c# – MVC Routing .net Core

在我早期的.net应用程序中,我曾经在route.config中使用以下路由

routes.MapRoute(
name: "Default",
url: "{tenant}/{controller}/{action}/{id}",
defaults: new { tenant = "GRE", controller = "Home", action = "Index", id = UrlParameter.Optional }
);

现在我转移到.Net Core,不知怎的,我无法在startup.cs中设置类似的路由

我尝试过如下,但它从未打过.

 app.UseMvc(routes =>
            {  
                routes.MapRoute("testroute", "{tenant}/{controller}/{action}/{id}",
                        defaults: new { tenant = "GRE", controller = "Home", action = "Index" });

            });

HomeController.cs

public IActionResult Index(string tenant)
        {
            return View();
        }

欣赏任何有关如何使其工作的帮助或提示

谢谢,

解决方法:

你的id参数,你的asp.net mvc代码是可选的,在asp.net核心代码中不是可选的,没有默认值,因此它不匹配.要使其可选,请添加“？”到名称,或设置默认值：

app.UseMvc(routes =>
{
    routes.MapRoute("testroute", "{tenant}/{controller}/{action}/{id?}",
        defaults: new { tenant = "GRE", controller = "Home", action = "Index" });

});

您还可以设置内联默认值,如下所示：

routes.MapRoute("testroute", "{tenant=GRE}/{controller=Home}/{action=Index}/{id?}");
