ASP.NET MVC 3实现访问统计系统

运营网站，我们经常需要分析用户的行为、用户的习惯，用户看重网站的哪一部分，哪一部分是对用户有用的之类的信息，这些信息从哪里来，这时我们就需要用到访问统计系统了。 网上已经有很多的统计系统，如站长统计、百度统计、谷歌分析之类的，别人的东西始终是别人的，为什么我们不自己实现统计的功能呢，而且自己写的可以实现一些特殊的功能，如登录，下单行为，能够更好的融合自己的系统！

下面我们就用ASP.NET MVC 3来实现一个访问统计系统！首先，使用程序生成一段js代码，包括读写Cookie，及写入一个唯一值到Cookie中，用来判断独立访客者，再写入访问次数及上一个访问页面ID值；然后就是获取客户端时间，分辨率之类的。

string guid = Guid.NewGuid().ToString(); 
#region 生成js 
html.Append("function WriteCookie(cookieName, cookieValue, expiry) {"); //js写cookie 
html.Append(" var expDate = new Date();"); 
html.Append(" if (expiry) {"); 
html.Append(" expDate.setTime(expDate.getTime() + expiry);"); 
html.Append(" document.cookie = cookieName + \"=\" + escape(cookieValue) + \"; path=/;expires=\" + expDate.toGMTString();"); 
html.Append(" }"); 
html.Append(" else {"); 
html.Append(" document.cookie = cookieName + \"=\" + escape(cookieValue) + \"; path=/;\""); 
html.Append(" }"); 
html.Append("}"); 
html.Append("function ReadCookie(name) {"); //js读取cookie 
html.Append(" var cookieValue = \"\";"); 
html.Append(" var search = name + \"=\";"); 
　html.Append(" if (document.cookie.length >0) {"); 
html.Append(" offset = document.cookie.indexOf(search);"); 
html.Append(" if (offset != -1) {"); 
html.Append(" offset += search.length;"); 
html.Append(" end = document.cookie.indexOf(\";\", offset);"); 
html.Append(" if (end == -1)"); 
html.Append(" end = document.cookie.length;"); 
html.Append(" cookieValue = unescape(document.cookie.substring(offset, end))"); 
html.Append(" }"); 
html.Append(" }"); 
html.Append(" return cookieValue;");

html.Append(" sparetime = 1000 * 60 * 60 * 24 * 3650;"); //有效期为一年

html.Append(" HBCountShowCookie = ReadCookie(\"HBCountShowCookie\");");

生成之后再去执行下一个Action，用来写入一些统计数据，如客户端IP，浏览器信息，访问页面来源，当前页、访问时间、离开时间等！根据上一个访问页面地址、当前地址及上一个访问页面ID来判断是否是刷新操作还是新的访问页面，如果是刷新操作则写入刷新时间，否则写入上一个页面的离开时间，由于js的跨域问题，

if (assort.Equals(0)) 
{ 
ly = Request.QueryString["Ly"]; //获取来源URL 
currWeb = Request.QueryString["CurrWeb"]; //获取当前URL 
} 
else 
{ 
ly = Request.ServerVariables["Http_Referer"]; 
currWeb = ly; 
} 
string firstShow = Request.QueryString["FirstShow"]; //是否第一次访问 
string visitTotal = Request.QueryString["VisitTotal"]; //获取浏览次数 
string ip = Helper.Utils.ClientIP(); //获取客户端IP地址 
string strAgent = Request.ServerVariables["HTTP_USER_AGENT"]; 
bool isAlexa = false; 
if (strAgent.IndexOf("alexa") >-1) //判断是否安装alexa工具栏 
isAlexa = true; 
string browerName = Request.Browser.Browser; //浏览器名称 
string browerVersion = Request.Browser.Version; //浏览器版本 
string os = Helper.Utils.GetClientOS(); //客户端操作系统

if (!string.IsNullOrEmpty(spider))
