    suffix database.
 *  Fix: Use relative resource path when loading the public suffix database.
    Loading the resource using a path relative to the class prevents conflicts
    when the OkHttp classes are relocated (shaded) by allowing multiple private
    copies of the database.
 *  Fix: Accept cookies for URLs that have an IPv6 address for a host.

Quay trở lại ví dụ trước, **FastAPI** sẽ thực hiện:

    * Converte i tipi di Python (`str`, `int`, `float`, `bool`, `list`, ecc).
    * Oggetti `datetime`.
    * Oggetti `UUID`.
    * Modelli del database.
    * ...e molto di più.
* Generazione di una documentazione dell'API interattiva, con scelta dell'interfaccia grafica:
    * Swagger UI.
    * ReDoc.
