如何在java中使用HTTP url获取远程服务器目录的所有文件名？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class GetRemoteDirectoryFiles {
    public static void main(String[] args) {
        try {
            // 创建URL对象
            URL url = new URL("http://example.com/remote_directory/");
            
            // 打开URL连接
            URLConnection connection = url.openConnection();
            
            // 设置请求属性
            connection.setRequestProperty("User-Agent", "Mozilla/5.0");
            
            // 获取输入流
            InputStream inputStream = connection.getInputStream();
            
            // 读取输入流中的数据
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            String line;
            while ((line = reader.readLine()) != null) {
                // 解析出文件名
                String fileName = line.substring(line.lastIndexOf(">") + 1, line.lastIndexOf("<"));
                System.out.println(fileName);
            }
            
            // 关闭输入流和连接
            reader.close();
            inputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
