using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web; using System.Text.RegularExpressions; namespace MyMook { public class MyHttpModule : IHttpModule { public void Dispose() { } public void Init(HttpApplication application) { application.AcquireRequestState += new EventHandler(context_AcquireRequestState); // application.BeginRequest += new EventHandler(context_AcquireRequestState); //这里面要注意千万不要写成BeginRequest，那样就会无法获得session } void context_AcquireRequestState(Object source, EventArgs e) { HttpApplication application = (HttpApplication)source; HttpContext context = application.Context; string path=context.Request.Path; if (!context.Request.CurrentExecutionFilePathExtension.Equals(".aspx") && !context.Request.CurrentExecutionFilePathExtension.Equals(".ashx") ) { return; }//此处保证只过滤aspx/ashx/htm的请求 Match m = Regex.Match(path,@"/WebLogin/+"); if (m.Success) { return; }//不过滤文件夹WebLogin中的内容 try { object user = context.Session["user"]; if (user == null) { context.Response.Redirect("~/WebLogin/Login.aspx"); } else { return; } } catch { context.Response.Redirect("~/WebLogin/Login.aspx"); } } } } |
在web.config中：
|
1 2 3 4 5 |
<system.webServer> <modules> <add name="<span class="attribute-value">MyHttpModule"</span> <span class="attribute">type</span>=<span class="attribute-value">"MyMook.MyHttpModule,MyMook</span>"/> </modules> </system.webServer> |
要点：
1.注册事件时，不要写application.BeginRequest，这样会导致无法获得Session.

application.AcquireRequestState += new EventHandler(context_AcquireRequestState); // application.BeginRequest += new EventHandler(context_AcquireRequestState); |
