### Аргумент "example" в UI документации

С любым из вышеуказанных методов это будет выглядеть так в `/docs`:

<img src="/img/tutorial/body-fields/image01.png">

### `Body` с аргументом `examples`

そのため、OpenAPIでは同じ目的のために<a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#fixed-fields-20" class="external-link" target="_blank">`example`</a>を独自に定義しており（`examples`ではなく`example`として）、それがdocs UI（Swagger UIを使用）で使用されています。

つまり、`example`はJSON Schemaの一部ではありませんが、OpenAPIの一部であり、それがdocs UIで使用されることになります。

### Example Tools to Run at Startup

Some examples of the tools that can do this job are:

* Docker
* Kubernetes
* Docker Compose
* Docker in Swarm Mode
* Systemd
* Supervisor
* Handled internally by a cloud provider as part of their services
* Others...

I'll give you more concrete examples in the next chapters.

## Restarts

Portanto, embora `example` não seja parte do JSON Schema, é parte da versão customizada do JSON Schema usada pelo OpenAPI, e é isso que vai ser usado dentro da UI de documentação.

Now you can use Trio internally in your app. Or even better, you can use AnyIO, to keep your code compatible with both Trio and asyncio. 🎉

## Deployment Concepts

These examples run the server program (e.g Uvicorn), starting **a single process**, listening on all the IPs (`0.0.0.0`) on a predefined port (e.g. `80`).

### Using the `openapi_examples` Parameter

You can declare the OpenAPI-specific `examples` in FastAPI with the parameter `openapi_examples` for:

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

The keys of the `dict` identify each example, and each value is another `dict`.

Each specific example `dict` in the `examples` can contain:

### OpenAPI-spezifische `examples`

Schon bevor **JSON Schema** `examples` unterstützte, unterstützte OpenAPI ein anderes Feld, das auch `examples` genannt wurde.

Diese **OpenAPI-spezifischen** `examples` finden sich in einem anderen Abschnitt der OpenAPI-Spezifikation. Sie sind **Details für jede *Pfadoperation***, nicht für jedes JSON-Schema.
