使用mob提供的接口 查询IP对应的省市区信息（json对象转java对象）
登录地址：http://api.mob.com
1、写一个发送请求的工具类
2、定义一个接受返回值的类
3、发送请求
---------这里是发送请求的工具类------------------

---------------------------------------
----------这里定义一个对象，接收返回值----------
package com.haochedai.bean;
/**
* Created by Administrator on 2017/5/26 0026.
*/
public class AreaBean {
private String city;
private String province;
public AreaBean() {
}
public AreaBean(String city, String province) {
this.city = city;
this.province = province;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getProvince() {
return province;
}
public void setProvince(String province) {
this.province = province;
}
}
-------------------------------
--------这里开始使用-----------

/**

*/
public class IpUtil {
static final org.slf4j.Logger LOGGER = LoggerFactory.getLogger(IpUtil.class);
private static final String URL = "http://apicloud.mob.com/ip/query?key=这里需要一个key值，需要自己去注册";
public static AreaBean getArea(String ip) {
if (StringUtils.isBlank(ip)) {
return new AreaBean();
}
JSONObject jsonObject = JSON.parseObject(HttpClientUtil.doGet(URL+"&ip="+ip));
String code = jsonObject.getString("retCode");
if (code.equals("200")) {
return jsonObject.getObject("result", AreaBean.class);
} else {
String msg = jsonObject.getString("msg");
LOGGER.error("IP地址解析异常: errorCode={}, msg={}", code, msg);
throw new PcsRunTimeException(msg);
}
}
// public static void main(String[] args) {
// System.out.println(IpUtil.getArea("112.27.205.106").getCity()+","+IpUtil.getArea("112.27.205.106").getProvince());
// }
}
