Global.asax的Application_BeginRequest實現url重寫無後綴的代碼

利用Global.asax的Application_BeginRequest 實現url 重寫 無後綴
復制代碼 代碼如下:
<%@ Application Language="C#" %>

<script RunAt="server">
void Application_BeginRequest(object sender, EventArgs e)
{
string oldUrl = System.Web.HttpContext.Current.Request.RawUrl; //獲取初始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>
