## Crea `main.py`

Copia el ejemplo en un archivo `main.py`:

/// info

This requires installing `orjson` for example with `pip install orjson`.

### `UJSONResponse` { #ujsonresponse }

An alternative JSON response using <a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>.

/// info

This requires installing `ujson` for example with `pip install ujson`.

# Form Data

Cuando necesitas recibir campos de formulario en lugar de JSON, puedes usar `Form`.

/// info | Información

Para usar forms, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart

# Form Data { #form-data }

When you need to receive form fields instead of JSON, you can use `Form`.

/// info

To use forms, first install <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install python-multipart
```

/**
 * Trans2 QueryPathInformation request message for querying file metadata.
 * This class implements the TRANS2_QUERY_PATH_INFORMATION transaction to retrieve
 * various file information levels such as basic info, standard info, and attributes.

public class Trans2QueryPathInformation extends SmbComTransaction {

    private final int informationLevel;

    /**
     * Constructs a Trans2QueryPathInformation request.

Podrías usar la misma técnica para extender el JSON Schema y añadir tu propia información extra personalizada.

Por ejemplo, podrías usarlo para añadir metadatos para una interfaz de usuario frontend, etc.
