Mais même si vous n'utilisez pas ou n'utiliserez jamais **FastAPI**, vous pourriez bénéficier d'apprendre quelques choses sur ces dernières.

/// note

Si vous êtes un expert Python, et que vous savez déjà **tout** sur les annotations de type, passez au chapitre suivant.

## Motivations

Prenons un exemple simple :

Não faz diferença. O **FastAPI** sabe o que fazer.

Caso você não conheça, veja em [Async: *"Com Pressa?"*](../../async.md#com-pressa){.internal-link target=_blank} a sessão acerca de `async` e `await` na documentação.

*path operations* のいずれにおいても、`response_model`パラメータを使用して、レスポンスのモデルを宣言することができます:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

/// note | 備考

`response_model`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数* のパラメータではありません。

   * LinkedHashMap because one target node may be mapped to both a predecessor and a successor. A

## `websocket` を作成する

**FastAPI** アプリケーションで、`websocket` を作成します。

/// note | 技術詳細

`from starlette.websockets import WebSocket` を使用しても構いません.

**FastAPI** は開発者の利便性のために、同じ `WebSocket` を提供します。しかし、こちらはStarletteから直接提供されるものです。
