MVC 省略可选页面参数

发布于 2024-09-07 06:56:07 字数 583 浏览 6 评论 0原文

我想到了以下 URL：

/restaurants/italian/miami.html
/restaurants/italian/miami-p2.html

使用这些路由

routes.MapRoute(null, "{category}/{branch}/{city}-p{page}.html",
                new { controller = "Branch", action = "Index" });
routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index", page = 1 });

现在，对于我的问题，我希望将 url 的“-p{page}”部分设置为可选，而不仅仅是 {page} 参数。这样我就可以使用单个路由，并使用它来映射带有 Url.RouteUrl(RouteValueDictionary) 的出站 URL（如果字典中的页面参数为 1，则自动删除页面部分）。

I have the following URL in mind:

/restaurants/italian/miami.html
/restaurants/italian/miami-p2.html

Using these routes

routes.MapRoute(null, "{category}/{branch}/{city}-p{page}.html",
                new { controller = "Branch", action = "Index" });
routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index", page = 1 });

Now for my question, i want to make "-p{page}" portion of the url optional, not just the {page} parameter. That way i can use a single route and also use it to map outbound urls with Url.RouteUrl(RouteValueDictionary) (which then auto removes the page portion if the page parameter in the dictionary is 1).

我不确定我是否理解你想要什么，但不知何故我认为使用一些正则表达式约束可能会解决您的问题。也许是这样的：

routes.MapRoute(null, "{category}/{branch}/{citywithp}{page}.html",
            new { controller = "Branch", action = "Index" },
            new {citywithp = @"p-\d+$" } );

I am not sure I understand well what you would like, still somehow I think that using some regular expression constraint might solve your problem. Maybe somehow like this:

routes.MapRoute(null, "{category}/{branch}/{citywithp}{page}.html",
            new { controller = "Branch", action = "Index" },
            new {citywithp = @"p-\d+$" } );

为了实现这一点，我需要 3 个路由：

routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index" },
                new { page = "1" });

routes.MapRoute(null, "{category}/{branch}/{city}-p{page}.html",
                new { controller = "Branch", action = "Index" });

routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index", page = 1 });

这样我可以将所有入站 URL 映射到第二个和第三个路由，将出站 URL 映射到第一个和第二个路由。

In order to achieve this i needed 3 routes:

routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index" },
                new { page = "1" });

routes.MapRoute(null, "{category}/{branch}/{city}-p{page}.html",
                new { controller = "Branch", action = "Index" });

routes.MapRoute(null, "{category}/{branch}/{city}.html",
                new { controller = "Branch", action = "Index", page = 1 });

This way i can map all the urls inbound with the second and third route and outbound with the first and second.
