java 对接高德地图，通过经纬度获取当前定位的代码

以下是 Java 对接高德地图，通过经纬度获取当前定位的代码示例：

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

public class Location {

    public static void main(String[] args) {
        try {
            String url = "http://restapi.amap.com/v3/geocode/regeo?key=您的key&location=经度,纬度&poitype=&radius=1000&extensions=all&batch=false&roadlevel=0";
            // 经度和纬度需要替换成实际的值
            url = url.replace("经度", "116.481488").replace("纬度", "39.990464");
            String result = sendGet(url);
            System.out.println(result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static String sendGet(String url) throws Exception {
        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();

        con.setRequestMethod("GET");

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        return response.toString();
    }
}

其中，key 是高德地图开放平台申请的开发者 Key，location 是经纬度信息，poitype 是搜索类型，radius 是搜索半径，extensions 是返回结果的扩展信息，batch 是批量查询，roadlevel 是道路等级。具体参数含义可以参考高德地图开放平台的文档。
