4.1地理编码查询

public class TiandituAPICallExample2 {public static void main(String[] args) {// 创建 RestTemplate 实例RestTemplate restTemplate = new RestTemplate();try {// 构建 URLString baseUrl = "http://api.tianditu.gov.cn/geocoder";UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(baseUrl).queryParam("ds", "{\"keyWord\":\"北京市朝阳区酒仙桥路甲10号\"}").queryParam("tk", "你自己的key");String url = builder.toUriString();// 发送 GET 请求并获取响应ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);String responseBody = response.getBody();// 打印响应结果System.out.println(responseBody);} catch (Exception e) {e.printStackTrace();}}
}

结果

封装获取地理坐标

public static Map<String,String> getCoordinate(String address) {// 创建 RestTemplate 实例RestTemplate restTemplate = new RestTemplate();try {// 构建 URLString baseUrl = "http://api.tianditu.gov.cn/geocoder";UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(baseUrl).queryParam("ds", "{\"keyWord\":\""+address+"\"}").queryParam("tk", "你自己的key");String url = builder.toUriString();// 发送 GET 请求并获取响应ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);int statusCodeValue = response.getStatusCodeValue();if (statusCodeValue == 200) { // 表示成功String responseBody = response.getBody();// 创建 JsonReader 对象JsonReader jsonReader = Json.createReader(new StringReader(responseBody));// 解析 JSON 响应为 JsonObjectJsonObject jsonObject = jsonReader.readObject();// 关闭 JsonReaderjsonReader.close();// 访问解析后的值JsonObject locationObj = jsonObject.getJsonObject("location");//坐标点显示经度double lon = locationObj.getJsonNumber("lon").numberValue().doubleValue();//坐标点显示纬度double lat = locationObj.getJsonNumber("lat").numberValue().doubleValue();Map map = new HashMap();map.put("lon",lon);map.put("lat",lat);return map;}} catch (Exception e) {e.printStackTrace();}return null;}

 

4.2逆地理编码查询

通过坐标获取地理信息

public static String getAddress(Double lon, Double lat, String tk){String postStr = "{'lon':"+lon+",'lat':"+lat+",'ver':1}";String apiUrl = "http://api.tianditu.gov.cn/geocoder?postStr="+postStr+"&type=geocode&tk="+tk+"";StringBuilder response = null;try {// 创建 URL 对象URL url = new URL(apiUrl);// 打开连接HttpURLConnection connection = (HttpURLConnection) url.openConnection();// 设置请求方法为 GETconnection.setRequestMethod("GET");// 获取响应状态码int responseCode = connection.getResponseCode();System.out.println("Response code: " + responseCode);// 读取响应内容BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));response = new StringBuilder();String line;while ((line = reader.readLine()) != null) {response.append(line);}reader.close();// 关闭连接connection.disconnect();} catch (IOException e) {e.printStackTrace();}return response.toString();}
