from unicorn import UnicornMiddleware

app = FastAPI()

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

`app.add_middleware()` receives a middleware class as the first argument and any additional arguments to be passed to the middleware.

## Integrated middlewares

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

*   Extends `tf.keras.layers.Lambda` layers to support multi-argument lambdas,
    and keyword arguments when calling the layer.
*   Functional models now get constructed if *any* tensor in a layer call's
    arguments/keyword arguments comes from a keras input. Previously the
    functional api would only work if all of the elements in the first argument
    to the layer came from a keras input.

Mais si vous décidez d'apprendre à les utiliser, sachez qu'ensuite vous pouvez les utiliser directement dans **FastAPI**.

## Valeurs par défaut

De la même façon que vous pouvez passer `None` comme premier argument pour l'utiliser comme valeur par défaut, vous pouvez passer d'autres valeurs.

Disons que vous déclarez le paramètre `q` comme ayant une longueur minimale de `3`, et une valeur par défaut étant `"fixedquery"` :
