- Вона також оголошує необов'язкове кукі `last_query` типу `str`.
    - Якщо користувач не надав параметр запиту `q`, ми використовуємо останній запит, який зберегли раніше в кукі.

## Використання залежності { #use-the-dependency }

Потім ми можемо використати залежність так:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

/// info | Інформація

### Valores de retorno { #return-values }

Y pueden devolver valores o no, los valores no serán usados.

Así que, puedes reutilizar una dependencia normal (que devuelve un valor) que ya uses en otro lugar, y aunque el valor no se use, la dependencia será ejecutada:

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[11,16] *}

## Dependencias para un grupo de *path operations* { #dependencies-for-a-group-of-path-operations }

# 응답 쿠키 { #response-cookies }

## `Response` 매개변수 사용하기 { #use-a-response-parameter }

*경로 처리 함수*에서 `Response` 타입의 매개변수를 선언할 수 있습니다.

그런 다음 해당 *임시* 응답 객체에서 쿠키를 설정할 수 있습니다.

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

그런 다음 일반적으로 하듯이 필요한 어떤 객체든 반환할 수 있습니다(`dict`, 데이터베이스 모델 등).

그리고 `response_model`을 선언했다면 반환한 객체를 거르고 변환하는 데 여전히 사용됩니다.

## Otimizar Desempenho da Resposta - Modelo de Resposta - Tipo de Retorno { #optimize-response-performance-response-model-return-type }

Para otimizar o desempenho ao retornar dados JSON, use um tipo de retorno ou modelo de resposta; assim, o Pydantic fará a serialização para JSON no lado do Rust, sem passar pelo Python. Leia mais na documentação de [Tutorial - Modelo de Resposta - Tipo de Retorno](../tutorial/response-model.md).

Luego convertirá y validará los datos. Así que, cuando uses ese objeto `settings`, tendrás datos de los tipos que declaraste (por ejemplo, `items_per_user` será un `int`).

### Usar el `settings` { #use-the-settings }

Luego puedes usar el nuevo objeto `settings` en tu aplicación:

{* ../../docs_src/settings/tutorial001_py310.py hl[18:20] *}

### Ejecutar el servidor { #run-the-server }
