c# - ASP.NET MVC 路由不工作

Question

我的路由工作不正常。我定义了以下路线:

routes.MapRoute(
     name: "CategoryDetails",
     url: "{seoName}",
     defaults: new { controller = "Category", action = "Details" }
);

routes.MapRoute(
     name: "ContactUs",
     url: "contact",
     defaults: new { controller = "Home", action = "Contact" }
);

routes.MapRoute(
     name: "AboutUs",
     url: "about",
     defaults: new { controller = "Home", action = "About" }
);

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

当我点击关于我们或联系我们的链接时，它会将我带到类别 Controller 中的详细操作方法。

这是我的关于我们和联系我们链接的标记:

@Html.ActionLink("About", "About", "Home")
@Html.ActionLink("Contact", "Contact", "Home")

我的类别 Controller 的详细操作方法:

public ActionResult Details(string seoName)
{
     CategoryViewModel model = categoryTask.Details(seoName);

     return View(model);
}

我的路由配置有什么问题？

将您的路线从最具体到不太具体重新排序。这样 contact 和 about 的路由就会出现在 seoName 路由之前:

routes.MapRoute(
        name: "ContactUs",
        url: "contact",
        defaults: new { controller = "Home", action = "Contact" }
);

routes.MapRoute(
        name: "AboutUs",
        url: "about",
        defaults: new { controller = "Home", action = "About" }
);

routes.MapRoute(
        name: "CategoryDetails",
        url: "{seoName}",
        defaults: new { controller = "Category", action = "Details" }
);

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

对于您的原始订单，urls~/contact 和 ~/about 将始终由 seoName 路由处理。通过对它们重新排序，您可以确保它们由 HomeController 中的正确操作处理，并且 seoName 路由将仅在联系人和 about 路由匹配失败后匹配 url。
