找不到与名为"User"的控制器匹配的类型

Question

我正在尝试导航到一个页面,其URL的格式如下:localhost:xxxxx/User/{id}/VerifyEmail？secretKey = xxxxxxxxxxxxxxx

我在RouteConfig.cs文件中添加了一个新路由,所以我RouteConfig.cs看起来像这样:

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

        routes.MapRoute(
            name: "VerifyEmail",
            url: "User/{id}/VerifyEmail",
            defaults: new { controller = "User", action = "VerifyEmail" }
        );

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

不幸的是,当我尝试导航到该URL时,我得到了这个页面:

<Error>
    <Message>
        No HTTP resource was found that matches the request URI 'http://localhost:52684/User/f2acc4d0-2e03-4d72-99b6-9b9b85bd661a/VerifyEmail?secretKey=e9bf3924-681c-4afc-a8b0-3fd58eba93fe'.
    </Message>
    <MessageDetail>
        No type was found that matches the controller named 'User'.
    </MessageDetail>
</Error>

这是我的UserController:

public class UserController : Controller
{

    // GET      /User/{id}/VerifyEmail
    [HttpGet]
    public ActionResult VerifyEmail(string id, string secretKey)
    {
        try
        {
            User user = UsersBL.Instance.Verify(id, secretKey);
            //logger.Debug(String.Format("User %s just signed-in in by email.",
                user.DebugDescription()));
        }
        catch (Exception e)
        {
            throw new Exception("Failed", e);
        }
        return View();
    }
}

请告诉我,我做错了什么？

Answer 1

在我的例子中,控制器被定义为:

    public class DocumentAPI : ApiController
    {
    }

将其更改为以下工作!

    public class DocumentAPIController : ApiController
    {
    }

类名必须以Controller结束!

编辑:正如@Corey Alix建议的那样,请确保控制器具有公共访问修饰符; 路由处理程序忽略非公共控制器!

在我的情况下花了差不多30分钟试图解决问题后,我发现了导致它的原因:

我定义的路线WebApiConfig.cs是这样的:

config.Routes.MapHttpRoute(
    name: "ControllersApi",
    routeTemplate: "{controller}/{action}"
);

它应该是这样的:

config.Routes.MapHttpRoute(
    name: "ControllersApi",
     routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }
);

如你所见,它干扰了中定义的标准路线RouteConfig.cs.

另一种解决方案是将控制器类权限设置为public.

设置这个:

class DocumentAPIController : ApiController
{
}

至:

public class DocumentAPIController : ApiController
{
}

Answer 4

在我的情况下,我使用Web API,我没有public为我的控制器类定义.

要检查Web API的事情:

• 控制器类声明为 public
• Controller类实现了ApiController : ApiController
• 控制器类名称需要以 Controller
• 检查您的网址是否有/api/前缀.例如.'主机:端口/ API/{控制器}/{actionMethod}'

Answer 5

在我的情况下,我想创建一个Web API控制器,但由于疏忽,我的控制器继承自Controller而不是ApiController.

Answer 6

就我而言，路由定义为：

 config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{*catchall}",
            defaults: new { controller = "WarehouseController" }

而Controller需要在配置中删除：

 config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{*catchall}",
            defaults: new { controller = "Warehouse" }
