如何省略首页看法控制器名称 [英] How to omit controller name for Home views

问题描述

让我们说我有这样的结构：

     指数
    关于项目/
    指数
    细节
 

我怎么可以省略控制器名称为家庭的看法？

我想写 {根} /关于而不是 {根} /首页/关于。

我也想 {}根/项目/细节/ 2 工作

下面是我在尝试的RegisterRoutes ：

  routes.IgnoreRoute（{}资源个.axd / {*} PATHINFO）;routes.MapRoute（
    名称：默认路由
    网址：{控制器} / {行动} / {ID}
    默认：新
    {
        控制器=家，
        行动=索引，
        ID = UrlParameter.Optional
    }
）;routes.MapRoute（
    名称：HomeRoute
    网址：{}行动，
    默认：新
    {
        控制器=家，
        行动=索引
    }
）;
 

编辑：我也试过换我的图路线调用顺序，但它仍然无法正常工作结果
我需要的是：

  {}根/首页/索引＆gt; HomeController.Index
{}根/家庭＆GT; HomeController.Index
{}根与GT; HomeController.Index
{}根/主页/关于＆GT; HomeController.About
{}根/关于＆GT; HomeController.About
{}根/项目/索引＆gt; ProjectController.Index
{}根/项目＆GT; ProjectController.Index
{}根/项目/细节/ 12＆GT; ProjectController.Details
 

解决方案

只需更改顺序的图路线调用：

  routes.MapRoute（
    名称：HomeRoute
    网址：{}行动，
    默认：新{控制器=家，行动=索引}
）;routes.MapRoute（
    名称：默认，
    网址：{控制器} / {行动} / {ID}
    默认：新{控制器=家，行动=索引，ID = UrlParameter.Optional}
）;
 

在默认路线已被最后定义，否则它匹配所有的URL模式并没有进一步的路线进行评估。

更新：

根据您的编辑，因为你要preserve的控制器名称只是路线为好。试试这个：

 公共类ActionExistsConstraint：IRouteConstraint
{
    私人只读类型_controllerType;    公共ActionExistsConstraint（类型controllerType）
    {
        this._controllerType = controllerType;
    }    公共BOOL匹配（HttpContextBase HttpContext的，路由路径，字符串参数名称，RouteValueDictionary价值，RouteDirection routeDirection）
    {
        VAR actionName =值[行动]作为字符串;        如果（actionName == NULL || _controllerType == NULL || _controllerType.GetMethod（actionName，BindingFlags.Instance | BindingFlags.Public | BindingFlags.InvokeMethod | BindingFlags.IgnoreCase）== NULL）
            返回false;        返回true;
    }
}
 

然后：

  routes.MapRoute（
    名称：HomeRoute
    网址：{}行动，
    默认：新{控制器=家，行动=索引}，
    限制：新{存在=新ActionExistsConstraint（typeof运算（HomeController中））}
）;

Let's say I have this structure:

Home/
    Index
    About

Project/
    Index
    Details

How can I omit the controller name for Home views?

I want to write {root}/About instead of {root}/Home/About.
I also want {root}/Project/Details/2 to work.

Here is what I tried in RegisterRoutes:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

routes.MapRoute(
    name: "HomeRoute",
    url: "{action}",
    defaults: new
    {
        controller = "Home",
        action = "Index"
    }
);

Edit: I also tried swapping the order of my MapRoute calls but it still doesn't work.
What I need is:

{root}/Home/Index         > HomeController.Index
{root}/Home               > HomeController.Index
{root}                    > HomeController.Index
{root}/Home/About         > HomeController.About
{root}/About              > HomeController.About
{root}/Project/Index      > ProjectController.Index
{root}/Project            > ProjectController.Index
{root}/Project/Details/12 > ProjectController.Details

解决方案

Just change the order of your MapRoute calls:

routes.MapRoute(
    name: "HomeRoute",
    url: "{action}",
    defaults: new { controller = "Home", action = "Index" }
);

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

The 'Default' route has to be defined last, otherwise it matches all Url patterns and no further routes are evaluated.

Update:

As per your edit, since you want to preserve the 'controller-name-only' route as well. Try this:

public class ActionExistsConstraint : IRouteConstraint
{
    private readonly Type _controllerType;

    public ActionExistsConstraint(Type controllerType)
    {
        this._controllerType = controllerType;
    }

    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
    {
        var actionName = values["action"] as string;

        if (actionName == null || _controllerType == null || _controllerType.GetMethod(actionName, BindingFlags.Instance | BindingFlags.Public | BindingFlags.InvokeMethod | BindingFlags.IgnoreCase) == null)
            return false;

        return true;
    }
}

Then:

routes.MapRoute(
    name: "HomeRoute",
    url: "{action}",
    defaults: new { controller = "Home", action = "Index" },
    constraints: new { exists = new ActionExistsConstraint(typeof(HomeController)) }
);
