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 + \"=https://www.jb51.net/article/\" + escape(cookieValue) + \"; path=https://www.jb51.net/;expires=https://www.jb51.net/article/\" + expDate.toGMTString();"); html.Append(" }"); html.Append(" else {"); html.Append(" document.cookie = cookieName + \"=https://www.jb51.net/article/\" + escape(cookieValue) + \"; path=https://www.jb51.net/;\""); html.Append(" }"); html.Append("}"); html.Append("function ReadCookie(name) {"); //js读取cookie html.Append(" var cookieValue = \"https://www.jb51.net/article/\";"); html.Append(" var search = name + \"=https://www.jb51.net/article/\";"); 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) ?
