`StaticFiles` を使用して、ディレクトリから静的ファイルを自動的に提供できます。

## `StaticFiles` の使用

* `StaticFiles` をインポート。
* `StaticFiles()` インスタンスを生成し、特定のパスに「マウント」。

```Python hl_lines="2  6"
{!../../docs_src/static_files/tutorial001.py!}
```

/// note | "技術詳細"

`from starlette.staticfiles import StaticFiles` も使用できます。

**FastAPI**は、開発者の利便性のために、`starlette.staticfiles` と同じ `fastapi.staticfiles` を提供します。しかし、実際にはStarletteから直接渡されています。

///

### 「マウント」とは

Para esses casos, você pode usar o `jsonable_encoder` para converter seus dados antes de repassá-los para a resposta:

```Python hl_lines="6-7  21-22"
{!../../docs_src/response_directly/tutorial001.py!}
```

/// note | Detalhes Técnicos

Você também pode utilizar `from starlette.responses import JSONResponse`.
