This document focuses on showing a working example on how to use Object Lambda with MinIO, you must have [MinIO deployed in your environment](https://docs.min.io/community/minio-object-store/operations/installation.html) before you can start using external lambda functions. You also must install Python version 3.8 or later for the lambda handlers to work.

## Example Lambda handler

Install the necessary dependencies.
```sh

FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.

## Disable Syntax Highlighting { #disable-syntax-highlighting }

For example, you could disable syntax highlighting in Swagger UI.

Without changing the settings, syntax highlighting is enabled by default:

<img src="/img/tutorial/extending-openapi/image02.png">

    ;

    open fun encode(codePoint: Int): String = throw UnsupportedOperationException()
  }

  enum class Component {
    USER {
      override fun urlString(value: String): String = "http://$value@example.com/"

      override fun encodedValue(url: HttpUrl): String = url.encodedUsername

      override operator fun set(
        builder: HttpUrl.Builder,
        value: String,
      ) {

Para eso, puedes usar `WSGIMiddleware` y usarlo para envolver tu aplicación WSGI, por ejemplo, Flask, Django, etc.

## Usando `WSGIMiddleware`

Necesitas importar `WSGIMiddleware`.

Luego envuelve la aplicación WSGI (p. ej., Flask) con el middleware.

Y luego móntala bajo un path.

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

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

///

## Importar `File` y `Form`

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

## Definir parámetros `File` y `Form`

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

/// info

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure { #an-example-file-structure }

Let's say you have a file structure like this:

```
