最近做一个项目,功能类似于CNZZ站长统计功能，要求显示Ip所在的省份市区/提供商等信息。
网上的Ip纯真数据库，下载下来一看，发现没提供商内容，省市区都很少，居然有XXX网吧，哥瞬间倒了。没标准化、并且杂乱、还不连续的IP段、总体说来没达到要求。
在百度上找啊找，找到淘宝Ip地址库，官方介绍的相当诱人,准确率高，数据质量有保障，提供国家、省、市、县、运营商全方位信息，信息维度广，格式规范，但是限制每秒10次的访问（这个比较无语）。
淘宝IP地址库,提供API http://ip.taobao.com/
接口说明
1. 请求接口（GET）：
http://ip.taobao.com/service/getIpInfo.php?ip=[ip地址字串]
2. 响应信息：
（json格式的）国家 、省（自治区或直辖市）、市（县）、运营商
3. 返回数据格式：
{"code":0,"data":{"ip":"210.75.225.254","country":"u4e2du56fd","area":"u534eu5317",
"region":"u5317u4eacu5e02","city":"u5317u4eacu5e02","county":"","isp":"u7535u4fe1",
"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",
"county_id":"-1","isp_id":"100017"}}
其中code的值的含义为，0：成功，1：失败。
1 ：IP转换
准备好工具,后面就好弄啦, IPHelper提供了各种,IP<->byte[]<->Long 转换
public class IPHelper
{
/// <summary>
/// ip转成long
/// </summary>
/// <param name="ip"></param>
/// <returns></returns>
public static long Ip2Long(string ip)
{
byte[] bytes = Ip2Bytes(ip);
return Bytes2Long(bytes);
}
/// <summary>
/// long转成ip
/// </summary>
/// <param name="ipLong"></param>
/// <returns></returns>
public static string Long2Ip(long ipLong)
{
byte[] bytes = Long2Bytes(ipLong);
return Bytes2Ip(bytes);
}
/// <summary>
/// long转成byte[]
/// </summary>
/// <param name="ipvalue"></param>
/// <returns></returns>
public static byte[] Long2Bytes(long ipvalue)
{
byte[] b = new byte[4];
for (int i = 0; i < 4; i++)
{
b[3 - i] = (byte)(ipvalue >> 8 * i & 255);
}
return b;
}
/// <summary>
/// byte[]转成long
/// </summary>
/// <param name="bt"></param>
/// <returns></returns>
public static long Bytes2Long(byte[] bt)
{
int x = 3;
long o = 0;
foreach (byte f in bt)
{
o += (long)f << 8 * x--;
}
return o;
}
/// <summary>
/// ip转成byte[]
/// </summary>
/// <param name="ip"></param>
/// <returns></returns>
public static byte[] Ip2Bytes(string ip)
{ // http://www.jbxue.com
string[] sp = ip.Split('.');
return new byte[] { Convert.ToByte(sp[0]), Convert.ToByte(sp[1]), Convert.ToByte(sp[2]), Convert.ToByte(sp[3]) };
}
/// <summary>
/// byte[]转成ip
/// </summary>
/// <param name="bytes"></param>
/// <returns></returns>
public static string Bytes2Ip(byte[] bytes)
{
return string.Format("{0}.{1}.{2}.{3}"
, bytes[0]
, bytes[1]
, bytes[2]
, bytes[3]);
}
}
2 ：多线程疯狂获取IP
/// <summary>
/// 描述:开始采集
/// </summary>
private void StratCollect()
{
foreach (Thread thread in ThreadList)
{
thread.Start();
}
}
/// <summary>
/// 描述:获取要采集的ip long
/// </summary>
private long GetCurrentIp()
{
long curip = System.Threading.Interlocked.Increment(ref CurrentCollectIP);
return curip;
}
/// <summary>
/// 线程中采集的方法
/// </summary>
private void GetTaobaoData()
{
long currentipLong = GetCurrentIp();
while (currentipLong <= EndIP)
{
try
{
CaptureTaobaoIPData(currentipLong);
}
catch (Exception ex)
{ // http://www.jbxue.com
TextLog.SetString(currentipLong + ex.Message);
}
currentipLong = GetCurrentIp();
}
}
/// <summary>
/// 描述:线程中采集并得到IP
/// </summary>
private void CaptureTaobaoIPData(long currentipLong)
{
string ip = IPHelper.Long2Ip(currentipLong);
string url = string.Format(UrlFomat, ip);
string js =HttpHelper. HttpRequest(url, Encoding.UTF8);
taobaoIPdata m = Newtonsoft.Json.JsonConvert.DeserializeObject<TaobaoJsonData>(js).data;
m.ipLong = currentipLong;
//更新界面
this.Invoke(new Action<taobaoIPdata>(v =>
{
taobaoIPdataList.Add(v);
this.dgv.DataSource = taobaoIPdataList;
}), m);
}
3： Http请求的Json结果，并反序列化成对象
http请求这个相当简单。网上一大把，这里主要说一下json序列化，在这里本人建议采用Newtonsoft.Json.dll 下载地址： http://json.codeplex.com/ 性能和兼容性达到最好
Http请求
public class HttpHelper
{
public static string HttpRequest(string url, Encoding encoding)
{
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Timeout = 6 * 1000;
request.Method = "GET";
//得到处理结果
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream myResponseStream = response.GetResponseStream();
StreamReader myStreamReader = new StreamReader(myResponseStream, encoding);
string result = myStreamReader.ReadToEnd();
return result;
}
catch (Exception ex)
{
throw ex;
}
}
}
Json序列化
taobaoIPdata m = Newtonsoft.Json.JsonConvert.DeserializeObject<TaobaoJsonData>(js).data;

4：插入到数据库中。。。剩下的自己随便搞啦
