Question

这是我的routeconfig.cs

 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
        routes.IgnoreRoute("Background/AutoComplete.aspx/{*webmethod}");
        routes.IgnoreRoute("Background/Misc.aspx");

        routes.MapRoute(
          name: "NoAuthorName",
          url: "Author",
          defaults: new { controller = "Author", action = "Index" });

        routes.MapRoute(
           name: "AuthorNameonly",
           url: "{controller}/{author}",
           defaults: new { controller = "Author", action = "AllQuotesByAuthorWithoutAuthorID" });

        routes.MapRoute(
            name: "AuthorNamewithAuthorID",
            url: "{controller}/{author}/{id}",
            defaults: new { controller = "Author", action = "AllQuotesByAuthorWithAuthorID"});

        routes.MapRoute(
          name: "AllQuotesByAuthorWithAuthorIDandQuoteID",
          url: "{controller}/{author}/{id}/{id1}",
          defaults: new { controller = "Author", action = "AllQuotesByAuthorWithAuthorIDandQuoteID" });

        routes.MapRoute(
        name: "FinalURLwithAuthor",
        url: "{controller}/{author}/{id}/{id1}/{quotesseparatedbyhyphen}",
        defaults: new { controller = "Author", action = "Finalurl" });


        routes.MapRoute(
         name: "NoKeywordName",
         url: "Keyword",
         defaults: new { controller = "Keyword", action = "Index" });

        routes.MapRoute(
          name: "AllQuotesByKeywordwithoutKeywordID",
          url: "{controller}/{key}",
          defaults: new { controller = "Keyword", action = "AllQuotesByKeywordwithoutKeywordID" });

        routes.MapRoute(
           name: "AllQuotesByKeywordWithKeywordID",
           url: "{controller}/{key}/{id}",
           defaults: new { controller = "Keyword", action = "AllQuotesByKeywordWithKeywordID" });


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

这是它的工作原理。 http://sitename.com/Author/Benjamin-Quotes/AuthorID - 有效。

http://sitename.com/Author/Benjamin-Quotes/ - 有效。

http://sitename.com/Author - 有效。

但

http://sitename.com/Keyword - 作品

http://sitename.com/Keyword/Love - 不起作用 404. error

http://sitename.com/Keyword/Love/Keywordid - 不起作用。 404. error

然而，当我删除作者的所有地图路线时，只有在routeconfig.cs

中只有这样的关键字

  routes.MapRoute(
         name: "NoKeywordName",
         url: "Keyword",
         defaults: new { controller = "Keyword", action = "Index" });

        routes.MapRoute(
          name: "AllQuotesByKeywordwithoutKeywordID",
          url: "{controller}/{key}",
          defaults: new { controller = "Keyword", action = "AllQuotesByKeywordwithoutKeywordID" });

        routes.MapRoute(
           name: "AllQuotesByKeywordWithKeywordID",
           url: "{controller}/{key}/{id}",
           defaults: new { controller = "Keyword", action = "AllQuotesByKeywordWithKeywordID" });


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

现在http://sitename.com/Keyword - 作品

http://sitename.com/Keyword/Love - 作品

http://sitename.com/Keyword/Love/Keywordid - 有效。

现在，如果我在routeconfig.cs中混合作者路由和关键字路由以下网址不存在.HTTP 404. error

http://sitename.com/Keyword/Love -

http://sitename.com/Keyword/Love/Keywordid - 。

Answer 1

AllQuotesByKeywordwithoutKeywordID和AllQuotesByKeywordWithKeywordID的路由模式分别与AuthorNameonly和AuthorNamewithAuthorID的路由模式相同。您以不同方式命名路由参数的事实不足以区分路由。因此，第一个匹配wins，在这种情况下是AuthorNameonly和AuthorNamewithAuthorID。换句话说，当您点击/Keyword/Love之类的路线时，Keyword会进入controller，为您提供正确的控制器，但是，Love是放入author param，您对KeywordController的操作将无法使用，因为它正在寻找key参数。此外，由于您未指定操作，因此正在使用默认操作，此路由为AllQuotesByAuthorWithoutAuthorID，这甚至不是KeywordController上的操作，因此您的404。

长短，你需要别的东西来区分这些路线。您可以将路线更改为：

routes.MapRoute(
    name: "AuthorNameonly",
    url: "author/{author}",
    defaults: new { controller = "Author", action = "AllQuotesByAuthorWithoutAuthorID" });

routes.MapRoute(
    name: "AuthorNamewithAuthorID",
    url: "author/{author}/{id}",
    defaults: new { controller = "Author", action = "AllQuotesByAuthorWithAuthorID"});

和

routes.MapRoute(
    name: "AllQuotesByKeywordwithoutKeywordID",
    url: "keyword/{key}",
    defaults: new { controller = "Keyword", action = "AllQuotesByKeywordwithoutKeywordID" });

routes.MapRoute(
    name: "AllQuotesByKeywordWithKeywordID",
    url: "keyword/{key}/{id}",
    defaults: new { controller = "Keyword", action = "AllQuotesByKeywordWithKeywordID" });

换句话说，不是让controller参数变量，而是明确指定它。现在，只有URL路径的第一部分匹配时，每条路径才会匹配，从而消除歧义。

routeconfig.cs - 页面不存在
