收到的字节,然后关闭套接字。
这在客户端第一次运行时工作正常,但随后的调用没有响应。
package sockets.com;
// Client Side
import java.io.*;
import java.net.*;
public class ClientSideTCPSocket {
public void run() {
try {
int serverPort = 4023;
InetAddress host = InetAddress.getByName("localhost");
System.out.println("Connecting to server on port " + serverPort);
Socket socket = new Socket(host, serverPort);
System.out.println("Just connected to " + socket.getRemoteSocketAddress());
OutputStream out = socket.getOutputStream();
InputStream in = socket.getInputStream();
String s = "HELLO SERVER";
byte[] bytes = s.getBytes("US-ASCII");
for (byte b : bytes) {
out.write(b);
}
int ch = 0;
while ((ch = in.read()) >= 0) {
System.out.println("Got byte " + ch);
}
out.flush();
out.close();
socket.close();
} catch (UnknownHostException ex) {
ex.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
ClientSideTCPSocket client = new ClientSideTCPSocket();
client.run();
}
}
