FastApi - Code Search

docs/es/docs/async.md

Si estás trabajando con **FastAPI** no tienes que preocuparte por eso, porque esa "primera" función será tu *path operation function*, y FastAPI sabrá cómo hacer lo correcto.

Pero si deseas usar `async` / `await` sin FastAPI, también puedes hacerlo.

* Um `client_secret` opcional (não precisamos dele em nosso exemplo).

/// info | Informação

O `OAuth2PasswordRequestForm` não é uma classe especial para **FastAPI** como é `OAuth2PasswordBearer`.

`OAuth2PasswordBearer` faz com que **FastAPI** saiba que é um esquema de segurança. Portanto, é adicionado dessa forma ao OpenAPI.

# Шаблоны { #templates }

Вы можете использовать любой шаблонизатор вместе с **FastAPI**.

Часто выбирают Jinja2 — тот же, что используется во Flask и других инструментах.

Есть утилиты для простой настройки, которые вы можете использовать прямо в своем приложении **FastAPI** (предоставляются Starlette).

こうすることで、**複数の場所**で**そのPydanticモデルを再利用**でき、バリデーションやメタデータを、すべてのクエリパラメータに対して一度に宣言できます。😎

/// note | 備考

この機能は、FastAPIのバージョン `0.115.0` からサポートされています。🤓

///

## クエリパラメータにPydanticモデルを使用する

必要な**複数のクエリパラメータ**を**Pydanticモデル**で宣言し、さらに、それを `Query` として宣言しましょう:

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI**は、リクエストの**クエリパラメータ**からそれぞれの**フィールド**のデータを**抽出**し、定義された**Pydanticモデル**を提供します。
