Request.Referer的乱码终极解决方法+获得用户是用什么关键字通过搜索引擎进来的分类：ASP.NET2009-12-1018:08255人阅读评论(0)收藏举报当你想获取Url字符串的时候，最好不要直接调用Request.UrlReferrer.ToString()方法，因为这样有可能返回的是一堆乱码。产生的原因是，用户在来你网站之前的那个网站的编码方式（Encoding)也许和你的网站不一样，导致UrlDecode的时候出现了乱码。这里建议使用Request.UrlReferrer.OriginalString，这个属性返回的就是当时构造Uri对象的原始Url。以下为获得用户是用什么关键字通过搜索引擎进来的方法viewplaincopytoclipboardprint?1.stringRegx="";2.stringRefUrl=Request.UrlReferrer.OriginalString;3.//Response.Write(HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("gb2312")));4.if(RefUrl.ToLower().Contains("google"))5.{6.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("utf-8"));7.Regx="&q=(?[//w*%+]*).*";8.}9.if(RefUrl.Contains("baidu.com"))10.{11.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("gb2312"));12.Regx="wd=(?[//w*%+]*).*";13.}14.if(RefUrl.Contains("soso.com"))15.{16.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("gb2312"));17.Regx="w=(?[//w*%+]*).*";18.}19.if(RefUrl.Contains("sogou.com"))20.{21.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("gb2312"));22.Regx="query=(?[//w*%+]*).*";23.}24.if(RefUrl.Contains("yahoo.com"))25.{26.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("utf-8"));27.Regx="p=(?[//w*%+]*).*";28.}29.if(RefUrl.Contains("bing.com"))30.{31.RefUrl=HttpUtility.UrlDecode(RefUrl,System.Text.Encoding.GetEncoding("utf-8"));32.Regx="q=(?[//w*%+]*).*";33.}34.if(Regx=="")35.{36.ForSearcherDiv.Visible=false;37.return;38.}39.Regexr=newRegex(Regx);//定义一个Regex对象实例40.Matchm=r.Match(RefUrl);//在字符串中匹配41.42.//Response.Write("
