网站流量统计

本程序采用.net平台和mysql数据库实现
mysql数据库中表：

CREATE TABLE `web_statistics` (
 `id` int(10) unsigned NOT NULL auto_increment,
 `Cur_url` varchar(500) NOT NULL,
 `Pre_url` varchar(500) NOT NULL default '未知',
 `Os` varchar(50) NOT NULL default '未知',
 `Ip` varchar(15) NOT NULL,
 `Browser` varchar(50) NOT NULL default '未知',
 `Access_Time` datetime NOT NULL,
 `Host_Name` varchar(45) NOT NULL default '未知',
 PRIMARY KEY  (`id`)
)

mysql存储过程：

CREATE  PROCEDURE `proc_statistics`(Cur_url varchar(500),Pre_url varchar(500),Os varchar(50),Brows varchar(50),Host_Name varchar(45),Ip varchar(15))
begin
insert into web_statistics(Cur_url,Pre_url,Os,Ip,Browser,Access_Time,Host_Name)
values(Cur_url,Pre_url,Os,Ip,Brows,now(),Host_Name);
end

实现调用：
因为我把本程序部署在dag.wzu.edu.cn域名的服务器上，所以可以直接通过html+js代码就可以实现客户端的访问统计功能

<img  style="width:0px;height:0px;border:0px" id="statistics_id_fei" /><script type="text/javascript"> window.onload = function () { document.getElementById("statistics_id_fei").src = "http://dag.wzu.edu.cn/statistics.ashx?d="+ encodeURI(document.referrer).replace('&', '`') + "&u=" + encodeURI(document.location.href).replace('&', '`') + "&x=" + Math.random(); }</script>

说明：
1、在执行文件ashx上，采用了多种可选方式，其中数据库方面有直接拼接sql，sql参数方法，存储过程调用三种方法；
2、为了能够是js中的onload事件能够执行，加载完ashx文件后，生成一个对应的图片文件，采用了直接加载cache缓存方式实现；
3、只要直接把这里的html和js代码复制到你网址的直接的任何地方就可以实现自己站点的访问量统计。
