asp.net-mvc – asp.NET：未知长度的MVC路径

"{*data}"

看看这个SO：ASP.net MVC custom route handler/constraint

简单的解决方案：

(未经测试但……)

路线：

routes.Add(new Route
                           (
                           "{*data}",new RouteValueDictionary(new {controller = "Page",data = ""}),new PageRouteHandler()
                           )
                );

处理程序看起来像：

public class PageRouteHandler : IRouteHandler
{
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new PageHttpHandler(requestContext);
    }
}

class PageHttpHandler : MvcHandler
{
    public PageHttpHandler(RequestContext requestContext)
        : base(requestContext)
    {
    }

    protected override void ProcessRequest(HttpContextBase httpContext)
    {
        IController controller = new PageController();

        ((Controller)controller).ActionInvoker = new PageActionInvoker();

        controller.Execute(RequestContext);
    }
}

class PageActionInvoker : ControllerActionInvoker
{
    protected override ActionResult InvokeActionMethod(ControllerContext controllerContext,ActionDescriptor actionDescriptor,IDictionary<string,object> parameters)
    {
        string data = controllerContext.RouteData.GetRequiredString("data");
        string[] tokens = data.Split('/');


        int lenght = tokens.Length;

        if (lenght == 0)                   
            return new NotFoundResult();

        if (tokens[tokens.Length - 1] == "edit")
        {
            parameters["action"] = "edit";
            lenght--;
        }

        for (int i = 0; i < length; i++)
            parameters["level" + (i + 1).ToString()] = tokens[i];

        return base.InvokeActionMethod(controllerContext,actionDescriptor,parameters);
    }
}
