Extra-Schlüssel, die `Field` überreicht werden, werden auch im resultierenden OpenAPI-Schema Ihrer Anwendung gelistet. Da diese Schlüssel nicht notwendigerweise Teil der OpenAPI-Spezifikation sind, könnten einige OpenAPI-Tools, wie etwa [der OpenAPI-Validator](https://validator.swagger.io/), nicht mit Ihrem generierten Schema funktionieren.

## Zusammenfassung

Sie können Pydantics `Field` verwenden, um zusätzliche Validierungen und Metadaten für Modellattribute zu deklarieren.

	}

		v, _, _, err = env.LookupEnv(config.EnvVolumes)
		if err != nil {

	sseCfg, _, err := globalBucketMetadataSys.GetSSEConfig(bucket)
	return sseCfg, err
}

// validateBucketSSEConfig parses bucket encryption configuration and validates if it is supported by MinIO.
func validateBucketSSEConfig(r io.Reader) (*sse.BucketSSEConfig, error) {
	encConfig, err := sse.ParseBucketSSEConfig(r)
	if err != nil {
		return nil, err
	}

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## Recap { #recap }

You can use Pydantic's `Field` to declare extra validations and metadata for model attributes.

 * This class is used to encapsulate the header information for HTTP requests.
 * It provides methods to get and set the name and value of the header,
 * as well as a method to validate the header.
 *
 * <p>Example usage:</p>
 * <pre>
 *     RequestHeader header = new RequestHeader("Content-Type", "application/json");
 *     String name = header.getName();
 *     String value = header.getValue();

여러분이 예제를 선언할 때 나중에 이 공식 문서에서 별도 정보를 추가하는 방법을 배울 것입니다.

/// warning | 경고

별도 키가 전달된 `Field` 또한 여러분의 어플리케이션의 OpenAPI 스키마에 나타날 것입니다.
이런 키가 OpenAPI 명세서, [the OpenAPI validator](https://validator.swagger.io/)같은 몇몇 OpenAPI 도구들에 포함되지 못할 수 있으며, 여러분이 생성한 스키마와 호환되지 않을 수 있습니다.

## 요약

모델 어트리뷰트를 위한 추가 검증과 메타데이터 선언하기 위해 Pydantic의 `Field` 를 사용할 수 있습니다.

Поскольку эти ключи не являются обязательной частью спецификации OpenAPI, некоторые инструменты OpenAPI, например, [валидатор OpenAPI](https://validator.swagger.io/), могут не работать с вашей сгенерированной схемой.

## Резюме

Вы можете использовать функцию `Field` из Pydantic, чтобы задавать дополнительную валидацию и метаданные для атрибутов модели.
