我做错了什么?正在尝试从API获取响应

我正在尝试从API获取任何响应。我读了很多书，但无论如何都会得到404（找不到资源）这是我的代码

Web.config:
<authentication mode="Forms">
    <forms loginUrl="~/Account/Login" defaultUrl="~/Home/Index">
    </forms>
</authentication>

Global.asax.cs

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

WebApiConfig.cs

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services
    // Web API routes

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

    // webapi return json
    // http://stackoverflow.com/questions/9847564/how-do-i-get-asp-net-web-api-to-return-json-instead-of-xml-using-chrome
    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
}

ApiController:

public class MyAppApiController : ApiController
{
    public HttpResponseMessage Test()
    {
        return Request.CreateResponse(HttpStatusCode.OK, new { Success = true, bbb = "assssdfv[spld[ssadf[ps" });
    }
    public HttpResponseMessage Login(LoginViewModel loginVM)
    {
        var url = this.Url.Link("Default", new { Controller = "AccountController", Action = "Login", model = loginVM});
        return Request.CreateResponse(HttpStatusCode.OK, new { Success = true, RedirectUrl = url });
    }
}

我正在使用Google Chrome Simple REST客户端进行测试：

1. 以管理员身份运行我的VS
2. 调试我的应用程序（localhost:12345与我的网站一起打开）

3. 粘贴在谷歌Chrome简单REST客户端：

   http://localhost:12345/api/Test   
   

   并运行GET=>结果404（未找到资源）

4. 粘贴在谷歌Chrome简单REST客户端：

   http://localhost:12345/api/Login 
   

   字段数据和标头无效，并运行POST=>结果404（未找到资源）

我的代码哪里有错？

更新：

我已更新：

   protected void Application_Start()
            {
                AreaRegistration.RegisterAllAreas();
                FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
                GlobalConfiguration.Configure(WebApiConfig.Register);
                RouteConfig.RegisterRoutes(RouteTable.Routes);
                BundleConfig.RegisterBundles(BundleTable.Bundles);
         //removed this: WebApiConfig.Register(GlobalConfiguration.Configuration);
            }

然后我的代码是

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

作品但我仍然得到404错误-但错误是新的：{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:12345/api/Login'.","MessageDetail":"No type was found that matches the controller named 'Login'."}我的控制器名称是

myProjApiController :ApiController

但是

http://localhost:12345/api/myProjApiController/Login'

结果：

404 No type was found that matches the controller named 'myProjApiController'
