# 교차 출처 리소스 공유

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORS 또는 "교차-출처 리소스 공유"</a>란, 브라우저에서 동작하는 프론트엔드가 자바스크립트로 코드로 백엔드와 통신하고, 백엔드는 해당 프론트엔드와 다른 "출처"에 존재하는 상황을 의미합니다.

## 출처

출처란 프로토콜(`http` , `https`), 도메인(`myapp.com`, `localhost`, `localhost.tiangolo.com` ), 그리고 포트(`80`, `443`, `8080` )의 조합을 의미합니다.

따라서, 아래는 모두 상이한 출처입니다:

* `http://localhost`
* `https://localhost`

Если у вас есть другой сценарий, где нужно раннее завершение зависимости с `yield`, пожалуйста, создайте <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">вопрос в GitHub Discussions</a> с описанием конкретного кейса и почему вам было бы полезно иметь раннее закрытие для зависимостей с `yield`.

Si tienes una versión anterior, obtendrás errores al intentar usar `Annotated`.

Asegúrate de [Actualizar la versión de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} a al menos la 0.95.1 antes de usar `Annotated`.

///

## Declarar metadatos { #declare-metadata }

Puedes declarar todos los mismos parámetros que para `Query`.

Wenn Sie eine ältere Version haben, würden Fehler angezeigt werden, wenn Sie versuchen, `Annotated` zu verwenden.

Stellen Sie sicher, dass Sie [FastAPI aktualisieren](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank}, auf mindestens Version 0.95.1, bevor Sie `Annotated` verwenden.

///

## Metadaten deklarieren { #declare-metadata }

Sie können dieselben Parameter wie für `Query` deklarieren.
