Beachten Sie, dass Sie keine spezielle Klasse erstellen und diese irgendwo an **FastAPI** übergeben müssen, um sie zu „registrieren“ oder so ähnlich.

Sie übergeben es einfach an `Depends` und **FastAPI** weiß, wie der Rest erledigt wird.

///

## `Annotated`-Abhängigkeiten wiederverwenden { #share-annotated-dependencies }

In den Beispielen oben sehen Sie, dass es ein kleines bisschen **Codeverdoppelung** gibt.

This also means that if you are inside a utility function that you are calling inside of your *path operation function*, and you raise the `HTTPException` from inside of that utility function, it won't run the rest of the code in the *path operation function*, it will terminate that request right away and send the HTTP error from the `HTTPException` to the client.

/// check

Notice that you don't have to create a special class and pass it somewhere to **FastAPI** to "register" it or anything similar.

You just pass it to `Depends` and **FastAPI** knows how to do the rest.

///

## Share `Annotated` dependencies { #share-annotated-dependencies }

In the examples above, you see that there's a tiny bit of **code duplication**.

Par exemple, si le **serveur d'application** ne reçoit des communications que du **proxy** de confiance, vous pouvez définir `--forwarded-allow-ips="*"` pour lui faire faire confiance à toutes les IP entrantes, puisqu'il ne recevra des requêtes que depuis l'IP utilisée par le **proxy**.
