asp.net mvc 和路由答案

【问题描述】：

我在控制器中有以下操作

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

我想有以下路线：

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

我尝试定义以下路线，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" }
);

任何帮助将不胜感激！

【解决方案1】：

您的要求是自相矛盾的。例如，如果您有一篇文章 seoFriendlyName == "page-6" 和实际 pageNumber == 2，应该选择什么路由？

我建议您将要求更改为

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

然后你将有以下路线：

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" }
);

更新

回应cmets：

对于该特定要求，您需要以这种方式修改您的路线：

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" }
);

【讨论】：

如果我调用Url.Action("Index", "MyController")，那么~/article/page 将被渲染而不是~/article
如果您希望这是~/article，那么您需要更改路线顺序。此外，正如 Jan 建议的那样，您应该将默认 pageNumer 设置移动到另一条路线。我稍后会更新我的答案。

【解决方案2】：

你还没有告诉我们，什么是行不通的。我唯一看到的是，您为 pageNumber 参数设置了错误的值。

这应该会更好：

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" }
);

【讨论】：

在您的示例中，如果我调用Url.Action("Index", "MyController", new { pageNumber = 1 })，它将呈现为~/article/page-1，我希望它呈现为~/article
是的，将第一个的顺序改为路由。
