Si te comunicas con esa *path operation* enviando dos headers HTTP como:

```
X-Token: foo
X-Token: bar
```

El response sería como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulación { #recap }

 * <p>
 * This class is immutable and thread-safe, suitable for use in concurrent operations.
 *
 * @param <REQ> The type of the request
 * @param <REP> The type of the response, which must extend {@code Result<REQ>}
 * @param request The original request that was processed
 * @param result The result of the request, if successful; may be null if an error occurred

If you want to secure your API, there are several better things you can do, for example:

* Make sure you have well defined Pydantic models for your request bodies and responses.
* Configure any required permissions and roles using dependencies.
* Never store plaintext passwords, only password hashes.
* Implement and use well-known cryptographic tools, like pwdlib and JWT tokens, etc.

 *   <li>Building the query and filter query for the suggestion request.</li>
 *   <li>Processing the request and handling the response or failure.</li>
 *   <li>Creating the response from the search results.</li>
 * </ul>
 *
 * <p>Example usage:</p>
 * <pre>
 * SuggestRequest suggestRequest = new SuggestRequest();
 * suggestRequest.setIndex("my_index");

     * @throws SmbException if an error occurs during message creation
     */

Crea una variable `ALGORITHM` con el algoritmo usado para firmar el token JWT y configúralo a `"HS256"`.

Crea una variable para la expiración del token.

Define un Modelo de Pydantic que se usará en el endpoint de token para el response.

Crea una función de utilidad para generar un nuevo token de acceso.
