使用Java在HTTP上流式传输数据

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpStreamingExample {

        try {
            URL url = new URL(fileUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            BufferedInputStream inputStream = new BufferedInputStream(connection.getInputStream());
            BufferedOutputStream outputStream = new BufferedOutputStream(new FileOutputStream(savePath));

            byte[] buffer = new byte[4096];

            }

            outputStream.close();
            inputStream.close();
            connection.disconnect();

            System.out.println("File downloaded successfully.");
        } catch (IOException e) {
            e.printStackTrace();
