一、路由规则
1、可以创建多条路由规则，每条路由的name属性不相同
2、路由规则有优先级，最上面的路由规则优先级越高
App_Start文件下的：RouteConfig.cs
1 public static void RegisterRoutes(RouteCollection routes) 2 { 3 routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 4 5 routes.MapRoute( 6 name: "Default2", 7 url: "{controller}-{action}", 8 defaults: new { controller = "HomeDemo", action = "Index" } 9 ); 10 11 routes.MapRoute( 12 name: "Default", 13 url: "{controller}/{action}/{id}", 14 defaults: new { controller = "HomeDemo", action = "Index", id = UrlParameter.Optional } 15 ); 16 } 17 }
二、路由调试工具
当为我们的应用程序注册多个路由后，由于注册不当，得不到预期的结果。为什么会发生这种情况，请求具体走了哪个路由？这个时候主人公RegisterRoutes上场了。
第一步：先下载dll类库，没有的请到我百度云盘下载

第二步：引入包：RouteDebug
第三步：到Global.asax中重写测试路径
1 public class MvcApplication : System.Web.HttpApplication 2 { 3 protected void Application_Start() 4 { 5 AreaRegistration.RegisterAllAreas(); 6 FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 7 RouteConfig.RegisterRoutes(RouteTable.Routes); 8 BundleConfig.RegisterBundles(BundleTable.Bundles); 9 10 RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); //重写测试路径 11 } 12 }
第四步：运行网站，进行分析路由规则
搞定！~~
三、路由的约束
1 public class RouteConfig 2 { 3 public static void RegisterRoutes(RouteCollection routes) 4 { 5 routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 6 7 routes.MapRoute( 8 name: "Default2", 9 url: "{controller}-{action}", 10 defaults: new { controller = "HomeDemo", action = "Index" }, 11 constraints:new {Controller=@"^d+$" }, //控制器约束 12 namespaces:new string[] { "MVCDemo2.Controllers" } //命名空间约束 13 ); 14 15 routes.MapRoute( 16 name: "Default", 17 url: "{controller}/{action}/{id}", 18 defaults: new { controller = "HomeDemo", action = "Index", id = UrlParameter.Optional } 19 ); 20 } 21 }
