# Security Tools

When you need to declare dependencies with OAuth2 scopes you use `Security()`.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

 * The interface has no instance methods, so the tests focus on
 * value correctness and array integrity.  A tiny Mockito example
 * demonstrates that the interface can be mocked if another class
 * depends on it.

    itself. The idea is:

    - If users want only ListenableFuture, they depend on listenablefuture-1.0.

    - If users want all of Guava, they depend on guava, which, as of Guava
    27.0, depends on
    listenablefuture-9999.0-empty-to-avoid-conflict-with-guava. The 9999.0-...
    version number is enough for some build systems (notably, Gradle) to select

여러 메시지를 전송(그리고 수신)할 수 있습니다:

모든 메시지는 동일한 WebSocket 연결을 사용합니다.

## `Depends` 및 기타 사용하기

WebSocket 엔드포인트에서 `fastapi`에서 다음을 가져와 사용할 수 있습니다:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

이들은 다른 FastAPI 엔드포인트/*경로 작동*과 동일하게 동작합니다:

It could be called as:

```Python
oauth2_scheme(some, parameters)
```

So, it can be used with `Depends`.

### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.
