asp.net-mvc - 将属性路由添加到现有 MVC 5 Web 应用程序时，什么会导致属性路由不起作用？

Question

我添加了 Web API nuget 和通过 Global.asax 调用 MapHttpAttributeRoutes 的 StartUp WebApiConfig 代码，但所有属性路由都不起作用。

protected void Application_Start()
{
    SqlServerTypes.Utilities.LoadNativeAssemblies(Server.MapPath("~/bin"));

    MvcHandler.DisableMvcResponseHeader = true;

    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
}

这是安装的包。

Controller 代码

[Authorize(Roles = "Admin")]
[RoutePrefix("admin/api/v/{vid}/photos")]
public class PhotosController : ApiController
{
    [AllowAnonymous]
    [Route("test", Name="Test")]
    [HttpGet]
    public IHttpActionResult Test(string vid)
    {
        return Ok();
    }
}

我知道发生了什么，我有两个同名的 Api Controller 。看起来 Web Api 属性路由不会像 MVC 那样区分具有 namespace 约束的操作和 Controller 。我只是将 Admin 添加到控件类名称的前面，现在一切似乎都正常了。
