如何使用jsoup (twitch)获取视频资源？

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.BufferedInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

public class TwitchVideoDownloader {

    public static void main(String[] args) {
        String url = "https://www.twitch.tv/example"; // Twitch视频页面的URL
        
        try {
            // 创建Jsoup连接并发起请求
            Document document = Jsoup.connect(url).get();
            
            // 定位视频资源元素
            Elements videoElements = document.select("video"); // 根据具体页面结构和需要进行选择
            
            // 获取视频链接
            String videoUrl = videoElements.attr("src"); // 根据具体页面结构和需要获取视频链接
            
            // 下载视频
            downloadVideo(videoUrl, "example.mp4"); // 保存到本地文件，根据具体需求进行处理
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    private static void downloadVideo(String videoUrl, String fileName) throws IOException {
        URL url = new URL(videoUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        
        // 获取视频流
        BufferedInputStream inputStream = new BufferedInputStream(connection.getInputStream());
        
        // 创建文件输出流
        FileOutputStream outputStream = new FileOutputStream(fileName);
        
        // 读取并保存视频文件
        byte[] buffer = new byte[4096];
        int bytesRead;
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
        }
        
        // 关闭流
        outputStream.close();
        inputStream.close();
        connection.disconnect();
    }
}
