Java根据百度API获得经纬度，然后根据经纬度在获得城市信息详解编程语言

* @author jueyue 返回格式：Map String,Object map map.put("status", * reader.nextString());//状态 map.put("result", list);//查询结果 * list map String,String * 密钥:f247cdb592eb43ebac6ccd27f796e2d2 public class GetLatAndLngByBaidu { /** * @param addr * 查询的地址 * @return * @throws IOException public Object[] getCoordinate(String addr) throws IOException { String lng = null;//经度 String lat = null;//纬度 String address = null; try { address = java.net.URLEncoder.encode(addr, "UTF-8"); }catch (UnsupportedEncodingException e1) { e1.printStackTrace(); String key = "f247cdb592eb43ebac6ccd27f796e2d2"; String url = String .format("http://api.map.baidu.com/geocoder?address=%s output=json key=%s", address, key); URL myURL = null; URLConnection httpsConn = null; try { myURL = new URL(url); } catch (MalformedURLException e) { e.printStackTrace(); InputStreamReader insr = null; BufferedReader br = null; try { httpsConn = (URLConnection) myURL.openConnection();// 不使用代理 if (httpsConn != null) { insr = new InputStreamReader( httpsConn.getInputStream(), "UTF-8"); br = new BufferedReader(insr); String data = null; int count = 1; while((data= br.readLine())!=null){ if(count==5){ lng = (String)data.subSequence(data.indexOf(":")+1, data.indexOf(","));//经度 count++; }else if(count==6){ lat = data.substring(data.indexOf(":")+1);//纬度 count++; }else{ count++; } catch (IOException e) { e.printStackTrace(); } finally { if(insr!=null){ insr.close(); if(br!=null){ br.close(); return new Object[]{lng,lat};
public static void main(String[] args) throws IOException { GetLatAndLngByBaidu getLatAndLngByBaidu = new GetLatAndLngByBaidu(); Object[] o = getLatAndLngByBaidu.getCoordinate("成都市天府四街"); System.out.println(o[0]);//经度 System.out.println(o[1]);//纬度 }

输出结果：104.04701

  30.548397

 

调用以下路径根据经纬度获取地址，返回数据为JSON格式，

http://api.map.baidu.com/geocoder/v2/?ak=pmCgmADsAsD9rEXkqWNcTzjd location=30.548397,104.04701 output=json pois=1

返回结果：
