Si abres en tu navegador una URL como:

```
http://127.0.0.1:8000/items/foo-item
```

...sin agregar el parámetro requerido `needy`, verás un error como:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Sie können den `jsonable_encoder` verwenden, um die empfangenen Daten in etwas zu konvertieren, das als JSON gespeichert werden kann (z. B. in einer NoSQL-Datenbank). Zum Beispiel, um ein `datetime` in einen `str` zu konvertieren.

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

As part of the application object creation, a *path operation* for `/openapi.json` (or for whatever you set your `openapi_url`) is registered.

It just returns a JSON response with the result of the application's `.openapi()` method.

/// tip | 팁

주목할 점은 타입, 기본 값 및 `Field`로 이루어진 각 모델 어트리뷰트가  `Path`, `Query`와 `Body`대신 `Field`를 사용하는 *경로 작동 함수*의 매개변수와 같은 구조를 가진다는 점 입니다.

## 별도 정보 추가

`Field`, `Query`, `Body`, 그 외 안에 별도 정보를 선언할 수 있습니다. 이는 생성된 JSON 스키마에 포함됩니다.

여러분이 예제를 선언할 때 나중에 이 공식 문서에서 별도 정보를 추가하는 방법을 배울 것입니다.

/// warning | 경고

별도 키가 전달된 `Field` 또한 여러분의 어플리케이션의 OpenAPI 스키마에 나타날 것입니다.
