aps.net HttpModudel

使用HttpModudel  首先注册IHttpModudel  接口

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;





public class ModuleDemo : IHttpModule {





	// 声明一个事件

	public event EventHandler ExposedEvent;

	



	// Init方法仅用于给期望的事件注册方法

	public void Init(HttpApplication context) {

		context.BeginRequest += new EventHandler(context_BeginRequest);

	}



	// 处理BeginRequest 事件的实际代码

	void context_BeginRequest(object sender, EventArgs e) {

		HttpApplication application = (HttpApplication)sender;

		HttpContext context = application.Context;

		context.Response.Write("<h3 style='color:#00f'>来自HttpModule的处理，请求到达</h3><hr>");

		

		OnExposedEvent(new EventArgs());

	}

	

	protected virtual void OnExposedEvent(EventArgs e) {

		if (ExposedEvent != null)	// 如果Global中有注册

			ExposedEvent(this, e);	// 调用注册了的方法

	}

	

	public void Dispose() {

	}

}

然后在webconfig 注册该HttpModule   注册如下:

 

<httpModules>

			<add name="MyModule" type="ModuleDemo"/>

 

获取查看  HttpModule 

ublic partial class RegisteredModules : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

		 Response.Write(ShowModules());

    }





	private string ShowModules() {

		HttpApplication app = Context.ApplicationInstance; //获取当前上下文的HttpApplication环境

		HttpModuleCollection moduleCollection = app.Modules; //获取所有Module集合



		// 获取所有的 Module 名称

		string[] moduleNames = moduleCollection.AllKeys;



		System.Text.StringBuilder results = new System.Text.StringBuilder();





		//遍历结果集

		foreach (string name in moduleNames) {

			results.Append("<b style='color:#800800'>名称：" + name + "</b><br />");	// 获得Module名称

			results.Append("类型：" + moduleCollection[name].ToString() + "<br />");	// 获得Module类型

		}



		return results.ToString();

	}



}
