*경로 작동 데코레이터*에서 `dependencies`를 사용하면 편집기/도구 오류를 피하며 실행되도록 할 수 있습니다.

또한 코드에서 사용되지 않는 매개변수를 보고 불필요하다고 생각할 수 있는 새로운 개발자의 혼란을 방지하는데 도움이 될 수 있습니다.

/// info | 정보

이 예시에서 `X-Key`와 `X-Token`이라는 커스텀 헤더를 만들어 사용했습니다.

그러나 실제로 보안을 구현할 때는 통합된 [보안 유틸리티 (다음 챕터)](../security/index.md){.internal-link target=_blank}를 사용하는 것이 더 많은 이점을 얻을 수 있습니다.

## 의존성 오류와 값 반환하기

평소에 사용하던대로 같은 의존성 *함수*를 사용할 수 있습니다.

  * Un parámetro de query.
  * Un header.
  * Una cookie.
* `http`: sistemas de autenticación HTTP estándar, incluyendo:
  * `bearer`: un header `Authorization` con un valor de `Bearer ` más un token. Esto se hereda de OAuth2.
  * Autenticación básica HTTP.
  * Digest HTTP, etc.
* `oauth2`: todas las formas de OAuth2 para manejar la seguridad (llamadas "flujos").

We see that we are going to need some dependencies used in several places of the application.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

    * Einem Query-Parameter.
    * Einem Header.
    * Einem Cookie.
* `http`: Standard-HTTP-Authentifizierungssysteme, einschließlich:
    * `bearer`: ein Header `Authorization` mit dem Wert `Bearer` plus einem Token. Dies wird von OAuth2 geerbt.
    * HTTP Basic Authentication.
    * HTTP Digest, usw.
* `oauth2`: Alle OAuth2-Methoden zum Umgang mit Sicherheit (genannt „Flows“).
