* IDE warnings become more accurate, reducing warnings fatigue.
* Public API nullability annotations become closer to reality.
* Java compilation of Gradle code suffers from small performance penalty (up to 10%).
* Time has to be allocated to clean up existing projects.
* One has to write NullAway-conformant code even when hacking.
* Some patterns used to satisfy NullAway can be slightly more verbose.

## Agregar más validaciones { #add-more-validations }

También puedes agregar un parámetro `min_length`:

{* ../../docs_src/query_params_str_validations/tutorial003_an_py310.py hl[10] *}

## Agregar expresiones regulares { #add-regular-expressions }

Você pode utilizar a configuração do modelo Pydantic para `proibir` qualquer campo `extra`:

{* ../../docs_src/cookie_param_models/tutorial002_an_py310.py hl[10] *}

Se o cliente tentar enviar alguns **cookies extras**, eles receberão um retorno de **erro**.

따라서, `User_Agent` 등과 같이 첫 문자를 대문자화할 필요없이 파이썬 코드에서처럼 `user_agent`로 사용합니다.

만약 언더스코어를 하이픈으로 자동 변환을 비활성화해야 할 어떤 이유가 있다면, `Header`의 `convert_underscores` 매개변수를 `False`로 설정하십시오:

{* ../../docs_src/header_params/tutorial002.py hl[10] *}

/// warning | 경고

`convert_underscore`를 `False`로 설정하기 전에, 어떤 HTTP 프록시들과 서버들은 언더스코어가 포함된 헤더 사용을 허락하지 않는다는 것을 명심하십시오.

## 중복 헤더

중복 헤더들을 수신할 수 있습니다. 즉, 다중값을 갖는 동일한 헤더를 뜻합니다.
