本文介绍的程序主要实现根据IP地址或地址段或IP所在城市进行自动跳转到指定页面的功能,需要的朋友可以参考下

对于大中型网站，为了增强用户体验，往往需要根据不同城市站点的用户推送或展现相应个性化的内容，如对于一些大型门户网站的新闻会有城市站点的功能，如果没有设置相应的城市站点，默认就是根据用户访问的IP地址的所在城市自动设置。本文主要通过自定义扩展IHttpModule接口，考虑到性能IP数据库主要采用QQwry纯真IP数据库，主要实现根据IP地址或地址段或IP所在城市进行自动跳转到指定页面的功能(支持Nginx作为前端反向代理服务器），该WebsiteSkip组件核心代码如下：代码如下:using System;using System.Collections.Generic;using System.Text;using System.Web;using System.Xml;using System.IO;using System.Net;using System.Text.RegularExpressions;using NetOpen_System.Component.QQWry; namespace NetOpen_System.Component{ public sealed class WebsiteSkipHttpModule : IHttpModule { #region IHttpModule 成员 public void Dispose() { } public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(context_BeginRequest); } #endregion void context_BeginRequest(object sender, EventArgs e) { try { //if (HttpContext.Current.Request.IsLocal)//忽略本地计算机请求 // return; //string ip = HttpContext.Current.Request.UserHostAddress; //string ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString(); string ip = string.Empty; if (HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"] != null) { ip = HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"].ToString(); } else if (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null) { ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); } else if (HttpContext.Current.Request.ServerVariables["HTTP_VIA"] != null) { ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); } else { ip = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString(); } QQWryLocator qqWry = new QQWryLocator(HttpContext.Current.Server.MapPath(@"~IpDataqqwry.dat")); IPLocation ipaddress = qqWry.Query(ip); //查询一个IP地址 string ls_city = ipaddress.Country; string ls_urlfrom = string.Empty; string ls_urlto = string.Empty; string ls_url = HttpContext.Current.Request.Url.AbsoluteUri; string ls_useragentkeyword = string.Empty; ExcludeUserAgentMatchEngine Em = WebsiteSkipConfiguration.GetConfig().ExcludeUserAgents; if(Em.ExcludeUserAgentList.Count > 0) { foreach (ExcludeUserAgent ua in Em.ExcludeUserAgentList) { if (HttpContext.Current.Request.UserAgent.Contains(ua.keyword)) { return; } } } UrlMatchEngine pu = WebsiteSkipConfiguration.GetConfig().SkipedUrls; if (pu.UrlList.Count > 0) { foreach (SkipedUrl sk in pu.UrlList) { if (ls_city.Contains(sk.IpCity)) { if (sk.UrlFrom.Length > 0) { if (sk.UrlFrom.Contains(ls_url) && !ls_url.Contains(sk.OutKey
