[C#] 웹 API 넣기 요청이 Http 405 메소드 허용되지 않음 오류를 생성 함

다음 PUT은 내 웹 API 에서 메소드에 대한 호출입니다. 메소드의 세 번째 줄입니다 (ASP.NET MVC 프론트 엔드에서 웹 API를 호출합니다).

client.BaseAddress입니다 http://localhost/CallCOPAPI/.

여기 있습니다 contactUri:

여기 있습니다 contactUri.PathAndQuery:

마지막으로 405 응답입니다.

내 웹 API 프로젝트의 WebApi.config는 다음과 같습니다.

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

            config.Routes.MapHttpRoute(
                name: "DefaultApiGet",
                routeTemplate: "api/{controller}/{action}/{regionId}",
                defaults: new { action = "Get" },
                constraints: new { httpMethod = new HttpMethodConstraint("GET") });

            var json = config.Formatters.JsonFormatter;
            json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
            config.Formatters.Remove(config.Formatters.XmlFormatter);

나는에 전달되는 경로 아래로 제거 해봤 PutAsJsonAsync로 string.Format("/api/department/{0}", department.Id)하고 string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)행운과 함께합니다.

405 오류가 발생하는 이유를 아는 사람이 있습니까?
