`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] *}

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>:

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

Рассмотрим предыдущий пример еще раз:

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

`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`.

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

<div class="termy">

```console
// Here we don't set the env var yet
$ python main.py

// As we didn't set the env var, we get the default value

Hello World from Python

// But if we create an environment variable first
$ export MY_NAME="Wade Wilson"

// And then call the program again
$ python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python
```

</div>

# Sorgu Parametreleri

Fonksiyonda yol parametrelerinin parçası olmayan diğer tanımlamalar otomatik olarak "sorgu" parametresi olarak yorumlanır.

Sorgu, bağlantıdaki `?` kısmından sonra gelen ve `&` işareti ile ayrılan anahtar-değer çiftlerinin oluşturduğu bir kümedir.

Örneğin, aşağıdaki bağlantıda:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...sorgu parametreleri şunlardır:

Puedes declarar un parámetro de tipo `Response` en tu *path operation function*.

Y luego puedes establecer cookies en ese objeto de response *temporal*.

{* ../../docs_src/response_cookies/tutorial002.py hl[1, 8:9] *}

Y entonces puedes devolver cualquier objeto que necesites, como normalmente lo harías (un `dict`, un modelo de base de datos, etc).
