ASP.NET MVC 自定义视图路由

Question

我们的解决方案层次结构如下：

控制器\类别\视图

例如： 控制器\数据分析\数据检索

现在我想映射路由，这样当用户在 url 中键入视图的名称时，它会自动将 url 映射到相应的控制器

IE: localhost:1234\DataAnalysis\DataRetrieve

应该映射到

查看\DataAnalysis\DataRetrieve\Index.cshtml

同样地，任何包含操作的 url 请求都应该检索相应的视图

IE: localhost:1234\DataAnalysis\DataRetrieve\TestAction

应该映射到

查看\DataAnalysis\DataRetrieve\TestAction.cshtml

目前，我们使用的是默认路由

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

这意味着如果我输入上面显示的 URL，它会忽略类别并且无法返回视图。

有没有办法自定义路由以获得上述行为？

为了根据 cmets 澄清我的问题，这是我的解决方案资源管理器的屏幕截图

现在，如果我调用 localhost:12346/DataAnalysis/DataRetrieve，这应该会将我带到索引。路由这不是问题，因为我可以这样做：

        routes.MapRoute(
            name: "ExampleRouting",
            url: "{category}/{controller}/{action}"
        );

但这就是问题所在。我还想像这样组织我的文件结构：

默认情况下，当我尝试检索 dataretrieve 的索引时，它会查看 Views\DataRetrieve\Index 而不是 Views\DataAnalysis\DataRetrieve\Index。

如何改变这种行为？

根据答案，我添加了一个自定义视图引擎，在 Application_Start 中注册它，更新了我的路由。仍然有同样的问题。

全球.asax

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        ViewEngines.Engines.Add(new SPCViewEngine());

        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
    }
}

RouteConfig.cs

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");


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

SPCViewEngine（自定义视图引擎）

public class SPCViewEngine : RazorViewEngine
{
    public SPCViewEngine()
        : base()
    {
        ViewLocationFormats = new[] {
            "~/Views/{1}/%1/{0}.cshtml",
            "~/Views/{1}/%1/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml",
            "~/Views/Shared/{0}.vbhtml"
        };

         PartialViewLocationFormats = new[] {
            "~/Views/%1/{1}/{0}.cshtml",
            "~/Views/%1/{1}/{0}.vbhtml",
            "~/Views/Shared/{0}.cshtml",
            "~/Views/Shared/{0}.vbhtml"
        };
    }

    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
    {
        var categoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreatePartialView(controllerContext, partialPath.Replace("%1", categoryName));
    }

    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
    {
        var categoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreateView(controllerContext, viewPath.Replace("%1", categoryName), masterPath);
    }

    protected override bool FileExists(ControllerContext controllerContext, string virtualPath)
    {
        var categoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.FileExists(controllerContext, virtualPath.Replace("%1", categoryName));
    }
}

如果我正确理解了您的问题，您可以创建自己的视图引擎，在运行时解析视图位置并插入您的应用程序。

创建您自己的自定义视图引擎。

    public class MyViewEngine : RazorViewEngine
{
    public MyViewEngine()
        : base()
    {
        ViewLocationFormats = new[] {
        "~/Views/{1}/%1/{0}.cshtml",
        "~/Views/{1}/%1/{0}.vbhtml",
        "~/Views/Shared/{0}.cshtml",
        "~/Views/Shared/{0}.vbhtml"
    };

    PartialViewLocationFormats = new[] {
        "~/Views/%1/{1}/{0}.cshtml",
        "~/Views/%1/{1}/{0}.vbhtml",
        "~/Views/Shared/{0}.cshtml",
        "~/Views/Shared/{0}.vbhtml"
    };
    }

    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreatePartialView(controllerContext, partialPath.Replace("%1", catagoryName));
    }

    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreateView(controllerContext, viewPath.Replace("%1", catagoryName),masterPath);
    }

    protected override bool FileExists(ControllerContext controllerContext, string virtualPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.FileExists(controllerContext, virtualPath.Replace("%1", catagoryName));
    }

}

在这里注册

protected void Application_Start()
{   
   AreaRegistration.RegisterAllAreas();

   RegisterGlobalFilters(GlobalFilters.Filters);
   RegisterRoutes(RouteTable.Routes);


   //Register your View Engine Here.
   ViewEngines.Engines.Add(new MyViewEngine());
}

更新路由配置，默认为

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