Pero si necesitas acceder a variables y objetos de la misma app de **FastAPI**, o necesitas realizar pequeñas tareas en segundo plano (como enviar una notificación por email), simplemente puedes usar `BackgroundTasks`.

E também depois que a `response` é gerada, antes de retorná-la.

Por exemplo, você pode adicionar um cabeçalho personalizado `X-Process-Time` contendo o tempo em segundos que levou para processar a solicitação e gerar uma resposta:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}

## Outros middlewares

 * <p>
 * Model transformers allow plugins and extensions to modify the POM model during the build process.
 * Transformations can be applied at three different stages:
 * <ol>
 *   <li>File model - The raw model as read directly from the file</li>
 *   <li>Raw model - The model after inheritance has been applied</li>
 *   <li>Effective model - The fully processed model with all interpolation and inheritance applied</li>
 * </ol>
