[英]How to map a route for /News/5 to my news controller
I am trying to identify how to map a route for /News/5 to my news controller. 我正在尝试确定如何将/ News / 5的路由映射到我的新闻控制器。
This is my NewsController: 这是我的NewsController:
public class NewsController : BaseController
{
//
// GET: /News
public ActionResult Index(int id)
{
return View();
}
}
This is my Global.asax.cs rule: 这是我的Global.asax.cs规则:
routes.MapRoute(
"News", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "News", action = "Index", id = -1 } // Parameter defaults
);
I try to go to /News/5 but I receive a resource not found error, however when going to /News/Index/5 it works? 我尝试去/ News / 5但是我收到了资源未找到错误,但是当进入/ News / Index / 5时它有效吗?
I have tried just {controller}/{id}
but that just produced the same issue. 我只试过
{controller}/{id}
但这只是产生了同样的问题。
Thanks! 谢谢!
Your {controller}/{id}
route was correct but you problaby registered it AFTER the other route. 您的
{controller}/{id}
路由是正确的,但是您在另一条路线之后注册了它。 In the route list it searches top down and the first match it finds wins. 在路线列表中,它自上而下搜索并找到匹配的第一个匹配。
To help steer routing I would suggest creating route constraints for this to ensure that #1 the controller exists and #2 the {id}
is a number. 为了帮助引导路由,我建议为此创建路由约束,以确保#1控制器存在,#2
{id}
是一个数字。

Mainly: 主要是:
routes.MapRoute(
"Index Action", // Route name
"{controller}/{id}", // URL with parameters EDIT: forgot starting "
new { controller = "News", action = "Index" },
new {id= @"\d+" }
);
You need to make sure your new route is before your default route, like so: 您需要确保新路由在默认路由之前,如下所示:
routes.MapRoute(
"NewsAbbr", // Route name
"{controller}/{id}", // URL with parameters
new { controller = "News", action = "Index", id = -1 } // Parameter defaults
);
routes.MapRoute(
"News", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "News", action = "Index", id = -1 } // Parameter defaults
);
