asp.net mvc和路由

Question

我在Controller中有以下操作

public ActionResult Index(int? pageNumber)
public ActionResult Details(string seoFriendlyName)

我想要有以下几条路线：

~/article/ -> Action = Index, pageNumber = 1
~/article/page-5 -> Action = Index, pageNumber = 5
~/article/page-1 -> ~/article/
~/article/foo -> Action = Details, seoFriendlyName = foo

我尝试定义以下路由，但它不起作用：

routes.MapRoute(
                null,
                "article/page-{pageNumber}",
                new { controller = "MyController", action = "Index", pageNumber = 1 },
                new[] { "MyNamespace" }
);

routes.MapRoute(
                null,
                "article",
                new { controller = "MyController", action = "Index", },
                new[] { "MyNamespace" }
);

routes.MapRoute(
                null,
                "article/{seoFriendlyName}",
                new { controller = "MyController", action = "Details", },
                new[] { "MyNamespace" }
);

任何帮助都将不胜感激！

Answer 1

你的要求是自相矛盾的。例如，如果您有一篇包含seoFriendlyName == "page-6“和实际pageNumber == 2的文章，应该选择哪条路由？

我建议您将您的需求更改为

~/article/ -> Action = Index, pageNumber = 1
~/article/page/5 -> Action = Index, pageNumber = 5
~/article/page/1 -> ~/article/
~/article/foo -> Action = Details, seoFriendlyName = foo

然后，您将拥有以下路由：

routes.MapRoute(
                null,
                "article/page/{pageNumber}",
                new { controller = "MyController", action = "Index", pageNumber = 1 },
                new[] { "MyNamespace" }
);

routes.MapRoute(
                null,
                "article",
                new { controller = "MyController", action = "Index", },
                new[] { "MyNamespace" }
);

routes.MapRoute(
                null,
                "article/{seoFriendlyName}",
                new { controller = "MyController", action = "Details", },
                new[] { "MyNamespace" }
);

回应评论：

对于这个特定的需求，你需要这样修改你的路由：

routes.MapRoute(
                null,
                "article",
                new { controller = "MyController", action = "Index", pageNumber = 1 },
                new[] { "MyNamespace" }
);

routes.MapRoute(
                null,
                "article/page/{pageNumber}",
                new { controller = "MyController", action = "Index", },
                new[] { "MyNamespace" }
);


routes.MapRoute(
                null,
                "article/{seoFriendlyName}",
                new { controller = "MyController", action = "Details", },
                new[] { "MyNamespace" }
);

你还没告诉我们，到底是什么出了问题。我看到的唯一一件事是，您为pageNumber参数设置了错误的值。

这应该能更好地工作：

routes.MapRoute(
    null,
    "article",
    new { controller = "MyController", action = "Index", pageNumber = 1 },
    new[] { "MyNamespace" }
);

routes.MapRoute(
    null,
    "article/page-{pageNumber}",
    new { controller = "MyController", action = "Index"},
    new[] { "MyNamespace" }
);

routes.MapRoute(
    null,
    "article/{seoFriendlyName}",
    new { controller = "MyController", action = "Details" },
    new[] { "MyNamespace" }
);
