`app.add_middleware()` recebe uma classe de middleware como o primeiro argumento e quaisquer argumentos adicionais a serem passados para o middleware.

## Middlewares Integrados

**FastAPI** inclui vários middlewares para casos de uso comuns, veremos a seguir como usá-los.

/// note | Detalhes Técnicos

Para o próximo exemplo, você também poderia usar `from starlette.middleware.something import SomethingMiddleware`.
