Tornando al precedente esempio, **FastAPI**:

* Validerà che esiste un `item_id` nel percorso delle richieste `GET` e `PUT`.
* Validerà che `item_id` sia di tipo `int` per le richieste `GET` e `PUT`.
    * Se non lo è, il client vedrà un errore chiaro e utile.
* Controllerà se ci sia un parametro opzionale chiamato `q` (per esempio `http://127.0.0.1:8000/items/foo?q=somequery`) per le richieste `GET`.

* Überprüfen, dass es eine `item_id` im Pfad für `GET`- und `PUT`-Anfragen gibt.
* Überprüfen, ob die `item_id` vom Typ `int` für `GET`- und `PUT`-Anfragen ist.
    * Falls nicht, wird dem Client ein nützlicher, eindeutiger Fehler angezeigt.
* Prüfen, ob es einen optionalen Abfrageparameter namens `q` (wie in `http://127.0.0.1:8000/items/foo?q=somequery`) für `GET`-Anfragen gibt.

테스트해보기:

* 여러 브라우저 탭에서 앱을 엽니다.
* 각 탭에서 메시지를 작성합니다.
* 한 탭을 닫아보세요.

`WebSocketDisconnect` 예외가 발생하며, 다른 모든 클라이언트가 다음과 같은 메시지를 수신합니다:

```
Client #1596980209979 left the chat
```

/// tip | 팁

위 응용 프로그램은 여러 WebSocket 연결에 메시지를 브로드캐스트하는 방법을 보여주는 간단한 예제입니다.

그러나 모든 것을 메모리의 단일 리스트로 처리하므로, 프로세스가 실행 중인 동안만 동작하며 단일 프로세스에서만 작동합니다.
