from fastapi.testclient import TestClient

from docs_src.path_operation_advanced_configuration.tutorial002 import app

client = TestClient(app)


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


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

Aber FastAPI unterstützt auf die gleiche Weise auch die Verwendung von <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>:

```Python hl_lines="1  7-12  19-20"
{!../../docs_src/dataclasses/tutorial001.py!}
```

Schauen wir uns das vorherige Beispiel noch einmal an:

{* ../../docs_src/response_status_code/tutorial001.py hl[6] *}

`201` ist der Statuscode für „Created“ („Erzeugt“).

Aber Sie müssen sich nicht daran erinnern, welcher dieser Codes was bedeutet.

Sie können die Hilfsvariablen von `fastapi.status` verwenden.

{* ../../docs_src/response_status_code/tutorial002.py hl[1,6] *}

Рассмотрим предыдущий пример еще раз:

```Python hl_lines="6"
{!../../docs_src/response_status_code/tutorial001.py!}
```

`201` – это код статуса "Создано".

Но вам не обязательно запоминать, что означает каждый из этих кодов.

Для удобства вы можете использовать переменные из `fastapi.status`.

```Python hl_lines="1  6"
{!../../docs_src/response_status_code/tutorial002.py!}
```

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

```Python hl_lines="1  3  12-16"
{!../../docs_src/extra_data_types/tutorial001.py!}
```

Note que os parâmetros dentro da função tem seu tipo de dados natural, e você pode, por exemplo, realizar manipulações normais de data, como:

```Python hl_lines="18-19"
