在Java程式設計中,如何與Web伺服器連線?
以下範例演示如何使用net.Socket
類的sock.getInetAddress()
方法與Web伺服器連線。
package com.yiibai;
import java.net.InetAddress;
import java.net.Socket;
public class Connected2Server {
public static void main(String[] args) {
try {
InetAddress addr;
Socket sock = new Socket("www.tw511.com", 80);
addr = sock.getInetAddress();
System.out.println("Connected to " + addr);
sock.close();
} catch (java.io.IOException e) {
System.out.println("Can't connect to " + args[0]);
System.out.println(e);
}
}
}
上述程式碼範例將產生以下結果 -
Connected to www.tw511.com/112.124.103.85
