一切从登录记录开始

看到之后，突然想去在登录环节也加上这个功能，然后就写了下面的具体实现代码。现在一点也不纠结了。

干货来了哦^_^

using System.Net;using System.Web;using Newtonsoft.Json;using System.Web.Script.Serialization;namespace ConsoleApplication1{    public class IPToLocation    {        public IPLocation GetLocationByTB(string ip)        {            if (string.IsNullOrEmpty(ip))                return null;            var webClient = new WebClient();            var entity = webClient.DownloadString(string.Format("http://ip.taobao.com/service/getIpInfo.php?ip={0}",ip));            var json = new JavaScriptSerializer().Deserialize
    
     (entity);            if (json == null || json["code"] == 1)                return GetLocationBySina(ip);    //调用其它接口            var data = new JavaScriptSerializer().Serialize(json["data"]);            IPLocation model = JsonConvert.DeserializeObject
     
      (data);            return model;        }        public IPLocation GetLocationBySina(string ip)        {            // http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip={0}            // 其它同上哦.        }    }    [JsonObject]    public class IPLocation    {        [JsonProperty]        public string IP { get; set; }        [JsonProperty]        public string Country { get; set; }        [JsonProperty]        public string Country_Id { get; set; }        [JsonProperty]        public string Area { get; set; }        [JsonProperty]        ...        ...    }}
