有一个简单的MVC路线的麻烦

问题描述

遇到一些麻烦一些路线。我不完全理解MVC路由系统让我承受的。

Having some trouble with some routes. I don't fully understand the MVC routing system so bear with me.

我有两个控制器，产品和家庭（有更多的惊喜！）。

I've got two controllers, Products and Home (with more to come!).

我想有家庭访问控制器内的意见，而无需在url家庭型态。基本上我想转成www.example.com/home/about www.example.com/about，但是我还是想preserve的www.example.com/products。

I want to have the views within the Home controller accessible without having to type Home in the url. Essentially I want to turn www.example.com/home/about into www.example.com/about, however I still want to preserve the www.example.com/products.

下面是我有这么远。

Here's what I have so far.

routes.MapRoute( "Home", "{action}", new { controller = "Home" } );

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "home", action = "index", id = UrlParameter.Optional }
);

现在取决于哪一个是第一次，我可以得到一个或其他工作，但不能同时使用。

Now depending on which one is first I can get either one or the other to work, but not both.

推荐答案

我想你可能会寻找的东西，使code的下面笔者所称根控制器。我已经使用这个自己的一对夫妇的网站，它确实使得漂亮的网址，而不是要求您创建更多的控制器，你想，或者重复的URL结束。

I think what you might be looking for is something that that the author of the code below has termed a Root Controller. I have used this myself on a couple sites, and it really makes for nice URLS, while not requiring you to create more controllers that you'd like to, or end up with duplicate URLs.

这路线是在Global.asax中：

This route is in Global.asax:

        // Root Controller Based on: ASP.NET MVC root url’s with generic routing Posted by William on Sep 19, 2009
        //  http://www.wduffy.co.uk/blog/aspnet-mvc-root-urls-with-generic-routing/
        routes.MapRoute(
            "Root",
            "{action}/{id}",
            new { controller = "Root", action = "Index", id = UrlParameter.Optional },
            new { IsRootAction = new IsRootActionConstraint() }  // Route Constraint
        );

有了这个别处定义：

With this defined elsewhere:

    public class IsRootActionConstraint : IRouteConstraint
    {
        private Dictionary<string, Type> _controllers;

        public IsRootActionConstraint()
        {
            _controllers = Assembly
                                .GetCallingAssembly()
                                .GetTypes()
                                .Where(type => type.IsSubclassOf(typeof(Controller)))
                                .ToDictionary(key => key.Name.Replace("Controller", ""));
        }

        #region IRouteConstraint Members

        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
        {
            string action=values["action"] as string;
            // Check for controller names
            return !_controllers.Keys.Contains(action);
        }

        #endregion
    }

该RootActionContraint alows你还有其他的路线，和$ P $隐藏从任何控制器pvents的RootController行动。

The RootActionContraint alows you to still have other routes, and prevents the RootController actions from hiding any controllers.

您还需要创建一个名为根控制器。这不是一个完整实现。的

You also need to create a controller called Root. This is not a complete implementation. Read the original article here
