using System;
using System.Web;
namespace _515xiao
{
    public class UrlWriter : IHttpModule
    {
        HttpApplication _application = null;
        #region IHttpModule 成员
        public void Dispose() { }
        public void Init(HttpApplication context)
        {
            context.BeginRequest += new EventHandler(context_BeginRequest);
            _application = context;
        }
        void context_BeginRequest(object sender, EventArgs e)
        {
            string requesturl = _application.Context.Request.Path.ToLower().Replace("http://www.515xiao.cn",string.Empty).Replace(".aspx", string.Empty);
            string[] listparam = requesturl.Split(new char[] { '_' });
            if (listparam.Length > 1 && listparam[0] == "/list")
            {
                string firstname = listparam[1];
                if (Reg.RegString.IsInt(firstname))
                    _application.Context.RewritePath("~/list.aspx?lid=" + firstname);
            }
            if (listparam.Length > 1 && listparam[0] == "/search")
            {
                string firstname = listparam[1];
                    _application.Context.RewritePath("~/search.aspx?key=" + firstname);
            }
            if (listparam.Length > 1 && listparam[0] == "/imagesinfo")
            {
                string firstname = listparam[1];
                _application.Context.RewritePath("~/imagesinfo.aspx?id=" + firstname);
            }
            if (listparam.Length > 1 && listparam[0] == "/video")
            {
                string firstname = listparam[1];
                _application.Context.RewritePath("~/video.aspx?id=" + firstname);
            }
            if (listparam.Length > 1 && listparam[0] == "/imagesinfo")
            {
                string firstname = listparam[1];
                _application.Context.RewritePath("~/imagesinfo.aspx?id=" + firstname);
            }
            //这是笑话content
            string[] infoparam = requesturl.Split(new char[] { '-' });
            if (infoparam.Length > 1 && infoparam[0] == "/info")
            {
                string firstname = infoparam[1];
                if (Reg.RegString.IsInt(firstname))
                    _application.Context.RewritePath("~/info.aspx?id=" + firstname);
            }
        }
        #endregion
    }
