## JSON Response'lar { #json-responses }

Varsayılan olarak FastAPI JSON response'lar döndürür.

Bir [Response Model](../tutorial/response-model.md) tanımlarsanız, FastAPI veriyi Pydantic kullanarak JSON’a serialize eder.

    response = client.post("/schema_extra/", json={"data": "Foo"})
    assert response.status_code == 200, response.text
    response = client.post("/example/", json={"data": "Foo"})
    assert response.status_code == 200, response.text
    response = client.post("/examples/", json={"data": "Foo"})
    assert response.status_code == 200, response.text
    response = client.post("/example_examples/", json={"data": "Foo"})

이를 위해 `jsonable_encoder`를 사용할 수 있습니다.

Pydantic 모델 같은 객체를 받고 JSON 호환 가능한 버전을 반환합니다:

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

이 예시에서는 Pydantic 모델을 `dict`로, `datetime`을 `str`로 변환합니다.

이렇게 호출한 결과는 파이썬 표준인 [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)로 인코딩할 수 있습니다.

JSON 형식(문자열)의 데이터가 들어있는 큰 `str`을 반환하지 않습니다. JSON과 모두 호환되는 값과 하위 값이 있는 파이썬 표준 데이터 구조(예: `dict`)를 반환합니다.

        "/items/5",

        },
    )

        "item_id": 5,
        "item": {

### JSON Schemas Feld `examples` { #json-schemas-examples-field }

Aber dann fügte JSON Schema ein [`examples`](https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5)-Feld zu einer neuen Version der Spezifikation hinzu.

Und dann basierte das neue OpenAPI 3.1.0 auf der neuesten Version (JSON Schema 2020-12), die dieses neue Feld `examples` enthielt.
