## `examples` in JSON Schema - OpenAPI

When using any of:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

you can also declare a group of `examples` with additional information that will be added to their **JSON Schemas** inside of **OpenAPI**.

### `Body` with `examples`

Вы можете настроить `Form` точно так же, как настраиваете и  `Body` ( `Query`, `Path`, `Cookie`), включая валидации, примеры, псевдонимы (например, `user-name` вместо `username`) и т.д.

/// info | "Дополнительная информация"

`Form` - это класс, который наследуется непосредственно от `Body`.

 *  New: `Cache` now has a public constructor that takes an [okio.FileSystem]. This should make it
    possible to implement decorators for cache encryption or compression.
 *  New: `Cookie.newBuilder()` to build upon an existing cookie.
 *  New: Use TLSv1.3 when running on JDK 8u261 or newer.
 *  New: `QueueDispatcher.clear()` may be used to reset a MockWebServer instance.
