Damit können Sie den WebSocket verbinden und dann Nachrichten senden und empfangen:

## Verbindungsabbrüche und mehrere Clients handhaben { #handling-disconnections-and-multiple-clients }

Wenn eine WebSocket-Verbindung geschlossen wird, löst `await websocket.receive_text()` eine `WebSocketDisconnect`-Exception aus, die Sie dann wie in folgendem Beispiel abfangen und behandeln können.

```
mc admin service restart myminio
```

### Using WebIdentiy API

Client ID can be found by clicking any of the clients listed [here](http://localhost:8080/auth/admin/master/console/#/realms/minio/clients). If you have followed the above steps docs, the default Client ID will be `account`.

```

// existing ETag entry.
//
// Due to legacy S3 clients, that make incorrect assumptions
// about HTTP headers, Set should be used instead of
// http.Header.Set(...). Otherwise, some S3 clients will not
// able to extract the ETag.
func Set(etag ETag, h http.Header) {
	// Some (broken) S3 clients expect the ETag header to
	// literally "ETag" - not "Etag". Further, some clients
	// expect an ETag in double quotes. Therefore, we set the

participant client as Client
participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation
participant tasks as Background tasks

    Note over client,operation: Can raise exceptions, including HTTPException
    client ->> dep: Start request
    Note over dep: Run code up to yield
    opt raise Exception

Nun erstellen wir ein `HeroCreate`-Modell, das die Daten der Clients **validiert**.

Es hat dieselben Felder wie `HeroBase`, und es hat auch `secret_name`.

Wenn die Clients **einen neuen Helden erstellen**, senden sie jetzt den `secret_name`, er wird in der Datenbank gespeichert, aber diese geheimen Namen werden den API-Clients nicht zurückgegeben.

                This is particularly useful when automatically generating clients or
                SDKs for your API.

                Read more about it in the
                [FastAPI docs about how to Generate Clients](https://fastapi.tiangolo.com/advanced/generate-clients/#custom-generate-unique-id-function).
                """
            ),

::: fastapi.websockets.WebSocketDisconnect

When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

Read more about it in the [FastAPI docs for WebSockets](https://fastapi.tiangolo.com/advanced/websockets/#handling-disconnections-and-multiple-clients)

::: fastapi.websockets.WebSocketState

Now we create a `HeroCreate` model, this is the one that will **validate** the data from the clients.

It has the same fields as `HeroBase`, and it also has `secret_name`.

Now, when the clients **create a new hero**, they will send the `secret_name`, it will be stored in the database, but those secret names won't be returned in the API to the clients.
