由于工作需要,最近将其urchin.js的代码down了一份下来研究了一下.由于其注释很少,命名也很难读懂.研究了1个月.小有所成.将其代码重写并加上了注释.与大家一同分享.这里面将google的用户识别代码删除.

但是最终传输的时候是以分隔符的形式传递给服务器端的.
GUID为随机数,google是这么做的.当初没有想通为什么要保存一个随机数,后来分析数据的才明白过来.为了验证用户的唯一性.

function GetResidentTime() { pageClose = new Date(); minutes = (pageClose.getMinutes() - pageOpen.getMinutes()); if(minutes < 0) { minutes = minutes + 60; } seconds = (pageClose.getSeconds() - pageOpen.getSeconds()); if(seconds < 0){ seconds += 60;} time = (seconds + (minutes * 60)); //------------------------修改此处为接收链接地址 XML 异步传输------------------------------------// var xmlHttp = createXMLHttpRequest();// xmlHttp.open("POSt", reqURL + firstvisit.aspx?" + StrPara(), false);// xmlHttp.send(null);//----------------------------图片形式传递------------------------------------------------------- if(isReturn() == false) { var i = new Image(1,1); i.src = reqURL + "firstVisit.aspx?" + StrPara() + "&GUID=" + GUID; i.onload = function() {LoadVoid();} //进入页面的信息 if(getCookieValue("GUID") == "noCookie"){return ;} i.src = reqURL + "pageView.gif?" + pageView() + "&st=" + time; i.onload=function() {LoadVoid();} } else { var i=new Image(1,1); i.src = reqURL + "pageView.gif?" + pageView() + "&st=" + time; i.onload=function() {LoadVoid();} }}传递的参数大家可以打印出来看一下.应该可以明白其意思.
剩下的就是服务器端的处理了,在服务器端处理其实相当简单.取得request的值,验证并保存入数据库.现在有了数据,分析的事情就由用户按照自己的要求来处理了..补充一句,ip地址是由服务器端来取得保存的.
使用的时候记得一定将其放到服务器端,然后使用<javascript language="javascript" type="text/javascript" src=服务器地址+路径+"statistics.js"> </script> 附上完整的代码https://files.cnblogs.com/BlackSoul/statistic.rar下载.
