這兩天準備學習一下高德地圖API,因此在網上看了這篇博客,感受挺實用的,遂記錄下來,以便後續須要。內容部分沒有更改。java
public class GetLocation { public static String getAdd(String log, String lat) { // lat 小 log 大 // 參數解釋: 緯度,經度 type 001 (100表明道路,010表明POI,001表明門址,111能夠同時顯示前三項) 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; } public static void main(String[] args) { String add = getAdd("116.237191", "31.913839"); 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區:" + arr[2]); } } 須要注意的是JSONObject和JSONArray的引用是:import net.sf.json.JSONArray; import net.sf.json.JSONObject;
運行結果以下:json
