doSend0( req );
                            } while( req.hasMoreElements() && req.nextElement() != null );

                            /* 
                             * Receive multiple fragments
                             */

                            long timeout = RESPONSE_TIMEOUT;
                            resp.expiration = System.currentTimeMillis() + timeout;

Durch die Berücksichtigung dieser Konzepte können Sie die beste Variante der Bereitstellung **Ihrer eigenen APIs** **evaluieren und konzipieren**.

In den nächsten Kapiteln werde ich Ihnen mehr **konkrete Rezepte** für die Bereitstellung von FastAPI-Anwendungen geben.

Aber schauen wir uns zunächst einmal diese grundlegenden **konzeptionellen Ideen** an. Diese Konzepte gelten auch für jede andere Art von Web-API. 💡

## Sicherheit – HTTPS

    * verifica che la richiesta abbia un attributo obbligatorio `price` e che sia di tipo `float`.
    * verifica che la richiesta abbia un attributo opzionale `is_offer` e che sia di tipo `bool`, se presente.
    * Tutto questo funzionerebbe anche con oggetti JSON più complessi.
* Convertirà *da* e *a* JSON automaticamente.
* Documenterà tutto con OpenAPI, che può essere usato per:
    * Sistemi di documentazione interattivi.

   * regular output/input of Photoshop (which can also export to various image formats; note that
   * files with extension "PSB" are in a distinct but related format).
   *
   * <p>This is a more recent replacement for the older, experimental type {@code x-photoshop}: <a
   * href="http://tools.ietf.org/html/rfc2046#section-6">RFC-2046.6</a>.
   *
   * @since 15.0

Als je een recentere versie van Python kunt kiezen voor je project, kun je profiteren van die extra eenvoud.

In alle documentatie staan voorbeelden die compatibel zijn met elke versie van Python (als er een verschil is).

    * Revisar si tiene un atributo requerido `price` que debe ser un `float`.
    * Revisar si tiene un atributo opcional `is_offer`, que debe ser un `bool`si está presente.
    * Todo esto funcionaría para objetos JSON profundamente anidados.
* Convertir de y a JSON automáticamente.
* Documentar todo con OpenAPI que puede ser usado por:
    * Sistemas de documentación interactiva.

Those worker processes would be the ones running your application, they would perform the main computations to receive a **request** and return a **response**, and they would load anything you put in variables in RAM.
