在浏览器中打开 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>。

在页面中，您可以设置：

* "Item ID"，用于路径。
* "Token"，作为查询参数。

/// tip

注意，查询参数 `token` 将由依赖项处理。

通过这样，您可以连接 WebSocket，然后发送和接收消息：

## 处理断开连接和多个客户端

  - A `create` or `update` API request with duplicate items in a keyed list no longer wipes out managedFields. Examples include env var entries with the same name, or port entries with the same containerPort in a pod spec.

クライアントが設定できる項目は以下の通りです。

* パスで使用される「Item ID」
* クエリパラメータとして使用される「Token」

/// tip | "豆知識"

クエリ `token` は依存パッケージによって処理されることに注意してください。

これにより、WebSocketに接続してメッセージを送受信できます。
