## バリデーションの追加

`q`はオプショナルですが、もし値が渡されてきた場合には、**50文字を超えないこと**を強制してみましょう。

### `Query`のインポート

そのために、まずは`fastapi`から`Query`をインポートします:

```Python hl_lines="3"
{!../../docs_src/query_params_str_validations/tutorial002.py!}
```

## デフォルト値として`Query`を使用

パラメータのデフォルト値として使用し、パラメータ`max_length`を50に設定します:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial002.py!}

024E          ; mapped                 ; 024F          # 5.0  LATIN CAPITAL LETTER Y WITH STROKE
