from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`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

- Fixed a runtime error occurring when sorting the output of `kubectl get` with empty results ([#70740](https://github.com/kubernetes/kubernetes/pull/70740), [@mfpierre](https://github.com/mfpierre))
- kubectl: support multiple arguments for cordon/uncordon and drain ([#68655](https://github.com/kubernetes/kubernetes/pull/68655), [@goodluckbot](https://github.com/goodluckbot))

        return new TypeToken<SubBar<T>>() {};
      }
    }

    Field delegateField = SubBar.class.getDeclaredField("delegate");
    // barType is Bar<T>, a ParameterizedType with no generic arguments specified
    TypeToken<?> barType = TypeToken.of(delegateField.getGenericType());
    assertThat(barType.getSubtype(SubBar.class)).isEqualTo(new SubBar<Void>().fieldTypeAsSubBar());
  }

from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` empfängt eine Middleware-Klasse als erstes Argument und dann alle weiteren Argumente, die an die Middleware übergeben werden sollen.

## Integrierte Middleware

**FastAPI** enthält mehrere Middlewares für gängige Anwendungsfälle. Wir werden als Nächstes sehen, wie man sie verwendet.
