Java后端利用百度地图全球逆地理编码，获取地址

声明：本人是在实习项目的时候遇到的问题

一.使用Api分为四步骤全球逆地理编码 rgc 反geo检索 | 百度地图API SDK

步骤1,2自行完成接下来去获取AK

二.申请AK

登录百度账号

点击创建应用，选择自己想用的服务，我只单选了逆地理编码，默认全选也是可以。

ip白名单自行设置，嫌麻烦可以设置为0.0.0.0/0，点击提交后拿到自己的AK

三.编写java代码

@Data
@Component
public class BaiduMapsUtils {private static final String API_KEY = "uCrrxBDB4bl76vh9B7F3vYfn3OVujUVd";private static final String REVERSE_GEOCODING_URL = "http://api.map.baidu.com/reverse_geocoding/v3/?ak=" + API_KEY + "&location=%s,%s&output=json";public static JsonNode reverseGeocode(Double  latitude, Double longitude) throws Exception {String urlString = String.format(REVERSE_GEOCODING_URL, latitude, longitude);URL url = new URL(urlString);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod("GET");connection.setRequestProperty("Accept", "application/json");if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));String inputLine;StringBuilder response = new StringBuilder();while ((inputLine = in.readLine()) != null) {response.append(inputLine);}in.close();connection.disconnect();ObjectMapper objectMapper = new ObjectMapper();JsonNode jsonNode = objectMapper.readTree(response.toString());return jsonNode;} else {return null;}}
}

    @RequestMapping("/api/index/positioning")public R getPositioning(@RequestParam(value = "longitude") Double longitude,@RequestParam(value = "latitude") Double latitude){JsonNode jsonNode = null;try{jsonNode = BaiduMapsUtils.reverseGeocode(longitude, latitude);}catch (Exception e){log.error("百度地图接口异常",e);}return R.data(jsonNode);}

简单编写了一段代码，代码不是唯一的，测试正常。
