## `examples` im JSON-Schema – OpenAPI

Bei Verwendung von:

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

können Sie auch eine Gruppe von `examples` mit zusätzlichen Informationen deklarieren, die zu ihren **JSON-Schemas** innerhalb von **OpenAPI** hinzugefügt werden.

## Использование `example` и `examples` в OpenAPI

При использовании любой из этих функций:

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

вы также можете добавить аргумент, содержащий `example` или группу `examples` с дополнительной информацией, которая будет добавлена в **OpenAPI**.

    {!> ../../../docs_src/schema_extra_example/tutorial002.py!}
    ```

## `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**.
