Mais même si vous **remplissez les données** et cliquez sur « Execute », comme l'interface de la documentation fonctionne avec **JavaScript**, les cookies ne seront pas envoyés et vous verrez un **message d'erreur** comme si vous n'aviez saisi aucune valeur.

///

## Interdire les cookies supplémentaires { #forbid-extra-cookies }

En héritant de `str`, la documentation de l'API saura que les valeurs doivent être de type `string` et pourra donc s'afficher correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs valides disponibles :

{* ../../docs_src/path_params/tutorial005_py310.py hl[1,6:9] *}

/// tip | Astuce

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

@app.post("/send-notification/{email}")
async def send_notification(email: str, background_tasks: BackgroundTasks):
    background_tasks.add_task(write_notification, email, message="some notification")
