asp.net-mvc - 路由中第一个参数的默认值

Question

我有一个路线，可以按流派、标签、风格等显示多语言网站的绘画作品。

看起来不错，类似于

en/Genre/allegorical-painting

但是，客户想要的是排除英语中的 en 并只得到

Genre/allegorical-painting

我默认使用“en”，但它始终呈现......当我手动删除它时，出现 404 错误。这是我的规则定义:

var searchActionsConstraint = new RouteValueDictionary { { "action", "Style|Tag|Painting-School|Art-Movement|Artist-by-Genre|Gallery|Search|Genre|Technique|Material" }, {"lang", "en|es|fr"} };
DomainRoute wikiSearchRoute = new Route("{lang}/{action}/{SearchTerm}/{CurrentPage}/{SearchCategory}/{searchTextMode}",
new RouteValueDictionary(new
{
 lang = "en",
 controller = "WikiSearch",
 action = "",
 SearchTerm = "Any",
 CurrentPage = "1",
 SearchCategory = "Painting",
 searchTextMode = "SearchTags"
}), searchActionsConstraint, new DomainRouteHandler());

RouteTable.Routes.Add("WikiSearchRoute", wikiSearchRoute);

一般来说，如何在 MVC 中第一次隐藏默认路由参数？

Answer 1

您可以添加第二条不带语言的路由，并为其指定默认值

DomainRoute wikiSearchRouteEn = new Route("{action}/{SearchTerm}/{CurrentPage}/{SearchCategory}/{searchTextMode}",
new RouteValueDictionary(new
{
 lang = "en",
 controller = "WikiSearch",
 action = "",
 SearchTerm = "Any",
 CurrentPage = "1",
 SearchCategory = "Painting",
 searchTextMode = "SearchTags"
}), searchActionsConstraint, new DomainRouteHandler());

RouteTable.Routes.Add("WikiSearchRouteEn", wikiSearchRouteEn);
