/// info

FastAPI a ajouté le support pour `Annotated` (et a commencé à le recommander) dans la version 0.95.0.

Si vous avez une version plus ancienne, vous obtiendrez des erreurs en essayant d'utiliser `Annotated`.

Assurez-vous de [Mettre à jour la version de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} à la version 0.95.1 à minima avant d'utiliser `Annotated`.

///

## Déclarer des métadonnées

Se você tiver uma versão mais antiga, verá erros ao tentar usar `Annotated`.

Certifique-se de [Atualizar a versão do FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} para pelo menos 0.95.1 antes de usar `Annotated`.

///

## Declare metadados { #declare-metadata }

Você pode declarar todos os mesmos parâmetros que em `Query`.

    // non-hacky way (i.e. using String value class names- "[L...")?
    return Array.newInstance(componentType, 0).getClass();
  }

  /*
   * TODO(benyu): Once behavior is the same for all Java (and Android) versions we support, delete
   * this. It is possible that one or both of JAVA6 and JAVA7 have become unnecessary already.

Die gebräuchlichste Methode besteht darin, eine Datei `requirements.txt` mit den Namen der Packages und deren Versionen zu erstellen, eine pro Zeile.

Sie würden natürlich die gleichen Ideen verwenden, die Sie in [Über FastAPI-Versionen](versions.md){.internal-link target=_blank} gelesen haben, um die Versionsbereiche festzulegen.

Ihre `requirements.txt` könnte beispielsweise so aussehen:

```

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object" class="external-link" target="_blank">`Parameter Object` (в специфікації)</a> використовується FastAPI для:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

* *路径*可以包含 <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#key-expression" class="external-link" target="_blank">OpenAPI 3 表达式</a>（详见下文），可以使用带参数的变量，以及发送至您的 API 的原始请求的部分

### 回调路径表达式

回调*路径*支持包含发送给您的 API 的原始请求的部分的  <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#key-expression" class="external-link" target="_blank">OpenAPI 3 表达式</a>。
