从ASP.net MVC路由获取url路径

标签: c# asp.net-mvc routing routes

我有一个看起来像这样的控制器:

public class PageController : Controller
{
    public ActionResult Render(string url)
    {
        //this is just for testing!
        return Content("url was " + url);
    }
}

我正在尝试将url的值传入控制器。例如:
http://www.site.com/products/something/else

将“products / something / else”传递给PageController的Render操作。

这是因为我们使用“products / something / else”作为数据库中记录的唯一键(遗留系统,不要问)

所以,我的结果查询将是这样的:

select * from foo where urlKey = 'products/something/else'

到目前为止,我在Global.asax的RegisterRoutes部分中有这个:

routes.MapRoute("pages", "{*url}", new { controller = "Page", action = "Render", url="/" });

但这不符合预期......

访问www.site.com/products/something/else,传入控制器的值为“home / index / 0”
RegisterRoutes中定义的唯一路径是问题中描述的路径。

以下课程与每条路线相匹配,但您可以根据自己的需要进行修改。

public class LegacyRoute : RouteBase
{
    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
      RouteData result = null;

      string url = httpContext.Request.RawUrl.Substring(1);

      result = new RouteData(this, new MvcRouteHandler());
      result.Values.Add("controller", "Page");
      result.Values.Add("action", "Render");
      result.Values.Add("url", url);

      return result;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
      return null;
    }
}

在Global.asax.cs

routes.Add(new LegacyRoute());

希望这会有所帮助,我们的其中一条路线做了类似的事情,这就是代码:

   routes.MapRoute(
            name: "Standard",
            url: "{controller}/{action}/{id}",
            defaults: new { id = UrlParameter.Optional, action = ControllersAndActions.TypicalController.IndexAction, page = 1 },
            constraints: new
            {
                controller = ControllersAndActions.ControllerConstraintExpression
            }
        );
