Springboot利于第三方服务进行ip定位获取省份城市等信息

在web应用的开发中，我们或许会想知道我们的用户请求的来源分布情况。本文基于springboot框架，调用百度地图、高德地图的开放平台api，在线对对请求来源的ip进行定位、解析，获取目标ip所对应的省份、城市、经纬度等信息，方便开发者将相关数据记录在操作日志中。

一. 共用部分

统一响应类

/**

 */










@Data





@Builder
public class IpAnalyzeResponse {

    /**
     * 状态码
     */

    private String status;


    /**
     * 是否成功
     */
    private Boolean successFlag;



    /**


     * 失败原因
     */


    private String msg;


    /**

     * 省份名称
     */

    private String province;



    /**

     * 城市名称
     */

    private String city;


    /**

     * 经度
     */


    private Double x;


    /**

     * 维度
     */

    private Double y;
}

定义接口

实现该接口，并在配置类中注入接口的实现类，即可拓展ip定位的更多实现方式

/**











 * @author 摆渡人










 * @description ip定位接口
 * @date 2023/7/13 23:25
 */










public interface IPlatFormIpAnalyzeService {

    /**
     * ip定位解析
     * @param ip
     * @return
     */

    IpAnalyzeResponse ipAnalyze(String ip);
}

public class IpAnalyzePoint implements Serializable {








    private String x;


    private String y;
}

3.实现接口`IPlatFormIpAnalyzeService`

/**











 * @author 摆渡人










 * @description 百度地图开发平台实现类
 * @date 2023/7/10 20:27
 */










@Slf4j


public class PlatformBaiduService implements IPlatFormIpAnalyzeService {








    /**





     * 响应成功状态码

     */





    private final Integer OK_CODE = 0;







    @Value("${platform.conf.baidu.ak}")
    public String ak;


    @Override

    public IpAnalyzeResponse ipAnalyze(String ip) {

        String URL = "http://api.map.baidu.com/location/ip";
        Map<String,String> params = new HashMap<>();

        params.put("ip", ip);
        params.put("ak", ak);
        params.put("coor", "bd09ll");
        try {
            String json = SmartHttpUtil.sendGet(URL, params, null);
            IpAnalyzeBaiduResponse response = JSONUtil.toBean(json, IpAnalyzeBaiduResponse.class);
            if(OK_CODE.equals(response.getStatus())) {
                return IpAnalyzeResponse.builder()
                        .status(response.getStatus() + "")

                        .y(Double.parseDouble(response.getContent().getPoint().getY()))
                        .build();
            }
            return IpAnalyzeResponse.builder()
                    .status(response.getStatus() + "")
                    .successFlag(false)
                    .msg(response.getMessage())
                    .build();
        } catch (Exception e) {
            return IpAnalyzeResponse.builder()
                    .status("500")
                    .successFlag(false)
                    .msg(e.getMessage())
                    .build();
        }
    }
}

三.高德地图开放平台实现

1. 使用准备

根据文档获取Key-创建工程-开发指南-Web服务 API|高德地图API (amap.com)指引获取key

2. 封装实体类

/**











 * @author 摆渡人










 * @description 高德地图ip定位响应类
 * @date 2023/7/14 0:00
 */










@Data





public class IpAnalyzeGaodeResponse {








    /**





     * 返回结果状态值,值为0或1,0表示失败；1表示成功
     */





    private String status;







    /**



     * 返回状态说明，status为0时，info返回错误原因，否则返回“OK
     */



    private String info;


    /**

     * 返回状态说明,10000代表正确,详情参阅info状态表
     */

    private String infocode;



    /**

     * 若为直辖市则显示直辖市名称；
     *
     * 如果在局域网 IP网段内，则返回“局域网”；
     *

     */
    private String province;

    /**
     * 若为直辖市则显示直辖市名称；
     *
     * 如果为局域网网段内IP或者非法IP或国外IP，则返回空
     */


    private String city;


    /**

     * 城市的adcode编码
     */

    private String adcode;

    /**
     * 所在城市矩形区域范围，所在城市范围的左下右上对标对，如：116.0119343,39.66127144;116.7829835,40.2164962
     */
    private String rectangle;
}

