### Dependency'lerle WebSockets'i Deneyin { #try-the-websockets-with-dependencies }

Uygulamanızı çalıştırın:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

### 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 }

    }

    private static String formatLocationInPom(Dependency dependency) {

    }

    public Dependency getDependency() {
        return dependency;
    }

그다음 사용자명과 비밀번호를 입력하면, 브라우저가 자동으로 해당 값을 헤더에 담아 전송합니다.

## 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

  dependencies:
    "@types/node" "*"

"@types/eslint-scope@^3.7.3":
  version "3.7.4"
  resolved "https://registry.yarnpkg.com/@types/eslint-scope/-/eslint-scope-3.7.4.tgz#37fc1223f0786c39627068a12e94d6e6fc61de16"

  dependencies:
    "@types/eslint" "*"
    "@types/estree" "*"

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.
