如何从微软图形API下载文件(InputStream)？

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class FileDownloader {
    public static void main(String[] args) {
        String fileUrl = "https://example.com/file.pdf"; // 文件的URL地址

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

            // 获取文件的InputStream
            InputStream inputStream = new BufferedInputStream(connection.getInputStream());

            // TODO: 处理文件的InputStream，可以保存到本地文件或者进行其他操作

            // 关闭连接和InputStream
            inputStream.close();
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
