Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI { #adding-asgi-middlewares }

Como o **FastAPI** é baseado no Starlette e implementa a especificação <abbr title="Asynchronous Server Gateway Interface – Interface de Gateway de Servidor Assíncrona">ASGI</abbr>, você pode usar qualquer middleware ASGI.

O middleware não precisa ser feito para o FastAPI ou Starlette para funcionar, desde que siga a especificação ASGI.
