Java获取ip实际地址（区域，城市）

配合ip工具类和http工具类使用

public class AddressUtils {
          
   
	private static final Logger log = LoggerFactory.getLogger(AddressUtils.class);

	// IP地址查询
	public static final String IP_URL = "http://whois.pconline.com.cn/ipJson.jsp";

	// 未知地址
	public static final String UNKNOWN = "XX XX";

	public static String getRealAddressByIP(String ip) {
          
   
		String address = UNKNOWN;
		// 内网不查询
		if (IPUtils.internalIp(ip)) {
          
   
			return "内网IP";
		}
			try {
          
   
				//编码只能为GBK
				String rspStr = HttpUtils.sendGet(IP_URL, "ip=" + ip + "&json=true", "GBK");
				if (StringUtils.isEmpty(rspStr)) {
          
   
					log.error("获取地理位置异常 {}", ip);
					return UNKNOWN;
				}
				JsonObject obj = new JsonParser().parse(rspStr).getAsJsonObject();
				String region = obj.get("pro").getAsString();
				String city = obj.get("city").getAsString();
				return String.format("%s %s", region, city);
			} catch (Exception e) {
          
   
				log.error("获取地理位置异常 {}", e);
			}
		return address;
	}
