通过淘宝接口免费获取IP地址信息

1.获取互联网访问IP信息

    一般获取互联网访问的IP的相关信息一般都是收费接口，免费的接口不多，我使用到一个接口如下：

　　

http://ip.taobao.com/service/getIpInfo.php?ip=139.189.109.174

这个是淘宝的接口，直接可以查询对应的IP信息，免费使用哦。在Java程序里可以直接封装调用。

对封装获取IP的地址的方法代码如下：

HttpRequestUtils.java

package com.seezoon.framework.common.context.exception;

public class ServiceException extends RuntimeException {

    public ServiceException() {
        super();
        // TODO Auto-generated constructor stub
    }

    public ServiceException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
        // TODO Auto-generated constructor stub
    }

    public ServiceException(String message, Throwable cause) {
        super(message, cause);
        // TODO Auto-generated constructor stub
    }

    public ServiceException(String message) {
        super(message);
        // TODO Auto-generated constructor stub
    }

    public ServiceException(Throwable cause) {
        super(cause);
        // TODO Auto-generated constructor stub
    }

}

调用使用方法如下：

if (StringUtils.isNotEmpty(ip)) {
                    String ipInfo = HttpRequestUtils.doGet("http://ip.taobao.com/service/getIpInfo.php", Maps.newHashMap("ip",ip));
                    if (StringUtils.isNotEmpty(ipInfo)) {
                        JSONObject parseObject = JSON.parseObject(ipInfo);
                        if (parseObject.containsKey("data")) {
                            JSONObject data = parseObject.getJSONObject("data");
                            System.out.println(data.getString("region") + data.getString("city"));
                        }
                    }
                }
