ASP.NET MVC的URL路由与多路径的值 [英] ASP.NET MVC URL Routing with Multiple Route Values

问题描述

我有Html.ActionLink麻烦，当我有需要多个参数的路线。例如，给定在我Global.asax文件中定义的以下路线：

I am having trouble with Html.ActionLink when I have a route that takes more than one parameter. For example, given the following routes defined in my Global.asax file:

routes.MapRoute(
    "Default",                                              // Route name
    "{controller}.mvc/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
);

routes.MapRoute(
    "Tagging",
    "{controller}.mvc/{action}/{tags}",
    new { controller = "Products", action = "Index", tags = "" }
);

routes.MapRoute(
    "SlugsAfterId",
    "{controller}.mvc/{action}/{id}/{slug}",
    new { controller = "Products", action = "Browse", id = "", slug = "" }
);

第一两条路线的工作没有问题，但是当我尝试使用创建动作链接到第三条道路：

The first two routes work without a problem, but when I try to create an action link to the third route using:

<%= Html.ActionLink(Html.Encode(product.Name), "Details", new { id = product.ProductId, slug = Html.Encode(product.Name) }) %>

我最终像一个网址 [站点根目录] /详细信息/ 1？蛞蝓= URL-塞，而我想的网址更像 [站点根目录] /细节/ 1 / URL-塞

任何人都可以看到我错了？

Can anyone see where I am going wrong?

推荐答案

据使用的是完全满足了第一条路线。尝试把默认一个以上的 SlugsAfterId 路线。

It is using the first route that is fully satisfied. Try putting your SlugsAfterId route above the Default one.

这基本上会：？。？。检查默认有一个动作是有一个ID是使用这一个，另送查询字符串的任何其他参数

It's basically going: "Check Default. Got an action? Yes. Got an id? Yes. Use this one and chuck any other parameters in the querystring."

作为一个方面说明，这样做，会让你的默认路线多余的，因为您提供的塞一个默认值参数。

As a side note, doing that will make your Default route redundant as you provide a default value for the slug parameter.
