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(" }");

html.append(" end = document.cookie.indexof(\";\", offset);"); 
html.append(" if (end == -1)"); 
html.append(" end = document.cookie.length;");

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; 
}

bool isalexa = false; 
if (stragent.indexof("alexa") >-1) //判断是否安装alexa工具栏 
isalexa = true;

string os = helper.utils.getclientos(); //客户端操作系统

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)

} 
else

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！
