ASP.NET MVC 路由规则及简述

//以下所有的自定义路由规则必须在默认路由规则之前，否则不起效果 

//直接方法重载+匿名对象

//最基础的路由规则，也是默认的路由规则             routes.MapRoute(                 name: "Default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }             );

//构造路由然后添加             Route myroute = new Route("{controller}/{action}", new MvcRouteHandler());             routes.Add("MyRoute0", myroute);

//添加命名空间的路由

//在Action里面定义了一个参数"catchall"用来接收Url中除了Id之外其他所有的参数值

//catchall 这个就可以实现了多个参数的传递

            //跨命名空间路由             routes.MapRoute(                 "AddContollerRoute",                 "Home/{action}/{id}/{*catchall}",                 new { controller = "Home", action = "Index", id = UrlParameter.Optional },                 new[] { "URLsAndRoutes.AdditionalControllers" }             );             routes.MapRoute(                 "MyRoute1",                 "{controller}/{action}/{id}/{*catchall}",                 new { controller = "Home", action = "Index", id = UrlParameter.Optional },                 new[] { "URLsAndRoutes.Controllers" }             );

//关于{id}后面增加{*catchall}这个配置之后，在action的参数ID之后需要增加 string catchall这个参数来获取除ID之外的所有参数，案例如下：

public ActionResult abcTest(string id,string catchall)         {             string temp = id;             string tt = catchall;

            return Content(id);         }             

//可变长度路由 + 正则表达式匹配路由

//正则表达式 ，在路由配置中，我们做了这样的规则，只匹配Controller名称以H开头的             routes.MapRoute(                 "MyRoute2",                 "{controller}/{action}/{id}/{*catchall}",                 new { controller = "Home", action = "Index", id = UrlParameter.Optional },                 new { controller = "^H.*", action = "^Index$|^About$" },                 new[] { "URLsAndRoutes.Controllers" }             );

            //指定请求方法             routes.MapRoute("MyRoute3", "{controller}/{action}/{id}/{*catchall}",                 new { controller = "Home", action = "Index", id = UrlParameter.Optional },                 new { controller = "^H.*", action = "Index|About", httpMethod = new HttpMethodConstraint("GET") },                 new[] { "URLsAndRoutes.Controllers" }             );
