# Configuración Avanzada de Path Operation

## operationId de OpenAPI

Si no eres un "experto" en OpenAPI, probablemente no necesites esto.

Puedes establecer el `operationId` de OpenAPI para ser usado en tu *path operation* con el parámetro `operation_id`.

Tienes que asegurarte de que sea único para cada operación.

## OpenAPI operationId

/// warning | Achtung

Wenn Sie kein „Experte“ für OpenAPI sind, brauchen Sie dies wahrscheinlich nicht.

///

Mit dem Parameter `operation_id` können Sie die OpenAPI `operationId` festlegen, die in Ihrer *Pfadoperation* verwendet werden soll.

Sie müssten sicherstellen, dass sie für jede Operation eindeutig ist.

## `Field` importieren

Importieren Sie es zuerst:

/// warning | Achtung

Beachten Sie, dass `Field` direkt von `pydantic` importiert wird, nicht von `fastapi`, wie die anderen (`Query`, `Path`, `Body`, usw.)

`Body` 및 `Query`와 동일한 방식으로 파일과 폼의 매개변수를 생성합니다:

{* ../../docs_src/request_forms_and_files/tutorial001.py hl[8] *}

파일과 폼 필드는 폼 데이터 형식으로 업로드되어 파일과 폼 필드로 전달됩니다.

어떤 파일들은 `bytes`로, 또 어떤 파일들은 `UploadFile`로 선언할 수 있습니다.

/// warning | 경고

다수의 `File`과 `Form` 매개변수를 한 *경로 작동*에 선언하는 것이 가능하지만, 요청의 본문이 `application/json`가 아닌 `multipart/form-data`로 인코딩 되기 때문에 JSON으로 받아야하는 `Body` 필드를 함께 선언할 수는 없습니다.

이는 **FastAPI**의 한계가 아니라, HTTP 프로토콜에 의한 것입니다.
