А затем — как работать с [CORS с помощью `CORSMiddleware`](../tutorial/cors.md){.internal-link target=_blank}.

В этом разделе посмотрим, как использовать другие middleware.

## Добавление ASGI middleware { #adding-asgi-middlewares }

Так как **FastAPI** основан на Starlette и реализует спецификацию <abbr title="Asynchronous Server Gateway Interface – Асинхронный шлюзовой интерфейс сервера">ASGI</abbr>, вы можете использовать любое ASGI middleware.

### Adding New Features

1. Read related source files and tests
2. Write implementation following existing patterns
3. Add comprehensive tests
4. Run `mvn formatter:format license:format test`

/**
 * A {@code SetMultimap} whose set of values for a given key are kept sorted; that is, they comprise
 * a {@link SortedSet}. It cannot hold duplicate key-value pairs; adding a key-value pair that's
 * already in the multimap has no effect. This interface does not specify the ordering of the
 * multimap's keys. See the {@link Multimap} documentation for information common to all multimaps.
 *

* Path `prefix`: `/items`.
* `tags`: (just one tag: `items`).
* Extra `responses`.
* `dependencies`: they all need that `X-Token` dependency we created.

So, instead of adding all that to each *path operation*, we can add it to the `APIRouter`.

API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
