大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。
client码，如以下：
import java.io.*;
import java.net.*;
public class DailyAdviceClient {
public void go(){
try {
Socket s=new Socket("127.0.0.1",4242);//建立对server的Socket连接
//client从server读取数据
//建立连接到socket上低层输入串流的InputStreamReader
//InputStreamReader是低层和高层串流间的桥梁
//s.getInputStream()从Socket取得输入串流
InputStreamReader streamReader=new InputStreamReader(s.getInputStream());
//建立BufferedReader来读取
BufferedReader reader=new BufferedReader(streamReader);
String adviceString=reader.readLine();
System.out.println("Today you should: "+adviceString);
//client向server发送数据
//创建不带自己主动行刷新的PrintWriter对象。
//假设加入第二个參数true,则为自己主动刷新，不须要写writer.flush()这行代码
PrintWriter writer=new PrintWriter(s.getOutputStream());
writer.println("Hello,I am Client2!");
writer.flush();//刷新发送数据
System.out.println("此套接字连接的远程地址："+s.getInetAddress().getHostAddress());
System.out.println("此套接字绑定的本地地址："+s.getLocalAddress().getHostAddress());
System.out.println("此套接字绑定的本地端口:"+s.getLocalPort());
System.out.println("此套接字连接到的远程端口:"+s.getPort());
s.close();//关闭socket
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[]args){
DailyAdviceClient client=new DailyAdviceClient();
client.go();
}
}
server端代码例如以下：
import java.io.*;
import java.net.*;
public class DailyAdviceServer {
String[] adviceList={"Take smaller bites","One word: inappropriate",""
+ "Just for today,be honest","Tell your boss"};
public void go(){
try {
//服务器应用程序对特定port创建出ServerSocket对象
//这会让服务器应用程序监听来自4242port的client请求
ServerSocket serverSocket=new ServerSocket(4242);
//服务器进入无穷循环等待client的请求
while(true){
System.out.println("等待client连接...");
//接收到用户连接请求后。此方法会返回一个socket。以便于client通信
//此socket的port号和serverSocket的port号不同
Socket sock=serverSocket.accept();//此方法会堵塞直到有连接请求到达
System.out.println("此套接字连接的地址："+sock.getInetAddress().getHostAddress());
System.out.println("此套接字绑定的本地地址："+sock.getLocalAddress().getHostAddress());
System.out.println("此套接字绑定的本地port:"+sock.getLocalAddress());
System.out.println("此套接字连接到的远程port:"+sock.getPort());
//服务器向client发送数据
PrintWriter writer=new PrintWriter(sock.getOutputStream());
String adviceString=getAdvice();
writer.println(adviceString);
writer.flush();
System.out.println(adviceString);
//服务器接收client发送的数据
InputStreamReader streamReader=new InputStreamReader(sock.getInputStream());
BufferedReader reader=new BufferedReader(streamReader);
String adviceStringREC=reader.readLine();
System.out.println("REC: "+adviceStringREC);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String getAdvice(){
int random=(int)(Math.random()*adviceList.length);
return adviceList[random];
}
public static void main(String []args){
DailyAdviceServer server=new DailyAdviceServer();
server.go();
}
}
