在百度地图API中，如何使用Java获取指定位置的静态地图图片？

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;

public class BaiduMapAPIExample {
    public static void main(String[] args) {
        String location = "39.988563,116.473176"; // 指定的位置（纬度,经度）
        int width = 400; // 图片宽度
        int height = 300; // 图片高度
        int zoom = 15; // 缩放级别
        String apiKey = "your_api_key"; // 替换成你的API Key

        String requestUrl = "http://api.map.baidu.com/staticimage/v2?ak=" + apiKey
                + "&center=" + location + "&width=" + width + "&height=" + height + "&zoom=" + zoom;

        try {
            URL url = new URL(requestUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setConnectTimeout(5000); // 设置连接超时时间
            connection.setReadTimeout(5000); // 设置读取超时时间

            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                InputStream inputStream = connection.getInputStream();
                FileOutputStream outputStream = new FileOutputStream("map.png"); // 图片保存路径
                byte[] buffer = new byte[1024];
                int len;
                while ((len = inputStream.read(buffer)) != -1) {
                    outputStream.write(buffer, 0, len);
                }
                outputStream.close();
                inputStream.close();
                System.out.println("静态地图图片下载完成！");
            } else {
                System.out.println("请求失败：" + responseCode);
            }
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
