If <code>D</code> returns normally, without starting a new
<code>panic</code>, the panicking sequence stops. In that case,
the state of functions called between <code>G</code> and the call to <code>panic</code>
is discarded, and normal execution resumes.
Any functions deferred by <code>G</code> before <code>D</code> are then run and <code>G</code>'s

          this.count = newCount; // write-volatile
          return true;

      return false;

    * This allows adding extra code after a dependency is done. It can be used, for example, to close database connections.
    * Dependencies with `yield` can be normal or `async`, **FastAPI** will run normal dependencies in a threadpool.
    * They can be combined with normal dependencies.
    * It's possible to have arbitrary trees/levels of dependencies with `yield` and exit steps are handled in the correct order automatically.

### Misc

- Fixed: during the kube-controller-manager restart, when the corresponding Endpoints resource was manually deleted and recreated, causing the endpointslice to fail to be created normally.

## Die normale **FastAPI**-Anwendung { #the-normal-fastapi-app }

Sehen wir uns zunächst an, wie die normale API-Anwendung aussehen würde, bevor wir den Callback hinzufügen.

Sie verfügt über eine *Pfadoperation*, die einen `Invoice`-Body empfängt, und einen Query-Parameter `callback_url`, der die URL für den Callback enthält.

# OpenAPI erweitern { #extending-openapi }

Es gibt einige Fälle, in denen Sie das generierte OpenAPI-Schema ändern müssen.

In diesem Abschnitt erfahren Sie, wie.

## Der normale Vorgang { #the-normal-process }

Der normale (Standard-)Prozess ist wie folgt.

Eine `FastAPI`-Anwendung (Instanz) verfügt über eine `.openapi()`-Methode, von der erwartet wird, dass sie das OpenAPI-Schema zurückgibt.

### Andere Hilfsfunktionen { #other-utility-functions }

Bu dependency'ler, normal dependency'lerde olduğu gibi `raise` ile exception fırlatabilir:

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[10,15] *}

### Return Değerleri { #return-values }

Ayrıca değer döndürebilirler ya da döndürmeyebilirler; dönen değer kullanılmayacaktır.

Ces dépendances peuvent `raise` des exceptions, comme des dépendances normales :

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[10,15] *}

### Gérer les valeurs de retour { #return-values }

Elles peuvent retourner des valeurs ou non, ces valeurs ne seront pas utilisées.
