asp.net-mvc-5 - web api 2区域路由

Question

我正在使用 asp.net mvc 5 和 web api 2。对于 asp.net mvc 5 项目，我一切正常……但是新的我正在尝试添加 web api 2 路由……当我使用区域时。

我有 web api 2 Controller 在项目根目录下工作:

 //this is working 
   namespace EtracsWeb.Controllers
    {
        public class TestController : ApiController
        {
            //localhost:port/api/test ...this is working
            [HttpGet]
            public HttpResponseMessage Get()
            {

                return new HttpResponseMessage()
                {
                    Content = new StringContent("GET: Test message")
                };
            }

        }
    }

所以我假设我的 Global.asax , 我的 routeconfig.cs和我的 webapiconfig.cs是正确的......(未显示)......

但现在我正试图让我的区域中的 web api 2 工作......

我已经阅读了我可以在网上找到的所有内容，这似乎应该
工作:

namespace EtracsWeb.Areas.WorkOrder
{
    public class WorkOrderAreaRegistration : AreaRegistration
    {
        public override string AreaName
        {
            get
            {
                return "WorkOrder";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context)
        {

            context.Routes.MapHttpRoute(
                    name: "AuditModel_Api",
                    routeTemplate: "WorkOrder/api/AuditModelApi/{id}",
                    defaults: new { id = RouteParameter.Optional }
                );

        //default
            context.Routes.MapHttpRoute(
                    name: "WorkOrder_Api",
                    routeTemplate: "WorkOrder/api/{controller}/{id}",
                    defaults: new { id = RouteParameter.Optional }
                );

            context.MapRoute(
                 "WorkOrder_default",
                "WorkOrder/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

我的 Controller 代码是:

namespace EtracsWeb.Areas.WorkOrder.ApiControllers
{
    public class AuditModelApiController : ApiController
    {
        IManufacturerStopOrderModelService auditModelService = new WorkOrder.Services.VWAuditModelService(UserSession.EtracsUserID, UserSession.ProgramID, UserSession.EtracsSessionID, UserSession.ConnectionString);

        [HttpGet]
        [Route("AuditModelApi")]
        public HttpResponseMessage Get()
        {

            return new HttpResponseMessage()
            {
                Content = new StringContent("GET: Test message")
            };
        }

        [Route("AuditModelApi/AuditModels")]
        public IEnumerable<VwAuditModel1> GetAuditModels()
        {
                return auditModelService.GetModels();
        }

        public IHttpActionResult UpdateAuditMode()
        {
            //example of what can be returned ... NotFound, Ok ... look into uses...

            VwAuditModel1 result = new VwAuditModel1();
            return Ok(result);

            return NotFound();
        }
    }
}

我已经尝试了带和不带属性命名的 Controller [Route] ...
我无法开始工作......

无论是简单的情况

    public HttpResponseMessage Get()

和“真实”案例

  public IEnumerable<VwAuditModel1> GetAuditModels()

返回相同的结果。从浏览器，使用

http://localhost:64167/WorkOrder/api/AuditModelApi

和

http://localhost:64167/WorkOrder/api/AuditModelApi/AuditModels

我得到以下信息:

<Error>
<Message>
No HTTP resource was found that matches the request URI 'http://localhost:64167/WorkOrder/api/AuditModelApi/AuditModels'.
</Message>
<MessageDetail>
No route providing a controller name was found to match request URI 'http://localhost:64167/WorkOrder/api/AuditModelApi/AuditModels'
</MessageDetail>
</Error>

您需要获取 HttpConfiguration来自 GlobalConfiguration 的实例对象并调用 MapHttpAttributeRoutes()来自 RegisterArea() 内部的方法AreaRegistration.cs的方法.

    public override void RegisterArea(AreaRegistrationContext context) 
    {
        GlobalConfiguration.Configuration.MapHttpAttributeRoutes();

        //... omitted code  
    }

最后你必须在 WebApiConfig删除 config.MapHttpAttributes()方法，否则您将收到重复的异常。

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        config.EnableCors();

        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));


        // Web API routes
        //config.MapHttpAttributeRoutes();

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