画像は `FileResponse` を使って直接返す必要がある点に注意してください。

///

/// info | 情報

`responses` パラメータで明示的に別のメディアタイプを指定しない限り、FastAPI はレスポンスがメインのレスポンスクラスと同じメディアタイプ（デフォルトは `application/json`）であるとみなします。

ただし、メディアタイプが `None` のカスタムレスポンスクラスを指定している場合、モデルが関連付けられた追加レスポンスには FastAPI は `application/json` を使用します。

///

## 情報の結合 { #combining-information }

`response_model`、`status_code`、`responses` パラメータなど、複数の場所からのレスポンス情報を組み合わせることもできます。

import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | 팁

[`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) 의 두 번째 인자는 반환할 기본값입니다.

제공하지 않으면 기본값은 `None`이며, 여기서는 사용할 기본값으로 `"World"`를 제공합니다.
