一切从登录记录开始

看到TX的登录记录之后,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IP在数据库中保存类型是UNSIGNED INT还是VARCHAR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<dynamic>(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<IPLocation>(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]
        ...
        ...
    }
}
