Question

我的RouteConfig中有这个

：

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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


routes.MapRoute(
    name: "StoreSearch",
    url: "{storeName}",
    defaults: new { controller = "Search", action = "Store" }
);

基本上我有一条第二条路线，所以如果我输入localhost:9000/facebook时没有这样的控制器，其名称为facebook，那么我的第二条路由器应该选择facebook作为{{1} }，然后点击我的storeName控制器的Search操作。但目前我得到404。

有什么主意该如何解决？

Answer 1

如果您有一组特定的商店或验证它们的方法，则可以向路线添加约束。

要添加具有匹配谓词的通用约束

public class ServerRouteConstraint : IRouteConstraint
{
    private readonly Func<Uri, bool> _predicate;

    public ServerRouteConstraint(Func<Uri, bool> predicate)
    {
        this._predicate = predicate;
    }

    public bool Match(HttpContextBase httpContext, Route route, string parameterName,
        RouteValueDictionary values, RouteDirection routeDirection)
    {
        return this._predicate(httpContext.Request.Url);
    }
}

然后在路由中添加一个参数

routes.MapRoute(
   name: "StoreSearch",
   url: "{storeName}",
   defaults: new { controller = "Search", action = "Store" }, constraints: 
//this could be new { controller ="pattern" } 
new {
     serverRoute = new ServerRouteConstraint(url =>
     {
//this will check that the route starts with a specific string in this case Settings
         return url.PathAndQuery.StartsWith("/Settings",
      StringComparison.InvariantCultureIgnoreCase);
     })
   });

此外，应从最具体的到最一般的添加路线。

您应将任何自定义路线放置在Match路线上方。
