Java 实例 – 获取 URL响应头的日期信息
Java 实例以下实例演示了如何使用 HttpURLConnection 的 httpCon.getDate() 方法来获取 URL响应头的日期信息：
Main.java 文件
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Date; public class Main{
public static void main(String args[])
throws Exception {
URL url = new URL("http://docs.gechiui.com/w3school");
HttpURLConnection httpCon =
(HttpURLConnection) url.openConnection();
long date = httpCon.getDate();
if (date == 0)
System.out.println("无法获取信息。");
else
System.out.println("Date: " + new Date(date));
}
}
import java.net.URL;
import java.util.Date; public class Main{
public static void main(String args[])
throws Exception {
URL url = new URL("http://docs.gechiui.com/w3school");
HttpURLConnection httpCon =
(HttpURLConnection) url.openConnection();
long date = httpCon.getDate();
if (date == 0)
System.out.println("无法获取信息。");
else
System.out.println("Date: " + new Date(date));
}
}
以上代码运行输出结果为：
