If you don't specify the `servers` parameter and `root_path` is equal to `/`, the `servers` property in the generated OpenAPI schema will be omitted entirely by default, which is the equivalent of a single server with a `url` value of `/`.

/// note | Технические детали

Свойство `servers` в спецификации OpenAPI является необязательным.

Если вы не укажете параметр `servers`, а `root_path` равен `/`, то свойство `servers` в сгенерированной схеме OpenAPI по умолчанию будет опущено. Это эквивалентно серверу со значением `url` равным `/`.

///

### Отключить автоматическое добавление сервера из `root_path` { #disable-automatic-server-from-root-path }

///

/// note | Detalles Técnicos

La propiedad `servers` en la especificación de OpenAPI es opcional.

Si no especificas el parámetro `servers` y `root_path` es igual a `/`, la propiedad `servers` en el esquema de OpenAPI generado se omitirá por completo por defecto, lo cual es equivalente a un único server con un valor `url` de `/`.

///

///

/// note | Technische Details

Die Eigenschaft `servers` in der OpenAPI-Spezifikation ist optional.

Wenn Sie den Parameter `servers` nicht angeben und `root_path` den Wert `/` hat, wird die Eigenschaft `servers` im generierten OpenAPI-Schema standardmäßig vollständig weggelassen, was dem Äquivalent eines einzelnen Servers mit einem `url`-Wert von `/` entspricht.
