ASP.NET MVC中针对不同动作的不同路由

本文关键字：路由 NET MVC ASP | 更新日期: 2023-09-27 18:18:45

我正在使用ASP建立一个网站。净MVC。在RouteConfig中，我这样修改了方法:

public static void RegisterRoutes(RouteCollection routes)
{
     routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
     routes.MapRoute(
         name: "Default",
         url: "{Director}/{Movie}/{id}",
         defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional, Director = UrlParameter.Optional, Movie = UrlParameter.Optional }
         );
     routes.MapRoute(
         name: "Default2",
         url: "{controller}/{action}/{id}",
         defaults: new { controller = "Movies", action = "Create", id = UrlParameter.Optional }
         );            
}

在IndexView中，我编写如下代码:

@model IEnumerable<MvcMovie.Models.Director>
<table>
    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.Name)
            </td>
        </tr>
        <tr>
            <td>
                @foreach (var movie in item.Movies)
                {
                    <div style="width: 100%;">
                        @Html.ActionLink(movie.Title, "Index", new { Director = movie.Director.Name, Movie = movie.Title }, null)
                    </div>
                }
            </td>
        </tr>
    }
</table>

实际上我修改了RouteConfig，因为我想为不同的导演和不同的电影提供不同的url，以满足我们客户的SEO requirement。

它是工作良好的Index行动，但即使当我试图调用Create行动使用@Html.ActionLink("Create New", "Create")，它仍然调用Index行动。根据我目前的理解，它应该调用Create Action。我是新的MVC所以抱歉，如果我的问题似乎很愚蠢。但是我在这里漏掉了什么重要的东西呢?

ASP.NET MVC中针对不同动作的不同路由

路由配置是自顶向下检查的。

Update:你应该在路由中指定控制器名，否则就像你的问题中的routecconfig一样，Default2永远不会被触发。有两个路由以{something}开头意味着第二个路由不会被触发。我猜你想要你的URL是localhost/movies/create/id。为此，执行以下操作:

public static void RegisterRoutes(RouteCollection routes)
{
     routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
     routes.MapRoute(
         name: "MoviesDefault",
         url: "Movies/{action}/{id}",
         defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional }
         );  
     /* not sure about this route without testing - 
     /* i think it would conflict with the above route
     routes.MapRoute(
         name: "MovieDirector",
         url: "Movies/{Director}/{Movie}/{id}",
         defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional, Director = UrlParameter.Optional, Movie = UrlParameter.Optional }
         );
     */
     // for this following route, i've left 'Movies' as the controller, but it should be 
     // your 'home page' controller. As in, whatever your default http://localhost:port/ should be.
     routes.MapRoute(
         name: "Default",
         url: "{controller}/{action}/{id}",
         defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional }
     ); 
}

你能不能按这个修改并检查一下?

我相信当url是

//http://localhost/Movies/Create/1 -> invokes Movies controller and Create action.
 public static void RegisterRoutes(RouteCollection routes)
    {
         routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
         routes.MapRoute(
             name: "MoviesCreate",
             url: "Movies/{Movies}/Create/{id}",
             defaults: new { controller = "Movies", action = "Create", id = UrlParameter.Optional }
             );    
//http://Movies/JCameron/Titanic/12 -> invokes Movies controller and Index action.
         routes.MapRoute(
             name: "MoviesHome",
             url: "Movies/{Director}/{Movie}/{id}",
             defaults: new { controller = "Movies", action = "Index", id = UrlParameter.Optional, Director = UrlParameter.Optional, Movie = UrlParameter.Optional }
             );
}

我不是百分之百确定，你需要一些修改。但是你不能传递类似类型的url模式并调用两个控制器。

根据你问题中的代码，如果url匹配，它将始终调用第一个路由。你对第二条路线也使用同样的模式。所以第二条路线总是隐藏的。
