REST 服务错误 405：方法不允许

Question

My Get Works perfectly, but my update and delete give me 405 Errors. Here is my Web.config and Controller. Sorry for the bad formatting. I've tried a lot of different thing but I am unsure why I am getting 405 Errors. my app works with my other REST Service so I know it can perform CRUD and that the issue is my Service.

Here is my Controller

public class ResponseItemsController : BaseApiController

    static readonly IwellService wellService = new wellService(new 
    wellRepository());

    [HttpGet]
    [BasicAuthentication(RequireSsl = false)]

        wellService.GetData());
    }

    [HttpPost]
    [BasicAuthentication(RequireSsl = false)]
    public HttpResponseMessage Create([FromBody]ResponseItem item)

                string.IsNullOrWhiteSpace(item.Name__c) ||
                string.IsNullOrWhiteSpace(item.Question_1__c))

            }
            wellService.InsertData(item);
        }
        catch (Exception)
        {
            return base.BuildErrorResult(HttpStatusCode.BadRequest, ErrorCode.CouldNotCreateItem.ToString());
        }

        return base.BuildSuccessResult(HttpStatusCode.Created);
    }

    [HttpPut]

            var wellItem = wellService.Find(id);
            if (wellItem != null)
            {
                wellService.UpdateData(item);
            }
            else

                return base.BuildErrorResult(HttpStatusCode.NotFound, ErrorCode.RecordNotFound.ToString());
            }
        }
        catch (Exception)

        }

        return base.BuildSuccessResult(HttpStatusCode.NoContent);
    }

    [HttpDelete]
    [BasicAuthentication(RequireSsl = false)]

        }

        return base.BuildSuccessResult(HttpStatusCode.NoContent);
    }
}

}

Here is my routing WebApiconfig/Routeconfig. I've tried using [Route("api/responseitems/")] for the controller and then [Route("api/responseitems/{id}")] for the methods but same issue of 405 errors. My written in exceptions are codes are just 404,400,200.

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
        // Web API routes
        config.MapHttpAttributeRoutes();

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


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

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

I think the issue is with your calling mechanism from your application. Can you use correct Http verb while calling your API.

Or place your complete endpoints with your method type so that I may further help you out.
