使用彈頭

Question

我試圖創建一個通用的路線蛞蝓的工作，但我C＃泛型的mvc路線總是得到一個錯誤

的想法是，而不是www.site.com/controller/action我在網址友好www.site.com/{slug}

eg www.site.com/Home/Open將代替www.site.com/open-your-company

錯誤

服務器 '/' 應用程序錯誤的資源不能發現

在我的Global.asax我

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

    routes.MapRoute("DefaultSlug", "{slug}", new { controller = "Home", action = "Open", slug = "" }); 
    routes.MapRoute(
     name: "Default", 
     url: "{controller}/{action}/{id}", 
     defaults: new 
     { 
      area = "", 
      controller = "Home", 
      action = "Index", 
      id = UrlParameter.Optional, 
      slug = "" 
     } 
    ); 
} 

在我的一個cshtml我有以下鏈接（即使它被評論，仍然有相同的錯誤）。

@Html.ActionLink("Open your company", "DefaultSlug", new { controller = "Home", action = "Open", slug = "open-your-company" }) 

編輯：HomeController的

public ActionResult Open() { 
    return View(new HomeModel()); 
}

在Global.asax中你slug如果爲空，將URL不會去默認路由

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

    routes.MapRoute(
     name: "DefaultSlug", 
     url: "{slug}", 
     defaults: new { controller = "Home", action = "Open" }, 
     constraints: new{ slug=".+"}); 

    routes.MapRoute(
     name: "Default", 
     url: "{controller}/{action}/{id}", 
     defaults: new 
     { 
      area = "", 
      controller = "Home", 
      action = "Index", 
      id = UrlParameter.Optional 
     } 
    ); 
} 

和更新不能爲空， HomeController

public ActionResult Open(string slug) { 
    HomeModel model = contentRepository.GetBySlug(slug); 

    return View(model); 
} 

測試路線鏈接...

@Html.RouteLink("Open your company", routeName: "DefaultSlug", routeValues: new { controller = "Home", action = "Open", slug = "open-your-company" }) 

和動作鏈接...

@Html.ActionLink("Open your company", "Open", routeValues: new { controller = "Home", action = "Open", slug = "open-your-company" }) 

都產生......

http://localhost:35979/open-your-company

這是我走上完成類似任務的步驟。這依靠模型上的自定義Slug字段來匹配路線。

1. 設置您的控制器例如控制器\ PagesController.cs：

   public class PagesController : Controller 
   { 
       // Regular ID-based routing 
       [Route("pages/{id}")] 
       public ActionResult Detail(int? id) 
       { 
        if(id == null) 
        { 
         return new HttpNotFoundResult(); 
        } 
   
        var model = myContext.Pages.Single(x => x.Id == id); 
        if(model == null) 
        { 
         return new HttpNotFoundResult(); 
        } 
        ViewBag.Title = model.Title; 
        return View(model); 
       } 
   
       // Slug-based routing - reuse View from above controller. 
       public ActionResult DetailSlug (string slug) 
       { 
        var model = MyDbContext.Pages.SingleOrDefault(x => x.Slug == slug); 
        if(model == null) 
        { 
         return new HttpNotFoundResult(); 
        } 
        ViewBag.Title = model.Title; 
        return View("Detail", model); 
       } 
   } 
   

2. 成立App_Start \ RouteConfig.cs

   路由

   public class RouteConfig 
   { 
       public static void RegisterRoutes(RouteCollection routes) 
       { 
        // Existing route register code 
   
        // Custom route - top priority 
        routes.MapRoute(
          name: "PageSlug", 
          url: "{slug}", 
          defaults: new { controller = "Pages", action = "DetailSlug" }, 
          constraints: new { 
           slug = ".+", // Passthru for no slug (goes to home page) 
           slugMatch = new PageSlugMatch() // Custom constraint 
          } 
         ); 
        } 
   
        // Default MVC route setup & other custom routes 
       } 
   } 
   

3. 定製IRouteConstraint例如實施utils的\ RouteConstraints.cs

   public class PageSlugMatch : IRouteConstraint 
   { 
       private readonly MyDbContext MyDbContext = new MyDbContext(); 
   
       public bool Match(
        HttpContextBase httpContext, 
        Route route, 
        string parameterName, 
        RouteValueDictionary values, 
        RouteDirection routeDirection 
       ) 
       { 
        var routeSlug = values.ContainsKey("slug") ? (string)values["slug"] : ""; 
        bool slugMatch = false; 
        if (!string.IsNullOrEmpty(routeSlug)) 
        { 
         slugMatch = MyDbContext.Pages.Where(x => x.Slug == routeSlug).Any(); 
        } 
        return slugMatch; 
       } 
   }
