Asp.net MVC 学习笔记 (2) --路由

    这一篇主要介绍Asp.net MVC 路由。

   如下为一些配置实例，以豆瓣为例，可以通过辅助工具RouteDebug调试：

 

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

            //我的豆瓣 http://www.douban.com/people/3675683/notes
            routes.MapRoute("mine", "mine/",
                 new { controller = "mine", action = "index" }
                 );

            //日志首页   http://www.douban.com/people/123123/notes
            routes.MapRoute("noteIndex", "people/{id}/notes",
                 new { controller = "notes", action = "Index" },
                 new { id = @"^[0-9]*[1-9][0-9]*$", httpMethod = new HttpMethodConstraint("GET") }
                 );
            //匹配的参数为负整数
            //routes.MapRoute("noteIndex1", "people/{id}/notes",
            //    new { controller = "notes", action = "Index" },
            //    new { id = @"^((-\d+)|(0+))$" }
            //    );

            //日志详细  http://www.douban.com/note/66652523/
            routes.MapRoute("noteShow", "note/{id}",
                 new { controller = "notes", action = "Show" },
                 new { id = @"^\d+", httpMethod = new HttpMethodConstraint("GET", "POST") }
                 );
            //写日志  http://www.douban.com/note/create
            routes.MapRoute("noteWrite", "note/create",
                  new { controller = "notes", action = "create" }
                  );
            //编辑日志  http://www.douban.com/note/edit/66652523
            routes.MapRoute("noteEdit", "note/update/{id}",
                 new { controller = "notes", action = "edit" },
                 new { id = @"^\d+" }
                 );

            //相册   http://www.douban.com/people/3675683/photos   
            routes.MapRoute("albumIndex", "people/{id}/{controller}",
                 new { controller = "mine", action = "index" },
                 new { id = @"^[0-9]*[1-9][0-9]*$", controller = @"(photos|miniblogs|board)" }//controller 为其中的一种
                 );
            routes.MapRoute("albumEdit", "album/update/{id}.html",
                 new { controller = "album", action = "update" },
                 new { id = @"^\d+" }
                 );

            routes.MapRoute("albumEdit1", "album/update/{id}_{classid}.html",
                 new { controller = "album", action = "update" },
                 new { id = @"^\d+", classid = @"^\d+" }
                 );


            // Archive/2008-05-07/123.html 这个还没用判断 月和日的关系
            routes.MapRoute(
                "archive",
                "archive/{date}/{id}.html",
                new { controller = "archive", action = "show" },
                new { date = @"^\d{4}-\d{2}-\d{2}", id = @"^\d+" });
            //复杂点的  http://www.cnblogs.com/news/2010/10/09/1846556.html
            routes.MapRoute(
                "news",
                "news/{year}/{month}/{day}/{id}.html",
                new { controller = "news", action = "show", year = "", month = "", day = "" },
                new
                {
                    id = @"^\d+",
                    year = new YearRouteContraint(),
                    month = new MonthRouteContraint(),
                    day = new DayRouteContraint()
                });

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
            );

            

        }

        protected void Application_Start()
        {

            RegisterRoutes(RouteTable.Routes);
            RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);
            RouteTable.Routes.RouteExistingFiles = true;


            //  AreaRegistration.RegisterAllAreas();

            //   RegisterRoutes(RouteTable.Routes);
        }

 

   其中自定义路由的类如下，这个到处都有：

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;
using System.Globalization;
 
namespace MvcApplication1.UserRoutes
{
    public class YearRouteContraint : IRouteConstraint
    {
        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
        {
            if ((routeDirection == RouteDirection.IncomingRequest) && (parameterName.ToLower(CultureInfo.InvariantCulture) == "year"))
            {
                try
                {
                    int year = Convert.ToInt32(values["year"]);
                    if ((year >= 1900) && (year <= 2100))
                    {
                        return true;
                    }
                    return false;
                }
                catch (Exception ex)
                {
                    return false;
                }
              
            }
            return false;
        }
    }
}

using System;

                    if ((month >= 1) && (month <= 12))
                    {
                        return true;
                    }
                    return false;
                }
                catch (Exception ex)

            }
            return false;
        }
    }

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;
using System.Globalization;
 
 

namespace MvcApplication1.UserRoutes
{
    public class DayRouteContraint:IRouteConstraint
    {

        #region IRouteConstraint 成员

        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
        {
            if ((routeDirection == RouteDirection.IncomingRequest) && (parameterName.ToLower(CultureInfo.InvariantCulture) == "day"))
            {
                try
                {
                  

                    int month = int.Parse(values["Month"].ToString());
                     
                    int day = int.Parse(values["Day"].ToString());
 

                    if (month <= 0 || month > 12) return false;
                    if (day < 1) return false;
                    switch (month)
                    {
                        case 1:
                        case 3:
                        case 5:
                        case 7:
                        case 8:
                        case 10:
                        case 12:
                            if (day < 32) return true;
                            break;
                        case 2:
                            if (day < 29) return true;
                            break;
                        case 4:
                        case 6:
                        case 9:
                        case 11:
                            if (day < 31) return true;
                            break;
                    }
                }
                catch
                {
                    return false;
                }
            }
            return false;
        }

        #endregion
    }
}

当然您还可以在Asp.net WebForm中使用路由，这就不介绍了.
