带有可选部分的 MVC 路由

Question

我想为我的 MVC 页面创建一条如下所示的路线：

/Articles/
/文章/页/2
/Articles/Page/3

我希望默认页面为 1，但如果页面为 1，则实际上不显示 /Page/ 部分。

我开始于：

routes.MapRoute(
    "Articles",
    "Articles/Page/{page}",
            new { controller = "Articles", action = "Index", page = 1 }
);

问题在于，当我这样做时：

 <%= Html.RouteLink("Articles", new { page = 1 }) %>

我的路线最终是： /Articles/Page/

Answer 1

您可能需要两个路由定义（未经测试）：

routes.MapRoute(
    "ArticlesDefault",
    "Articles",
    new { controller = "Articles", action = "Index", page = 1 }
);

routes.MapRoute(
    "Articles",
    "Articles/Page/{page}",
    new { controller = "Articles", action = "Index" }
);

以及您的控制器操作：

public ActionResult Index(int page)
{
    ...
}

Answer 2

将两者都放入：

// This will match routes where the page equals one. Since the page can't
// be specifed here, it will drop to the next one for page values other
// than 1.
routes.MapRoute("Articles",
                "Articles",
                new { controller = "Articles", action = "Index", page = 1 } 
); 

// This route handles pages other than 1
routes.MapRoute(null,
                "Articles/Page/{page}",
                new { controller = "Articles", action = "Index" }
); 

您不需要对控制器执行任何操作。
