在IIS 7中可以轻松实现文件下载次数统计
在IIS 6中要实现文件下载统计,我知道的只有两个方法:
1、自己写ISAPI Filters。
2、通过通配符映射,将所有文件映射到ASP.NET运行时,然后在ASP.NET程序中统计下载次数,还要处理文件下载。
在IIS 7中,实现这个功能很轻松:
写一个HttpModule:
using System;
using System.Web;
namespace cnblogs
{
/// <summary>
/// Summary description for DownloadCountModule
/// </summary>
public class DownloadCounterModule : IHttpModule
{
public DownloadCounterModule()
{
}
#region IHttpModule Members
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.PreSendRequestContent += new EventHandler(context_PreRequestHandlerExecute);
}
void context_PreRequestHandlerExecute(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
string url = context.Request.RawUrl;
//文件下载统计代码
}
#endregion
}
}
using System.Web;
namespace cnblogs
{
/// <summary>
/// Summary description for DownloadCountModule
/// </summary>
public class DownloadCounterModule : IHttpModule
{
public DownloadCounterModule()
{
}
#region IHttpModule Members
public void Dispose()
{
}
public void Init(HttpApplication context)
{
context.PreSendRequestContent += new EventHandler(context_PreRequestHandlerExecute);
}
void context_PreRequestHandlerExecute(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
HttpContext context = app.Context;
string url = context.Request.RawUrl;
//文件下载统计代码
}
#endregion
}
}
然后在IIS 7的Modules中增加(Add Managed Module)这个Module就行了。
