## Çok Teknik Detaylar

!!! warning
    Muhtemelen burayı atlayabilirsiniz.

    Bunlar, **FastAPI**'nin altta nasıl çalıştığına dair çok teknik ayrıntılardır.

    Biraz teknik bilginiz varsa (co-routines, threads, blocking, vb)ve FastAPI'nin "async def" ile normal "def" arasındaki farkı nasıl işlediğini merak ediyorsanız, devam edin.

En utilisant seulement `BackgroundTasks` (et non `BackgroundTask`), il est possible de l'utiliser en tant que paramètre de *fonction de chemin* et de laisser **FastAPI** gérer le reste pour vous, comme en utilisant l'objet `Request` directement.

It will be clearly marked as deprecated in the interactive docs:

## Recap

    ```

=== "Python 3.8+"

    ```Python hl_lines="8  10"
    {!> ../../../docs_src/query_params/tutorial004.py!}
    ```

## Required query parameters

When you declare a default value for non-path parameters (for now, we have only seen query parameters), then it is not required.

If you don't want to add a specific value but just make it optional, set the default as `None`.
