Por exemplo, para declarar um outro retorno com o status code `404` e um modelo do Pydantic chamado `Message`, você pode escrever:

```Python hl_lines="18  22"
{!../../docs_src/additional_responses/tutorial001.py!}
```

/// note | "Nota"

Lembre-se que você deve retornar o `JSONResponse` diretamente.

///

/// info | "Informação"

A chave `model` não é parte do OpenAPI.

```Python hl_lines="11-15"
{!> ../../docs_src/dependencies/tutorial002.py!}
```

////

//// tab | 파이썬 3.10 이상

```Python hl_lines="9-13"
{!> ../../docs_src/dependencies/tutorial002_py310.py!}
```

////

클래스의 인스턴스를 생성하는 데 사용되는 `__init__` 메서드에 주목하기 바랍니다:

//// tab | 파이썬 3.6 이상

```Python hl_lines="12"
{!> ../../docs_src/dependencies/tutorial002.py!}
```

////

//// tab | 파이썬 3.10 이상

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial003.py!}
```

এডিটর ভেরিয়েবলগুলির টাইপ জানার কারণে, আপনি শুধুমাত্র অটোকমপ্লিশনই পান না, আপনি এরর চেকও পান:

এখন আপনি জানেন যে আপনাকে এটি ঠিক করতে হবে, `age`-কে একটি স্ট্রিং হিসেবে রূপান্তর করতে `str(age)` ব্যবহার করতে হবে:

```Python hl_lines="2"
{!../../docs_src/python_types/tutorial004.py!}
```

## টাইপ ঘোষণা

```Python hl_lines="1  18"

### `HTMLResponse`

Nimmt Text oder Bytes entgegen und gibt eine HTML-Response zurück, wie Sie oben gelesen haben.

### `PlainTextResponse`

Nimmt Text oder Bytes entgegen und gibt eine Plain-Text-Response zurück.

```Python hl_lines="2  7  9"
{!../../docs_src/custom_response/tutorial005.py!}
```

### `JSONResponse`

from fastapi.testclient import TestClient

from docs_src.extending_openapi.tutorial001 import app

client = TestClient(app)


def test():
    response = client.get("/items/")
    assert response.status_code == 200, response.text
    assert response.json() == [{"name": "Foo"}]


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {

    # ---------------------
    context.close()
    browser.close()


process = subprocess.Popen(
    ["fastapi", "run", "docs_src/cookie_param_models/tutorial001.py"]
)
try:
    for _ in range(3):
        try:
            response = httpx.get("http://localhost:8000/docs")
        except httpx.ConnectError:
            time.sleep(1)
            break

```

And then you can set the `status_code` in that *temporal* response object.

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.py!}
```

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

from fastapi.testclient import TestClient

from ...utils import needs_pydanticv2


@pytest.fixture(name="client")
def get_client() -> TestClient:
    from docs_src.separate_openapi_schemas.tutorial001 import app

    client = TestClient(app)
    return client


def test_create_item(client: TestClient) -> None:
    response = client.post("/items/", json={"name": "Foo"})
    assert response.status_code == 200, response.text

```

O **FastAPI** irá **extrair** os dados para **cada campo** dos **cookies** recebidos na requisição e lhe fornecer o modelo Pydantic que você definiu.
