`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`.

  }

  /**
   * Creates a {@code HashCode} from a hexadecimal ({@code base 16}) encoded string. The string must
   * be at least 2 characters long, and contain only valid, lower-cased hexadecimal characters.
   *
   * <p>This method accepts the exact format generated by {@link #toString}. If you require more
   * lenient {@code base 16} decoding, please use {@link com.google.common.io.BaseEncoding#decode}

```Python hl_lines="11  14-16"
{!../../docs_src/sub_applications/tutorial001.py!}
```

### Mount the sub-application

In your top-level application, `app`, mount the sub-application, `subapi`.

In this case, it will be mounted at the path `/subapi`:

```Python hl_lines="11  19"
{!../../docs_src/sub_applications/tutorial001.py!}
```

### Check the automatic API docs

Now, run the `fastapi` command with your file:

     * else a dependency collection request will be done.
     *
     * @return the id of the path scope
     */
    String pathScope() default "";

    /**
     * The request type, in case the default one is not correct.
     * Valid values are {@code collect}, {@code flatten}, or {@code resolve}.
     *
     * @return the request type
     */
    String requestType() default "";