3.实现接口`IPlatFormIpAnalyzeService`

/**











 * @author 摆渡人










 * @description 高德地图开放平台ip定位实现类
 * @date 2023/7/13 23:56
 */










@Slf4j


public class PlatformGaodeService implements IPlatFormIpAnalyzeService {








    /**





     * 响应成功状态码

     */





    private final String OK_CODE = "1";







    @Value("${platform.conf.gaode.key}")
    private String key;


    @Override

    public IpAnalyzeResponse ipAnalyze(String ip) {

        String URL = "https://restapi.amap.com/v3/ip";
        Map<String,String> params = new HashMap<>();

        params.put("key",key);
        params.put("ip",ip);
        try {
            String json = SmartHttpUtil.sendGet(URL, params, null);
            IpAnalyzeGaodeResponse response = JSONUtil.toBean(json, IpAnalyzeGaodeResponse.class);
            if(OK_CODE.equals(response.getStatus())) {
                IpAnalyzeResponse ipAnalyzeResponse = IpAnalyzeResponse.builder()
                        .status(response.getInfocode())
                        .successFlag(true)
                        .msg(response.getInfo())
                        .province(response.getProvince())
                        .city(response.getCity())
                        .build();
                // 对rectangle进行解析
                String rectangle = response.getRectangle();
                String[] split = rectangle.split(";|,");
                if(split.length == 1) {
                    ipAnalyzeResponse.setSuccessFlag(false);
                    ipAnalyzeResponse.setStatus("0");
                    ipAnalyzeResponse.setMsg("ip[" + ip + "]非法");
                    return ipAnalyzeResponse;
                }
                ipAnalyzeResponse.setX((Double.parseDouble(split[0]) + Double.parseDouble(split[2])) / 2.0);
                ipAnalyzeResponse.setY((Double.parseDouble(split[1]) + Double.parseDouble(split[3])) / 2.0);
                return ipAnalyzeResponse;
            }
            return IpAnalyzeResponse.builder()
                    .status(response.getInfocode())
                    .successFlag(false)
                    .msg(response.getInfo())
                    .build();
        } catch (Exception e) {
            e.printStackTrace();
            return IpAnalyzeResponse.builder()
                    .status(“500”)
                    .successFlag(false)
                    .msg(e.getMessage())
                    .build();
        }
    }
}

四. 使用

1.配置参数

# 第三方开放平台的服务
platform:
  # 目前支持百度[baidu] 高德[gaode]
  mode: # 您选择的服务
  # 相关配置
  conf:
    # 百度
    baidu:
      ak: # 您的百度地图开放平台服务密钥（AK）
    # 高德
    gaode:
      key: # 您的高德地图开放平台key

2.配置类

根据配置参数中platform.mode的值选择接口IPlatFormIpAnalyzeService的一个服务类注入Spring容器中去

/**











 * @author 摆渡人










 * @description 接口实现类配置
 * @date 2023/7/14 0:16
 */










@Configuration
public class PlatFormConfig {








    @Bean
    @ConditionalOnProperty(prefix = "platform",name = "mode",havingValue = "baidu")
    public IPlatFormIpAnalyzeService initBaiduIpAnalyzeService() {
        return new PlatformBaiduService();
    }


    @Bean
    @ConditionalOnProperty(prefix = "platform",name = "mode",havingValue = "gaode")
    public IPlatFormIpAnalyzeService initGaodeIpAnalyzeService() {
        return new PlatformGaodeService();
    }
}

3.单元测试

/**











 * @author 摆渡人










 * @description 
 * @date 2023/7/14 0:23
 */










@Slf4j


@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class PlatformTest {


     @Autowired
    private IPlatFormIpAnalyzeService platFormIpAnalyzeService;







     @Test
     public void testIpAnalyzeService() {
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze(null));
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze(""));
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze("127.0.0.1"));
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze("114.247.50.2"));
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze("219.137.148.0"));
         log.info("解析结果：{}",platFormIpAnalyzeService.ipAnalyze("114.80.166.240"));
     }



}

运行结果如下：

platform.mode=gaode
