使用MongoDB存储访问者信息

网站的访问者信息的存储一般都是海量的,通常使用关系数据库,现在NoSQL运动火热,满足这样的需求使用NoSQL数据库会更好,网站访问者信息主要是两个功能:

1、记录下网站的访问者信息

2、查询访问者信息和做相关的数据分析

本文采用MongoDB来记录访问者的信息的示例:

在asp.net中记录访问者信息的方法可以通过一个HttpHandler,在页面上放一个1像素的图片来请求这个HttpHandler,把他放到MasterPage页面就可以了。

下面给出ashx的代码

   1: public class a : IHttpHandler
   2: {
   3:     public void ProcessRequest(HttpContext ctx)
   4:     {
   5:         HttpBrowserCapabilities bc = ctx.Request.Browser;
   6:         Stat stat = new Stat();
   7:         stat._id = Guid.NewGuid();
   8:         stat.Browser = bc.Browser;
   9:         stat.Type = bc.Type;
  10:         stat.Version = bc.Version;
  11:         stat.Platform = bc.Platform;
  12:         stat.UrlReferrer = ctx.Request.UrlReferrer.ToString();
  13:         stat.UserHostAddress = ctx.Request.UserHostAddress;
  14:         stat.HttpMethod = ctx.Request.HttpMethod;
  15:         stat.IsAuthenticated = ctx.Request.IsAuthenticated;
  16:         stat.LogDateTime = DateTime.Now.ToLocalTime();
  17:  
  18:         WebClient wc=new WebClient();
  19:         try
  20:         {
  21:             string s =
  22:                 wc.DownloadString("http://ipinfodb.com/ip_query.php?ip=" + stat.UserHostAddress + "&output=xml");
  23:             XmlDocument doc = new XmlDocument();
  24:             doc.LoadXml(s);
  25:             stat.Country = doc.DocumentElement.SelectNodes("CountryCode")[0].InnerText;
  26:             stat.State = doc.DocumentElement.SelectNodes("RegionName")[0].InnerText;
  27:  
  28:             stat.City = doc.DocumentElement.SelectNodes("City")[0].InnerText;
  29:             stat.Latitude = doc.DocumentElement.SelectNodes("Latitude")[0].InnerText;
  30:             stat.Longitude = doc.DocumentElement.SelectNodes("Longitude")[0].InnerText;
  31:             
  32:         }
  33:         catch(Exception ex)
  34:         {
  35:             System.Diagnostics.Debug.WriteLine(ex.Message+ ex.StackTrace );
  36:         }
  37:         finally
  38:         {
  39:             wc.Dispose();
  40:         }
  41:         using (Mongo mongo = Mongo.Create(Helper.ConnectionString()  ))
  42:         {
  43:             MongoCollection<Stat> coll = (MongoCollection<Stat>)mongo.GetCollection<Stat>();
  44:             coll.Save(stat);
  45:         }
  46:        
  47:         string sFileName = String.Empty;
  48:         string sPath = ctx.Server.MapPath(".");
  49:         try
  50:         {
  51:             sFileName = ctx.Request["name"].ToString().Trim();
  52:             if (sFileName.Length < 5) { return; }  // must be at least "1.gif" (5 chars)
  53:             // serve the image that was requested:
  54:             ctx.Response.WriteFile(sPath + @"\" +  sFileName);
  55:         }
  56:         catch (Exception e)
  57:         {
  58:  
  59:             ctx.Response.Write(e.Message);
  60:         }
  61:     }
  62:     public bool IsReusable { get { return true; } }
  63: }

上面代码使用到了HttpBrowserCapabilities,这里可以得到客户端的浏览器信息。还有客户端ip的来源使用到了ipinfodb.com这个服务,IPinfoDB网站非常的慷慨,慷慨到让人惊讶的程度,除了提供给你XML APIJSON API调用外,还提供了实现这些API的source code和所有的IP数据库,也就是说你只要下载这份code和database你也可以架设一个和IPinfoDB一样的网站,一样能够提供API服务,不过国外做的IP数据库对国内来说肯定不是很全很准,不过先将就着用吧。

访问访问者信息的MongoDB的信息记录:

   1: [Serializable]
   2: public class Stat
   3: {
   4: [MongoIdentifier]
   5: public Guid _id {get;set;}
   6: public string Type {get;set;}
   7: public string Browser {get;set;}
   8: public string Version {get;set;}
   9: public string Platform {get;set;}
  10: public string UrlReferrer {get;set;}     
  11: public string UserHostAddress  {get;set;}
  12: public bool IsAuthenticated {get;set;}
  13: public string HttpMethod  {get;set;}
  14: public DateTime LogDateTime { get; set; }
  15: public string City { get; set; }
  16: public string State { get; set;}
  17: public string Country { get; set; }
  18: public string Latitude { get; set; }
  19: public string Longitude { get; set; }
  20: }

然后利用MongoDB的C# NORm驱动记录到MongoDB。
