asp.NET:未知长度的MVC路径

Question

我正在asp.NET中为Web门户构建MVC应用程序.我准备了一系列控制器,并将所有不与之对应的路径映射到Page控制器,这将呈现适当的页面.

我的默认路由如下:

routes.MapRoute(
  "Default",
  "{level1}/{level2}/{level3}",
  new { controller = "Page", action = "Index", level1 = "home", level2 = "", level3 = "" }
      );

但这有固定的宽度,它只接受最多3个级别.此外,我想管理附加到路径的操作,例如"编辑"和"删除".这可能吗？

company/about/who_we_are/staff -> Controller: Page, Action: Index, Parms: company/about/who_we_are/staff
company/about/who_we_are/staff/edit  -> Controller: Page, Action: Edit, Parms: company/about/who_we_are/staff
company/edit  -> Controller: Page, Action: Edit, Parms: company

或者有更好的方法对此进行建模吗？页面的所有路径都在数据库中,因此它们会动态更改.

您可以使用通配符路由:

"{*data}"

看看这个SO:ASP.net MVC自定义路由处理程序/约束

简单的解决方案:

(未经测试但......)

路线:

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