# Handbuch für fortgeschrittene Benutzer { #advanced-user-guide }

## Zusatzfunktionen { #additional-features }

Das Haupt-[Tutorial – Benutzerhandbuch](../tutorial/index.md) sollte ausreichen, um Ihnen einen Überblick über alle Hauptfunktionen von **FastAPI** zu geben.

In den nächsten Abschnitten sehen Sie weitere Optionen, Konfigurationen und zusätzliche Funktionen.

/// tip | Tipp

Die nächsten Abschnitte sind **nicht unbedingt „fortgeschritten“**.

            roleQueryHelper.addCookieNameMapping("admin", "administrator");

            Cookie adminCookie = new Cookie("admin", "true");

## Recursos Adicionais { #additional-features }

O [Tutorial - Guia de Usuário](../tutorial/index.md) principal deve ser o suficiente para dar a você um tour por todos os principais recursos do **FastAPI**.

Nas próximas seções você verá outras opções, configurações, e recursos adicionais.

As próximas seções **não são necessariamente "avançadas"**.

```mermaid

common_parameters(["common_parameters"])
read_items["/items/"]
read_users["/users/"]

common_parameters --> read_items
common_parameters --> read_users
```

De esta manera escribes código compartido una vez y **FastAPI** se encarga de llamarlo para tus *path operations*.

Et si vous sélectionnez le scope `me` mais pas le scope `items`, vous pourrez accéder à `/users/me/` mais pas à `/users/me/items/`.

    when you call `contains(null)` on them!
 *  Fix: Retain binary-compatibility in `okhttp3.internal.HttpHeaders.hasBody()`. Some unscrupulous
    coders call this and we don't want their users to suffer.
