我无法访问我的ApiController

我正在尝试创建一个用于登录的Api控制器，在使用我的CustomerController（Api）访问数据之前应使用该控制器。

问题是，当我尝试访问上的登录方法时，出现404错误AccountController。我正在尝试发布到，AccountController如下面的屏幕快照所示。

有趣的是，CustomerController通过将浏览器指向，我可以毫无问题地访问（Api）http://localhost:62655/api/customer/cvr/88888888。我是否缺少POST请求的约定或内容？

我的WebApi路由配置为：

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

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

并添加到我的Global.asax中：

WebApiConfig.Register(GlobalConfiguration.Configuration);

我的AccountController和CustomerController看起来像这样（为简洁起见，合并了文件）：

public class AccountController : ApiController
{
    public UserManager<ApplicationUser> UserManager { get; private set; }
    private IAuthenticationManager AuthenticationManager
    {
        get
        {
            return HttpContext.Current.GetOwinContext().Authentication;
        }
    }

    public AccountController(UserManager<ApplicationUser> userManager)
    {
        UserManager = userManager;
    }

    public async Task<HttpResponseMessage> Login([FromBody]LoginApiViewModel model)
    {
        if (!ModelState.IsValid) return Request.CreateResponse(HttpStatusCode.BadRequest, "Username or password is not supplied");

        var user = UserManager.Find(model.Username, model.Password);
        if (user != null && UserManager.IsInRole(user.Id, "Administrator"))
        {
            var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
            AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = true }, identity);

            var response = Request.CreateResponse(HttpStatusCode.OK, "Success");
            return response;
        }

        return Request.CreateResponse(HttpStatusCode.Unauthorized, "Wrong login");
    }
}

[Authorize(Roles = "Administrator")]
public class CustomerController : ApiController
{
    private readonly ICustomerService _customerService;

    public CustomerController(ICustomerService customerService)
    {
        _customerService = customerService;
    }

    [ActionName("cvr")]
    public CustomerApiViewModel GetCustomerById(string id)
    {
       var customer = _customerService.GetByCVR(id);
       if (customer == null) throw new HttpResponseException(HttpStatusCode.NotFound);
       var customerViewModel = Mapper.Map<CustomerApiViewModel>(customer);

       return customerViewModel;
    }
}

上图返回404错误。该程序是Fiddler2。

例外：

[HttpException]：找不到路径'/ api / account / login'的控制器或未实现IController。

基于注释，更新-（完整的Global.asax和RouteConfig（MVC）

 protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    GlobalConfiguration.Configure(WebApiConfig.Register);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
    AutoMapperWebConfiguration.Configure();

    GlobalConfiguration.Configuration.EnsureInitialized(); 
}

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

    routes.MapRoute(
        "DefaultOnlyAction",
        "{action}",
        new { controller = "Home", action = "Index" }
    );

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