這篇文章主要講解了“asp.net實現(xiàn)網(wǎng)站首頁根據(jù)IP自動跳轉指定頁面”,文中的講解內容簡單清晰,易于學習與理解,下面請大家跟著小編的思路慢慢深入,一起來研究和學習“asp.net實現(xiàn)網(wǎng)站首頁根據(jù)IP自動跳轉指定頁面”吧!
創(chuàng)新互聯(lián)公司主營淮安區(qū)網(wǎng)站建設的網(wǎng)絡公司,主營網(wǎng)站建設方案,成都app軟件開發(fā),淮安區(qū)h5重慶小程序開發(fā)公司搭建,淮安區(qū)網(wǎng)站營銷推廣歡迎淮安區(qū)等地區(qū)企業(yè)咨詢對于大中型網(wǎng)站,為了增強用戶體驗,往往需要根據(jù)不同城市站點的用戶推送或展現(xiàn)相應個性化的內容,如對于一些大型門戶網(wǎng)站的新聞會有城市站點的功能,如果沒有設置相應的城市站點,默認就是根據(jù)用戶訪問的IP地址的所在城市自動設置。本文主要通過自定義擴展IHttpModule接口,考慮到性能IP數(shù)據(jù)庫主要采用QQwry純真IP數(shù)據(jù)庫,主要實現(xiàn)根據(jù)IP地址或地址段或IP所在城市進行自動跳轉到指定頁面的功能(支持Nginx作為前端反向代理服務器),該WebsiteSkip組件核心代碼如下:

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)

ls_urlto = WebsiteSkipConfiguration.GetConfig().IpChecks.UrlTo.Trim();

在部署方面,非常簡單主要利用IHttpModule接口并在Web.config中的HttpModule節(jié)點添加此組件的配置,訪問限制或允許參數(shù)可以在NetOpen_SystemWebsiteSkip.cfg.xml進行設置,以下為一個簡單的配置示例:
