### Dependencies { #dependencies }

The same applies for [dependencies](tutorial/dependencies/index.md). If a dependency is a standard `def` function instead of `async def`, it is run in the external threadpool.

### Sub-dependencies { #sub-dependencies }

## 간단한 HTTP Basic Auth { #simple-http-basic-auth }

* `HTTPBasic`과 `HTTPBasicCredentials`를 임포트합니다.
* `HTTPBasic`을 사용해 "`security` scheme"을 생성합니다.
* *경로 처리*에서 dependency로 해당 `security`를 사용합니다.
* `HTTPBasicCredentials` 타입의 객체를 반환합니다:
    * 전송된 `username`과 `password`를 포함합니다.

/**
 * A request to collect the transitive dependencies and to build a dependency graph from them. There are three ways to
 * create a dependency graph. First, only the root dependency can be given. Second, a root dependency and direct
 * dependencies can be specified in which case the specified direct dependencies are merged with the direct dependencies

Nous les mettons donc dans leur propre module `dependencies` (`app/dependencies.py`).

Nous allons maintenant utiliser une dépendance simple pour lire un en-tête personnalisé `X-Token` :

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Astuce

Nous utilisons un en-tête inventé pour simplifier cet exemple.

Create a utility function to generate a new access token.

{* ../../docs_src/security/tutorial004_an_py310.py hl[4,7,13:15,29:31,82:90] *}

## Update the dependencies { #update-the-dependencies }

Update `get_current_user` to receive the same token as before, but this time, using JWT tokens.

Decode the received token, verify it, and return the current user.

* Все они будут включать предопределённые `responses`.
* Все эти *операции пути* будут иметь список `dependencies`, вычисляемых/выполняемых перед ними.
    * Если вы также объявите зависимости в конкретной *операции пути*, **они тоже будут выполнены**.
    * Сначала выполняются зависимости маршрутизатора, затем [`dependencies` в декораторе](dependencies/dependencies-in-path-operation-decorators.md), и затем обычные параметрические зависимости.
