java 根据经纬度获取地址实现代码

实现代码：

public class GetLocation { public static void main(String[] args) { // lat 39.97646 //log 116.3039 String add = getAdd("116.3039", "39.97646"); JSONObject jsonObject = JSONObject.fromObject(add); JSONArray jsonArray = JSONArray.fromObject(jsonObject.getString("addrList")); JSONObject j_2 = JSONObject.fromObject(jsonArray.get(0)); String allAdd = j_2.getString("admName"); String arr[] = allAdd.split(","); System.out.println("省："+arr[0]+"\n市："+arr[1]+"\n区："+arr[2]); } public static String getAdd(String log, String lat ){ //lat 小 log 大 //参数解释: 纬度,经度 type 001 (100代表道路，010代表POI，001代表门址，111可以同时显示前三项) String urlString = "http://gc.ditu.aliyun.com/regeocoding?l="+lat+","+log+"&type=010"; String res = ""; try { URL url = new URL(urlString); java.net.HttpURLConnection conn = (java.net.HttpURLConnection)url.openConnection(); conn.setDoOutput(true); conn.setRequestMethod("POST"); java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(conn.getInputStream(),"UTF-8")); String line; while ((line = in.readLine()) != null) { res += line+"\n"; } in.close(); } catch (Exception e) { System.out.println("error in wapaction,and e is " + e.getMessage()); } System.out.println(res); return res; } }
