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
...
{
public class Class1:System.Web.IHttpModule
...{ public void Init(HttpApplication application) ...{ application.PreSendRequestHeaders += new EventHandler(application_PreSendRequestHeaders);
} void application_PreSendRequestHeaders(object sender, EventArgs e) ...{ HttpApplication Application = (HttpApplication)sender; HttpContext context = Application.Context; if (context.Response.StatusCode == 302) ...{ context.Response.Write("<script>window.open('"+context.Response.RedirectLocation+"')</script>"); context.Response.StatusCode = 200; } } public void Dispose() ...{ } }
}
最后配置一下web.config就可以了
<?
xml version="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>Object moved</title></head><body>
"
);
this
.Write(
"
<h2>Object moved to <a href="
"
+
HttpUtility.HtmlAttributeEncode(url)
+
"
">here</a>.</h2>
"
);
this
.Write(
"
</body></html>
"
);
