Aber konzentrieren wir uns zunächst auf die spezifischen Details, die wir benötigen.

///

{* ../../docs_src/security/tutorial003_an_py310.py hl[87] *}

/// tip | Tipp

Gemäß der Spezifikation sollten Sie ein JSON mit einem `access_token` und einem `token_type` zurückgeben, genau wie in diesem Beispiel.

Pero por ahora, enfoquémonos en los detalles específicos que necesitamos.

///

{* ../../docs_src/security/tutorial003_an_py310.py hl[87] *}

/// tip | Consejo

De acuerdo con la especificación, deberías devolver un JSON con un `access_token` y un `token_type`, igual que en este ejemplo.

text_type = "text/plain; charset=utf-8"
html_type = "text/html; charset=utf-8"
override_type = "application/x-override"


def test_app():
    with client:
        response = client.get("/")
    assert response.json() == {"msg": "Hello World"}
    assert response.headers["content-type"] == orjson_type


def test_app_override():
    with client:
        response = client.get("/override")

Потім, якщо ви перейдете за URL `/openapi.json`, `/docs` або `/redoc`, ви просто отримаєте помилку `404 Not Found` на кшталт:

```JSON

    "detail": "Not Found"

	lines    = "lines"

	defaultRecordDelimiter = "\n"
)

// ReaderArgs - represents elements inside <InputSerialization><JSON/> in request XML.

	ContentType string `xml:"Type"`

## Несколько параметров тела запроса { #multiple-body-parameters }

В предыдущем примере, *операции пути* ожидали тело запроса в формате JSON, с параметрами, соответствующими атрибутам `Item`, например:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```
