.NET MVC3.0 伪静态实现

关于.NET MVC的伪静态实现，网上有很多博文介绍，但都不能实现真正的伪静态，或者适应更复杂的伪静态需求，比如分页查询的页面。

首先，我们要写一个路由拦截器，其中的一些拦截规则处理，需要你根据实际情况处理，我这里只是扩展了分页查询的伪静态处理，代码如下：

    public class MVCHtmlRoute : RouteBase
    {
        public MVCHtmlRoute()
        {

        }

        public override RouteData GetRouteData(HttpContextBase httpContext)
        {
            RouteData result = null;
            string requestedURL =
                httpContext.Request.AppRelativeCurrentExecutionFilePath + httpContext.Request.PathInfo;
            List<string> URLItemList = requestedURL.Split('/').ToList();
            if(URLItemList.Count()==3)
            {//缺Action
                int extpos = URLItemList[2].IndexOf(".html");
                int pagepos = URLItemList[2].IndexOf("_");
                if (extpos > 0)
                {
                    result = new RouteData(this, new MvcRouteHandler());
                    result.Values.Add("controller", URLItemList[1]);
                    result.Values.Add("action", "Index");
                    if (pagepos > 0)
                    {//分页参数分割
                        result.Values.Add("id", URLItemList[2].Substring(0, pagepos));
                        result.Values.Add("page", URLItemList[2].Substring(pagepos + 1, extpos - pagepos-1));
                    }
                    else
                    {
                        result.Values.Add("id", URLItemList[2].Substring(0, extpos)); 
                    }
                }
            }
            return result;
        }

        public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
        {
            return null;
        }

    }

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.Add(new Lib.MVCHtmlRoute());

            routes.MapRoute(
                "ID_PAGEHtml", // id伪静态 扩展分页参数page
                "{controller}/{action}/{id}_{page}.html",// 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional, page = UrlParameter.Optional }// 参数默认值
            );

            routes.MapRoute(
                "IDHtml", // id伪静态
                "{controller}/{action}/{id}.html",// 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional }// 参数默认值
            );

            routes.MapRoute(
                "ActionHtml", // action伪静态
                "{controller}/{action}.html/{id}",// 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional }// 参数默认值
            );

            routes.MapRoute(
                "ControllerHtml", // controller伪静态
                "{controller}.html/{action}/{id}",// 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional }// 参数默认值
            );
            //以下保证未做伪静态处理的链接也能正常识别
            routes.MapRoute(
               "Default",
               "{controller}/{action}/{id}",
               new { controller = "Home", action = "Index", id = UrlParameter.Optional }// 参数默认值
            );

            routes.MapRoute(
                "Root", 
                "",
                new { controller = "Home", action = "Index", id = UrlParameter.Optional });//根目录匹配
        }
