Response.Redirect在新窗口打开的另一种方法

这里是孟子提供的方法

这里介绍Ihttpmodule处理请求管道的方法。Response.Redirect的原理是服务器设置返回http状态码为302,然后客户端执行跳转,用reflector可以看到.net的代码段。

以下是HttpResponse类的Redirect方法中的跳转代码

this .StatusCode = 0x12e ;
this .RedirectLocation = url;

所以,我们可以扩展Ihttpmodule来拦截http状态码,强制设为200,同时插入js代码段来实现新窗口打开。以下是Ihttpmodule的实现代码

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
namespace ClassLibrary2
... {
publicclassClass1:System.Web.IHttpModule
...{
publicvoidInit(HttpApplicationapplication)
...{

application.PreSendRequestHeaders
+=newEventHandler(application_PreSendRequestHeaders);
}


voidapplication_PreSendRequestHeaders(objectsender,EventArgse)
...{
HttpApplicationApplication
=(HttpApplication)sender;

HttpContextcontext
=Application.Context;

if(context.Response.StatusCode==302)
...{
context.Response.Write(
"<script>window.open('"+context.Response.RedirectLocation+"')</script>");
context.Response.StatusCode
=200;
}


}


publicvoidDispose()
...{
}



}

}

最后配置一下web.config就可以了

<? xmlversion="1.0" ?>
< configuration >
< system .web >
< compilation debug ="true" />
< authentication mode ="Windows" />
< httpModules >
< add name ="MyModule" type ="ClassLibrary2.Class1,ClassLibrary2" ></ add >
</ httpModules >
</ system.web >
</ configuration >

另外一点,ms自坐主张的在跳转之后,end之前插入了这么一段代码,我得b4他们一下,解决办法,大家自己想想吧。

this .Write( " <html><head><title>Objectmoved</title></head><body> " );
this .Write( " <h2>Objectmovedto<ahref=" " + HttpUtility.HtmlAttributeEncode(url) + " ">here</a>.</h2> " );
this .Write( " </body></html> " );
