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;  
  } 
   
}
