.Net Global.asax、httpModules伪静态功能实现

//第一种方法，Global文件重写

protected void Application_Start(object sender, EventArgs e)

{

File.AppendAllText(Server.MapPath("global.txt"),DateTime.Now.ToString()+" AppStart\r\n");

}

protected void Session_Start(object sender, EventArgs e)

{

File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString()+" ip:"+Request.UserHostAddress+ " SessionStart \r\n");

}

protected void Application_BeginRequest(object sender, EventArgs e)

{

//每次打开网页都会发生

//File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " ip:" + Request.UserHostAddress + "request\r\n");

////可以用来屏蔽指定ip

//if (HttpContext.Current.Request.UserHostAddress == "127.0.0.1")

//{

// HttpContext.Current.Response.Write("已被屏蔽");

// HttpContext.Current.Response.End();

//}

//防止图片盗链

if (HttpContext.Current.Request.Url.AbsolutePath.EndsWith(".jpg") && HttpContext.Current.Request.UrlReferrer.Host != "localhost")

{

//Context.Response.Write(HttpContext.Current.Request.UrlReferrer.Host);

HttpContext.Current.Response.WriteFile( HttpContext.Current.Server.MapPath("~/dl.jpg"));

HttpContext.Current.Response.End();

}

//符合格式时，内部重写，地址栏不显示此地址

Regex reg = new Regex(@".+MyStatic-(\d+).aspx");

var match = reg.Match(HttpContext.Current.Request.Url.AbsolutePath);

if(match.Success)

{

string page=match.Groups[1].Value;

//仿静态页面

HttpContext.Current.RewritePath("~/MyStatic.aspx?page="+page);

}



}

protected void Application_AuthenticateRequest(object sender, EventArgs e)

{

}

protected void Application_Error(object sender, EventArgs e)

{

//获取未处理的异常信息

Exception t = HttpContext.Current.Server.GetLastError();

File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() +t.Message+"服务器错误\r\n");

}

protected void Session_End(object sender, EventArgs e)

{

File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " ip:" + Request.UserHostAddress + " SessionEnd \r\n");

}

protected void Application_End(object sender, EventArgs e)

{

File.AppendAllText(Server.MapPath("global.txt"), DateTime.Now.ToString() + " AppEnd\r\n");

}

//第二种方法，建立类库（处理程序）重写url-处理任何请求

//类库handle里的类Myhandle

using System;

using System.Collections.Generic;

using System.Text;

using System.Web;

namespace handle

{

/// <summary>

/// 处理请求,添加引用System.Web

/// </summary>

class Myhandle:IHttpModule

{

public void Init(HttpApplication context)

{

context.BeginRequest += MyRequest;

}

public void Dispose()

{



}

protected void MyRequest(object sender, EventArgs e)

{

System.Web.HttpApplication app = (System.Web.HttpApplication)sender;

HttpContext context = app.Context;

HttpResponse response = context.Response;

string path = app.Context.Request.Path;

// app.Context.Response.Write(path);

string fname = System.IO.Path.GetFileName(path);

if (fname.Contains(".html"))

{

string pathWithOutFilename = path.Replace(fname, "");

System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex("([A-Za-z1-9]{1,})\\-(\\d+).html");

System.Text.RegularExpressions.Match match = reg.Match(fname);

if (match.Success)

{

//for (int i = 0; i < match.Groups.Count; i++)

// app.Context.Response.Write(match.Groups[i].Value+"<br/>");

path = "~" + pathWithOutFilename + match.Groups[1].Value + ".aspx?id=" + match.Groups[2].Value;

///http://localhost:6685/Read-14562.html

///转换成实际的 http://localhost:6685/Read.aspx?id=14562

context.RewritePath(path);

}

else

{

path = path.Replace(".do", ".aspx");

path = path.Replace(".html", ".aspx");

context.RewritePath("~" + path);

}

}

}

///网站项目中添加对该类库的引用

///Web.config文件中加入注册处理程序

//<httpModules>

// <add name="MyModule" type="handle.Myhandle,handle"/> ///加入这一句，handle为类库项目名，Myhandle为类名

// <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

//</httpModules>

}

IIS设置html由asp_net处理。。
