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} al menos a la 0.95.1 antes de usar `Annotated`.

Se você tiver um caso diferente que precise sair antecipadamente de uma dependência com `yield`, por favor crie uma <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">Pergunta no GitHub Discussions</a> com o seu caso específico e por que você se beneficiaria de ter o fechamento antecipado para dependências com `yield`.

Wenn Sie einen anderen Anwendungsfall haben, der ein frühes Beenden aus einer Abhängigkeit mit `yield` benötigt, erstellen Sie bitte eine <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">GitHub-Diskussion-Frage</a> mit Ihrem spezifischen Anwendungsfall und warum Sie von einem frühen Schließen für Abhängigkeiten mit `yield` profitieren würden.

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

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

## `main.py`を作成

`main.py`に、下記の例をコピーします:

{* ../../docs_src/security/tutorial001.py *}

## 実行

/// info | 情報

まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`。
