в моем. net Core 3.0 Api Атрибут [JsonIgnore] не работает как исключение. Я использую System.Text.Json
вместо старого Newtonsoft.Json
Когда я использую свой ресурс, который возвращает список объектов, например:
/api/Object/
объекты сериализуются следующим образом:
[
{
"id": 1,
"date": "2020-02-12T08:45:51.502",
"userId": 1,
"tags": [
{
"name": "string"
}
]
}
]
Но когда я запрашиваю один результат
/api/Object/{id}
, полный объект сериализуется следующим образом:
{
"user": {
"hasAccess": false,
"id": 1,
"userName": "***",
"normalizedUserName": "***",
"email": "***",
"normalizedEmail": "***",
"emailConfirmed": true,
"passwordHash": "***",
"concurrencyStamp": "***",
"phoneNumberConfirmed": false,
"twoFactorEnabled": false,
"lockoutEnabled": true,
"accessFailedCount": 0
},
"lazyLoader": {},
"id": 1,
"date": "2020-02-12T08:45:51.502",
"userId": 1,
"tags": [
{
"name": "string"
}
]
}
класс с атрибутом JsonIgnore выглядит следующим образом:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Text.Json.Serialization;
public class Object
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public DateTime Date { get; set; }
[ForeignKey("User")]
public int UserId { get; set; }
[JsonIgnore]
public virtual User User { get; set; }
}
Это мой класс контроллера WebApi:
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using Models;
using Services;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
[Route("api/object")]
[ApiController]
[Authorize(Roles = Roles.ACCESS_GRANTED)]
public class ObjectController : AbstractController
{
private readonly ObjectService objectService;
public ObjectController(IDataService<Object> service, ExtendedUserManager manager) : base(manager)
{
objectService = (ObjectService)service;
}
// GET: api/Object
[HttpGet]
public IActionResult Get()
{
List<Object> object = objectService.GetAll();
return Ok(object);
}
// GET: api/Object/5
[HttpGet("{id}", Name = "GetObject")]
public IActionResult Get(int id)
{
Object object = objectService.Get(id);
if (object == null)
{
return NotFound(string.Format("Object with Id {0} could not be found", id));
}
return Ok(object);
}
}

Я что-то упустил или это ошибка?
Обновление:
Я заметил другое странное поведение, когда я возвращаюсь Недавно созданный объект вместо объекта из базы данных, все отлично работает.
[HttpGet("{id}", Name = "GetObject")]
public IActionResult Get(int id)
{
// Object object= objectService.Get(id);
Object object= new Object ();
object.User = new User();
if (object== null)
{
return NotFound(string.Format("object with Id {0} could not be found", id));
}
return Ok(object);
}
