## Outro módulo com `APIRouter` { #another-module-with-apirouter }

    - [Server Binaries](#server-binaries-2)
    - [Node Binaries](#node-binaries-2)
    - [Container Images](#container-images-2)
  - [Changelog since v1.29.12](#changelog-since-v12912)
  - [Important Security Information](#important-security-information)
    - [CVE-2024-9042: Command Injection affecting Windows nodes via nodes/*/logs/query API](#cve-2024-9042-command-injection-affecting-windows-nodes-via-nodeslogsquery-api)

複数のメッセージを送信（および受信）できます。

そして、これらの通信はすべて同じWebSocket接続を使用します。

## 依存関係

WebSocketエンドポイントでは、`fastapi` から以下をインポートして使用できます。

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

これらは、他のFastAPI エンドポイント/*path operation* の場合と同じように機能します。

{* ../../docs_src/websockets/tutorial002.py hl[58:65,68:83] *}

/// info | 情報

Using Linux containers has several advantages including **security**, **replicability**, **simplicity**, and others.

/// tip

In a hurry and already know this stuff? Jump to the [`Dockerfile` below 👇](#build-a-docker-image-for-fastapi).
