具有多个参数的 ASP.NET MVC 路由

Question

我有一个带有多个操作方法（

ManageController

和

Index

）的

Details

，其中有参数“group”和“key”，我想像这样设置我的链接：

http://localhost:49900/Manage/1
http://localhost:49900/Manage/Details/1/sample

但是链接是这样的

http://localhost:49900/Manage?group=1
http://localhost:49900/Manage/Details?group=1&key=sample

这是我的路由设置：

routes.MapRoute(
            name: "Manage",
            url: "{controller}/{action}/{group}",
            defaults: new { controller = "Manage", action = "Index", group = "" }
        );

routes.MapRoute(
            name: "ManageDetails",
            url: "{controller}/{action}/{group}/{key}",
            defaults: new { controller = "Manage", action = "Details", group = "", key = UrlParameter.Optional }
        );

控制器动作方法：

public ActionResult Index(string group)
{
    return View();
}

public ActionResult Details(string group, string key)
{
    return View();
}

行动链接：

<li>
    <a href="@Url.Action("Index", "Manage", new { group = "1" })">Manage</a>
</li>
<li>
    <a href="@Url.Action("Details", "Manage", new { group = "1", key = "sample" })">Manage Details</a>
</li>

考虑使用以下路线：

routes.MapRoute(
            name: "ManageDefault",
            url: "{controller}/{group}",
            defaults: new { controller = "Manage", action = "Index", group = "" }
        );
routes.MapRoute(
            name: "ManageDetails",
            url: "{controller}/{action}/{group}/{key}",
            defaults: new { controller = "Manage", action = "Details", group = "",
                            key = UrlParameter.Optional }
        );

您在

ManageDefault

路线声明中的问题：当使用像

"{controller}/{action}/{group}"

这样的格式时，它变得通用。因此，第二个模板永远不会发生。

与您的代码的区别仅在于删除第一个

{action}

中的

MapRoute()

部分。这应该服务于

http://localhost:49900/Manage/1

，同时第二个路由模板将用作默认值。
