In der Produktion hätten Sie eine der oben genannten Optionen.

Aber es ist die einfachste Möglichkeit, sich auf die Serverseite von WebSockets zu konzentrieren und ein funktionierendes Beispiel zu haben:

```Python hl_lines="2  6-38  41-43"
{!../../../docs_src/websockets/tutorial001.py!}
```

## Einen `websocket` erstellen

Erstellen Sie in Ihrer **FastAPI**-Anwendung einen `websocket`:

```Python hl_lines="1  46-47"

       *
       * A note on exception types:
       *
       * Android API level 10 throws ExceptionInInitializerError the first time and
       * ClassNotFoundException thereafter.
       *
       * Android API level 26 and JVM8 both let our Error propagate directly the first time and
       * throw NoClassDefFoundError thereafter. This is the proper behavior according to the spec.

### `Body` com `example`

Aqui nós passamos um `example` dos dados esperados por `Body()`:

```Python hl_lines="21-26"
{!../../../docs_src/schema_extra_example/tutorial003.py!}
```

### Exemplo na UI da documentação

Com qualquer um dos métodos acima, os `/docs` vão ficar assim:

<img src="/img/tutorial/body-fields/image01.png">

       *
       * A note on exception types:
       *
       * Android API level 10 throws ExceptionInInitializerError the first time and
       * ClassNotFoundException thereafter.
       *
       * Android API level 26 and JVM8 both let our Error propagate directly the first time and
       * throw NoClassDefFoundError thereafter. This is the proper behavior according to the spec.

In production you would have one of the options above.

But it's the simplest way to focus on the server-side of WebSockets and have a working example:

```Python hl_lines="2  6-38  41-43"
{!../../../docs_src/websockets/tutorial001.py!}
```

## Create a `websocket`

In your **FastAPI** application, create a `websocket`:

```Python hl_lines="1  46-47"

  protected String getKeyNotInPopulatedMap() throws UnsupportedOperationException {
    return "z";
  }

  @Override
  protected String getValueNotInPopulatedMap() throws UnsupportedOperationException {
    return "26";
  }

  /** Helper assertion comparing two maps */
  private void assertMapsEqual(Map<?, ?> expected, Map<?, ?> map) {
    assertEquals(expected, map);
    assertEquals(expected.hashCode(), map.hashCode());

Et nous analysons directement ce contenu YAML, puis nous utilisons à nouveau le même modèle Pydantic pour valider le contenu YAML :

```Python hl_lines="26-33"
{!../../../docs_src/path_operation_advanced_configuration/tutorial007.py!}
```

!!! tip "Astuce"
    Ici, nous réutilisons le même modèle Pydantic.

 *  Fix: Configure the multiplatform artifact (`com.squareup.okhttp3:okhttp:3.x.x`) to depend on the
    JVM artifact (`com.squareup.okhttp3:okhttp-jvm:3.x.x`) for Maven builds. This should work-around
