Baidu Map API で、Java を使用して指定された場所の天気情報を取得するにはどうすればよいですか?

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class WeatherAPI {
    private static final String BASE_URL = "http://api.map.baidu.com/weather/v1/";
    private static final String AK = "your_access_key"; // 请替换成你自己的密钥

    public static void main(String[] args) {
        try {
            String location = "北京"; // 要查询的位置
            String encodedLocation = URLEncoder.encode(location, "UTF-8");
            String apiUrl = BASE_URL + "?location=" + encodedLocation + "&ak=" + AK;

            URL url = new URL(apiUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                StringBuilder response = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();

                System.out.println(response.toString());
            } else {
                System.out.println("HTTP请求失败，错误代码：" + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
