怎么利用IP地址查询归属地等具体信息

    

一、前言


    现在市面上有许多免费IP地址查询API接口,这里用的淘宝网的接口,其他接口也都大同小异,在项目中因为要多次用到这个接口,所以我把这个接口封装成了一个工具类,所用的语言是java。废话不多说,直接上代码:



二、具体代码实现

        String ip = "180.137.221.100";
        String address = "";
        try {
         address = AddressUtils.getAddresses(ip, "utf-8");
        } catch (UnsupportedEncodingException e) {
         e.printStackTrace();
        }
          System.out.println(address);
    }
    public static String getAddresses(String ip,String encodingString)throws UnsupportedEncodingException {
String content="ip="+ip;
// 这里调用pconline的接口
        String urlStr = "http://ip.taobao.com/service/getIpInfo.php";
        // 从http://whois.pconline.com.cn取得IP所在的省市区信息
        String returnStr = getResult(urlStr, content, encodingString);
        if (returnStr != null) {
            // 处理返回的省市区信息
            System.out.println("IP====="+returnStr);
            String[] temp = returnStr.split(",");

               switch (i) {

                    case 4:

                        region = decodeUnicode(region);            // 省份

                         break; 
                    case 7:
                      isp = (temp[i].split(":"))[1].replaceAll("\"", "");
                         isp = decodeUnicode(isp);                 // ISP公司
                         break;
               }
          }

            return address.toString();
        }
