Это даёт вам большую гибкость. Вы можете возвращать любые типы данных, переопределять любые объявления или валидацию данных и т.д.

## Использование `jsonable_encoder` в `Response` { #using-the-jsonable-encoder-in-a-response }

Поскольку **FastAPI** не изменяет объект `Response`, который вы возвращаете, вы должны убедиться, что его содержимое готово к отправке.

          message.startsWith("Negotiated ") -> Type.Handshake
          message.startsWith("Found resumable session") -> Type.Handshake
          message.startsWith("Resuming session") -> Type.Handshake
          message.startsWith("Using PSK to derive early secret") -> Type.Handshake
          else -> Type.Unknown
        }

    override fun toString(): String =
      if (param != null) {
        message + "\n" + param
      } else {

    // Assert they are all equal (using the transitive property)

Dadurch haben Sie viel Flexibilität. Sie können jeden Datentyp zurückgeben, jede Datendeklaration oder -validierung überschreiben, usw.

## Verwendung des `jsonable_encoder` in einer `Response` { #using-the-jsonable-encoder-in-a-response }

Da **FastAPI** keine Änderungen an einer von Ihnen zurückgegebenen `Response` vornimmt, müssen Sie sicherstellen, dass deren Inhalt dafür bereit ist.

Esto te da mucha flexibilidad. Puedes devolver cualquier tipo de datos, sobrescribir cualquier declaración o validación de datos, etc.

## Usar el `jsonable_encoder` en una `Response` { #using-the-jsonable-encoder-in-a-response }

Como **FastAPI** no realiza cambios en una `Response` que devuelves, tienes que asegurarte de que sus contenidos estén listos para ello.

## Usando `Jinja2Templates` { #using-jinja2templates }

* Importa `Jinja2Templates`.
* Crea un objeto `templates` que puedas reutilizar más tarde.
* Declara un parámetro `Request` en la *path operation* que devolverá una plantilla.

 * appropriate primitive specialization such as {@code IntPredicate}) instead whenever possible.
 * Otherwise, at least reduce <i>explicit</i> dependencies on this type by using lambda expressions
 * or method references instead of classes, leaving your code easier to migrate in the future.

 * <p>To use a reference of this type (say, named {@code guavaPredicate}) in a context where {@code
