如何解析url以获得文件名？

from urllib.parse import urlparse

url = "https://example.com/path/to/file.txt"
parsed_url = urlparse(url)
path = parsed_url.path
file_name = path.split("/")[-1]
print(file_name)

const { URL } = require('url');

const url = new URL('https://example.com/path/to/file.txt');
const path = url.pathname;
const file_name = path.split("/").pop();
console.log(file_name);

import java.net.URI;
import java.net.URISyntaxException;

public class Main {
    public static void main(String[] args) {
        try {
            URI uri = new URI("https://example.com/path/to/file.txt");
            String path = uri.getPath();
            String file_name = path.substring(path.lastIndexOf('/') + 1);
            System.out.println(file_name);
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }
}
