在Java中以HTTP格式获取日期

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class HttpDateExample {
    public static void main(String[] args) {
        LocalDateTime now = LocalDateTime.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEE, dd MMM yyyy HH:mm:ss zzz");
        String httpDate = now.format(formatter);
        System.out.println("HTTP Date: " + httpDate);
    }
}
