题

我想创建从MS SQL Server加载的ASP.NET 4.0动态页面。基本上，它是带有信息的位置列表。例如：

Location1 would have the page www.site.com/location/location1.aspx
Location44 would have the page www.site.com/location/location44.aspx

我什至不知道从哪里开始，可能会重写URL？

有帮助吗？

解决方案

URL重写与您所描述的问题不同。

您可以使用将请求处理到路径的httphandler location 并解析最后一个段以获取查找键，然后只需将执行权传递到.aspx即可。尽管您将执行权传递到一般页面，但URL将保持为输入。

我将提供一个例子。试一试。 这是一个示例项目

locationhandler.cs

using System.IO;
using System.Web;

namespace DBHandler
{
    public class LocationHandler : IHttpHandler
    {
        #region IHttpHandler Members

        public void ProcessRequest(HttpContext context)
        {
            HttpRequest request = context.Request;
            string page = Path.GetFileNameWithoutExtension(request.Url.Segments[request.Url.Segments.Length - 1]);

            // for url ~/location/location33.aspx page will be 'location33'

            // do something interesting with page, perhaps 
            context.Server.Execute("~/locations.aspx?locationId=" + context.Server.UrlEncode(page));
        }

        public bool IsReusable
        {
            get { return false; }
        }

        #endregion
    }
}

位置

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Text = Request["locationId"];
    }
</script>

    <div>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </div>
    </form>
</body>
</html>

web.config摘录

...
<system.web>
  ...
  <httpHandlers>
    <add verb="*" path="location/*.*" type="DBHandler.LocationHandler"/>
  </httpHandlers>
</system.web>
