- 🚢 Инструкции по развёртыванию с использованием Docker Compose, включая настройку фронтенд‑прокси Traefik для автоматического получения сертификатов HTTPS.

également avoir ses propres sous‑applications montées et tout fonctionnera correctement, car FastAPI gère automatiquement tous ces `root_path`.

Vous en apprendrez davantage sur `root_path` et sur la façon de l'utiliser explicitement dans la section [Derrière un proxy](behind-a-proxy.md)....

Оскільки це WebSocket, не має сенсу піднімати `HTTPException`, натомість ми піднімаємо `WebSocketException`.

Ви можете використати код закриття з [чинних кодів, визначених у специфікації](https://tools.ietf.org/html/rfc6455#section-7.4.1).

/// note | Detalles Técnicos

Si tienes dependencias con `yield`, el código de salida se ejecutará *después* del middleware.

Si hubiera tareas en segundo plano (cubiertas en la sección [Tareas en segundo plano](background-tasks.md), lo verás más adelante), se ejecutarán *después* de todo el middleware.
