Global.asax的Application_BeginRequest实现url重写无后缀的代码

<%@ Application Language="C#" %>

<script RunAt="server">

void Application_BeginRequest(object sender, EventArgs e)

{

string oldUrl = System.Web.HttpContext.Current.Request.RawUrl; //获取初始url

//~/123.aspx → ~/Index.aspx?id=123

Regex reg = new Regex(@"^\/\d+\.html");

if (reg.IsMatch(oldUrl))

{

string id = reg.Match(oldUrl).ToString().Substring(1, reg.Match(oldUrl).ToString().LastIndexOf(".") - 1);

Context.RewritePath("~/Index.aspx?id=" + id);

}

//~/123 → ~/Index.aspx?id=123

Regex reg1 = new Regex(@"^\/\d+$");

if (reg1.IsMatch(oldUrl))

{

string id = reg1.Match(oldUrl).ToString().Substring(1);

Context.RewritePath("~/Index.aspx?id=" + id);

}

//~/index/123 → ~/Index.aspx?id=123

Regex reg3 = new Regex(@"^\/index\/\d+$");

if (reg3.IsMatch(oldUrl))

{

string id = reg3.Match(oldUrl).ToString().Substring(7);

Context.RewritePath("~/Index.aspx?id=" + id);

}

}

</script>
