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("}");
html.Append("DateFormatString = function(datetime, format) {");
html.Append(" var year = datetime.getFullYear();");
html.Append(" var month = datetime.getMonth()+1;");
html.Append(" var date = datetime.getDate();");
html.Append(" var hour = datetime.getHours();");
html.Append(" var minutes = datetime.getMinutes();");
html.Append(" var second = datetime.getSeconds();");
html.Append(" format = format.replace(/YY/g, year).replace(/MM/g, month).replace(/DD/g, date).replace(/hh/g, hour).replace(/mm/g, minutes).replace(/ss/g, second);");
html.Append(" return format;");
html.AppendLine("}");
html.Append("var cookieEnabled = (navigator.cookieEnabled) ? true : false;"); //判断浏览器是否支持cookie
html.Append("if (typeof navigator.cookieEnabled == \"undefined\" &&!cookieEnabled) {");
html.Append(" document.cookie = \"testcookie\";");
html.Append(" cookieEnabled = (document.cookie == \"testcookie\") ? true : false;");
html.Append(" document.cookie = \"\";");
html.Append("}");
html.Append("var firstshow;");
html.Append("var visittotal;");
　html.Append("var isLogin;");
html.Append("var loginName;");
html.Append("if (cookieEnabled == true) {");
html.Append(" var HBCountShowCookie = ReadCookie(\"HBCountShowCookie\");"); //访客浏览器唯一ID
html.Append(" var HBCountVisitTotalCookie = ReadCookie(\"HBCountVisitTotalCookie\");"); //访客浏览次数
html.Append(" var HBClientIDCookie = ReadCookie(\"HBClientIDCookie\");"); //访客上一个点击页面ID
html.Append(" var HBLoginNameCookie = ReadCookie(\"HBLoginNameCookie\");"); //记录登录的用户名
html.Append(" if (HBCountShowCookie == \"\") {");
html.Append(" sparetime = 1000 * 60 * 60 * 24 * 3650;"); //有效期为一年
html.Append(" WriteCookie('HBCountShowCookie', \"" + guid + "\", sparetime);");
html.Append(" HBCountShowCookie = ReadCookie(\"HBCountShowCookie\");");
html.Append(" firstshow = 1;");
html.Append(" }");
html.Append(" else {");
html.Append(" firstshow = 0;");
html.Append(" }");
html.Append(" if (HBCountVisitTotalCookie == \"\") {"); //游客统计
html.Append(" sparetime = 1000 * 60 * 60 * 24 * 3650;");
html.Append(" WriteCookie('HBCountVisitTotalCookie', 1, sparetime);");
html.Append(" visittotal = 1;");
html.Append(" }");
html.Append(" else {");
html.Append(" if (firstshow == 1) {");
html.Append(" visittotal = parseInt(HBCountVisitTotalCookie) + 1;");
html.Append(" sparetime = 1000 * 60 * 60 * 24 * 3650;");
html.Append(" WriteCookie('HBCountVisitTotalCookie', visittotal, sparetime);");
html.Append(" }");
html.Append(" else {");
html.Append(" visittotal = parseInt(HBCountVisitTotalCookie);");
html.Append(" }");
html.Append(" }");
html.Append(" try {");
html.Append(" if (HBStat != undefined || HBStat.isLogin != undefined || HBStat.loginName != undefined) {"); //此为登录用户统计

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
string langage = Helper.Utils.GetLangage(); //客户端语言
string spider = Helper.Utils.GetSpiderBot(); //搜索引擎爬虫信息
bool isSpider = false;
if (!string.IsNullOrEmpty(spider))
isSpider = true;
HttpContext.Application.Lock();
ClickDataAccess clientBasic = new ClickDataAccess();
　//刷新操作 需要根据上一个地址和当前地址 来判断
if (HttpContext.Application["HBCurrWeb_" + SiteID] != null
&&HttpContext.Application["HBCurrWeb_" + SiteID].ToString().Equals(currWeb)
&&HttpContext.Application["HBLy_" + SiteID] != null
&&HttpContext.Application["HBLy_" + SiteID].ToString().Equals(ly)
&&HttpContext.Application["HBClientId_" + SiteID] != null)
{
clientBasic.UpdateForRefresh(HttpContext.Application["HBClientId_" + SiteID]);
//Helper.Utils.CreateFile("~/Log/", DateTime.Now.ToString("yyyyMMddHHmmssffff") + "_" + SiteID + "刷新.txt", writetext.ToString());
}
else
{
if (HttpContext.Application["HBClientId_" + SiteID] != null) //如果存在上一个页面的ID值则写入离开时间
clientBasic.UpdateForLeaveTime(HttpContext.Application["HBClientId_" + SiteID]);
ClickAndVisitorsDataAccess clientData = new ClickAndVisitorsDataAccess();
string[] outParam = clientData.Save(client);
if (!string.IsNullOrEmpty(outParam[0]))
HttpContext.Application["HBPublicId_" + SiteID] = outParam[0];
if (!string.IsNullOrEmpty(outParam[1]))
{
HttpContext.Application["HBClientId_" + SiteID] = outParam[1];
javaScript = "WriteCookie('HBClientIDCookie'," + int.Parse(outParam[1]) + ");";
}
HttpContext.Application["HBCurrWeb_" + SiteID] = currWeb;
HttpContext.Application["HBLy_" + SiteID] = ly;
}
HttpContext.Application.UnLock();

这里使用Application来存储对象，当然也可以使用缓存类来做.

暂时没有解决离开当前网站时的离开时间，当然如果访问统计系统的域名和被统计的网站域名是同一个*域名，则可以做到这点！

访问统计系统的后台使用存储过程来统计分析数据，暂时只写了一部分功能，仅供大家学习参考！
