功能:實現客戶端和服務器端的聊天功能,目前只能從客戶端向服務器端單向發消息,對消息條數無限制
1、客戶端
import java.io.*;
import java.net.*;
import java.util.Scanner;
class TcpClient
{
public static void main(String[] args) throws Exception
{
Scanner sc = new Scanner(System.in);
String str = new String("start");
String endStr = new String("game over");
//創建客戶端的socket服務。指定目的主機和端口
Socket s = new Socket("10.11.2.251",10003);
//爲了發送數據,應該獲取socket流中的輸出流。
OutputStream out = s.getOutputStream();
while (!(str.equals(endStr)))
{
str = sc.nextLine();
out.write(str.getBytes());
}
s.close();
}
}
2、服務器端
class TcpServer {
public static void main(String[] args) throws Exception
{
String endStr = new String("bye bye");
//建立服務端socket服務。並監聽一個端口。
ServerSocket ss = new ServerSocket(10003);
Socket s = ss.accept();
String ip = s.getInetAddress().getHostAddress();
System.out.println(ip+".....connected");
//獲取客戶端發送過來的數據,那麼要使用客戶端對象的讀取流來讀取數據。
InputStream in = s.getInputStream();
byte[] buf = new byte[50];
in.read(buf);
String msgStr = new String(buf,"utf-8");
msgStr = msgStr.trim(); //去除字符串前後的空格
while (!(msgStr.equals(endStr)))
{
System.out.println(msgStr);
buf = new byte[buf.length];
in.read(buf);
msgStr = new String(buf,"utf-8");
msgStr = msgStr.trim();
}
System.out.println("bye bye\n聊天結束!");
ss.close();
s.close();//關閉客戶端.
}
}
