**Technology Stack:**
- Java 21+, Maven

## Architecture

### Package Structure

```

    /**
     * Default constructor.
     */
    public SearchBody() {
        super();
    }

    /** Search term for key matching */
    public String term;

    /** Query pattern for key matching */
    public String query;

</div>

Abre tu navegador en [http://127.0.0.1:8000](http://127.0.0.1:8000).

Ahí puedes establecer:

* El "ID del Ítem", usado en el path.
* El "Token" usado como un parámetro query.

/// tip | Consejo

Nota que el query `token` será manejado por una dependencia.

///

Con eso puedes conectar el WebSocket y luego enviar y recibir mensajes:

Bu parametreler, dependency'yi "çözmek" için **FastAPI**'nin kullanacağı şeylerdir.

Her iki durumda da şunlar olacak:

* `str` olan opsiyonel bir `q` query parametresi.
* Default değeri `0` olan `int` tipinde bir `skip` query parametresi.
* Default değeri `100` olan `int` tipinde bir `limit` query parametresi.

Her iki durumda da veriler dönüştürülecek, doğrulanacak, OpenAPI şemasında dokümante edilecek, vb.
