## Importer `Query`

Pour cela, importez d'abord `Query` depuis `fastapi` :

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

## Utiliser `Query` comme valeur par défaut

Construisez ensuite la valeur par défaut de votre paramètre avec `Query`, en choisissant 50 comme `max_length` :

```Python hl_lines="9"

    ```Python hl_lines="11"
    {!> ../../../docs_src/query_params_str_validations/tutorial008_py310.py!}
    ```

## 📛 🔢

🌈 👈 👆 💚 🔢 `item-query`.

💖:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

✋️ `item-query` 🚫 ☑ 🐍 🔢 📛.

🔐 🔜 `item_query`.

✋️ 👆 💪 ⚫️ ⚫️❔ `item-query`...

⤴️ 👆 💪 📣 `alias`, & 👈 📛 ⚫️❔ 🔜 ⚙️ 🔎 🔢 💲:

### `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!}
```

    Aber **FastAPI** wird wissen, dass es zuerst `query_extractor` auflösen muss, um dessen Resultat `query_or_cookie_extractor` zu übergeben, wenn dieses aufgerufen wird.
