ICollection에서 엔티티와 관련 객체를 유지하려고합니다.Web Api OData 내비게이션 속성에 게시
System.Data.Services.Client.DataServiceRequestException : System.Data.Services.Client.DataServiceClientException : 없음 HTTP 리소스가 요청 URI 일치를 찾을 수 없습니다 '서비스 오류 메시지 (제거 서버 이름)입니다 .Facade.Reports/odata/Reports (8236)/LayoutData '를 선택하십시오.
템플릿 '~/entityset/key/navigation'을 사용하여 OData 경로에 대한 작업을 선택하는 라우팅 규칙이 없습니다.
일부 테스트 클라이언트 코드 :
string uriString = "Service.Facade.Reports/odata/";
Uri uri = new Uri(uriString);
DataServiceContext context = new DataServiceContext(uri, DataServiceProtocolVersion.V3);
var layoutData = new ReportLayoutData { Data = new byte[] { 1, 2, 3 } };
var list = new List<ReportLayoutData>();
list.Add(layoutData);
var report = new ReportLayout { LayoutData = list, Name = "thing" };
context.AddObject("Reports", report);
context.AddRelatedObject(report, "LayoutData", list[0]); //Newly Added for Web API
DataServiceResponse response = context.SaveChanges();
호출없이 서비스를 AddRelatedObject하는 보고서를 추가로 사용할 수 있습니다. 그러나 탐색 속성은 서비스를 단계별로 실행할 때 자동으로 직렬화되지 않으므로 AddRelatedObject를 추가 한 것입니다. 이전에이 동일한 코드가 WCF Data Services에서 작동 (AddRelatedObject없이)되었으며 이제는 Web API로 변환하려고합니다. 내가이 무슨 생각 인 라우팅 규칙을 추가해야 할 것 같다 서비스 수준에서
:
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<ReportLayout>("Reports");
builder.EntitySet<ReportLayoutData>("ReportLayoutData");
builder.EntitySet<DatabaseInstance>("DataSources");
builder.EntitySet<DataSourceObject>("DataSourceObject");
config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel());
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
내가 POST를 지원하기 위해 내 컨트롤러에이 추가 된/탐색 속성에 넣습니다.
// POST PUT odata/Reports(5)/LayoutData
