## Создать зависимость `get_current_user` { #create-a-get-current-user-dependency }

Давайте создадим зависимость `get_current_user`.

Помните, что у зависимостей могут быть подзависимости?

`get_current_user` будет иметь зависимость от того же `oauth2_scheme`, который мы создали ранее.

## Abhängigkeitsfehler und -Rückgabewerte { #dependencies-errors-and-return-values }

Sie können dieselben Abhängigkeits-*Funktionen* verwenden, die Sie normalerweise verwenden.

### Abhängigkeitsanforderungen { #dependency-requirements }

Sie können Anforderungen für einen <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> (wie Header) oder andere Unterabhängigkeiten deklarieren:

@Documented

  /**
   * Describes why the annotated element is incompatible with GWT. Since this is generally due to a

   *

 * It is identified by a unique combination of a group ID, artifact ID, version, classifier,
