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;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;
using System.Globalization;
namespace MvcApplication1.UserRoutes
{
public class MonthRouteContraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
if ((routeDirection == RouteDirection.IncomingRequest) && (parameterName.ToLower(CultureInfo.InvariantCulture) == "month"))
{
try
{
int month = Convert.ToInt32(values["month"]);
if ((month >= 1) && (month <= 12))
{
return true;
}
return false;
}
catch (Exception ex)
{
return false;
}
}
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.
