Si vous ne voulez pas leur donner de valeur par défaut mais juste les rendre optionnels, utilisez `None` comme valeur par défaut.

Mais si vous voulez rendre un paramètre de requête obligatoire, vous pouvez juste ne pas y affecter de valeur par défaut :

{* ../../docs_src/query_params/tutorial005.py hl[6:7] *}

The keys "exp", "parent" and "sub" in the `claims` object are reserved and if present are ignored by MinIO.

If the token is not valid or access is not approved, the plugin must return a `403` (forbidden) HTTP status code. The body must have an `application/json` content-type with the following structure:

```json
{
    "reason": <string>
}
```

The reason message is returned to the client.
