## 同じ依存関係の複数回の使用 { #using-the-same-dependency-multiple-times }

依存関係の1つが同じ*path operation*に対して複数回宣言されている場合、例えば、複数の依存関係が共通のサブ依存関係を持っている場合、**FastAPI** はリクエストごとに1回だけそのサブ依存関係を呼び出します。

여러 메시지를 전송(그리고 수신)할 수 있습니다:

그리고 모든 메시지는 동일한 WebSocket 연결을 사용합니다.

## `Depends` 및 기타 사용하기 { #using-depends-and-others }

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

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

이들은 다른 FastAPI 엔드포인트/*경로 처리*와 동일하게 동작합니다:

你必須確保每個操作的 `operationId` 都是唯一的。

{* ../../docs_src/path_operation_advanced_configuration/tutorial001_py310.py hl[6] *}

### 使用路徑操作函式（path operation function）的名稱作為 operationId { #using-the-path-operation-function-name-as-the-operationid }

如果你想用 API 的函式名稱作為 `operationId`，你可以遍歷所有路徑，並使用各自的 `APIRoute.name` 覆寫每個*路徑操作*的 `operation_id`。

應在加入所有*路徑操作*之後再這麼做。
