java 根据经纬度获取地址实现代码

 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;
}
}
