FastAPI will use this return type to:

* **Validate** the returned data.
    * If the data is invalid (e.g. you are missing a field), it means that *your* app code is broken, not returning what it should, and it will return a server error instead of returning incorrect data. This way you and your clients can be certain that they will receive the data and the data shape expected.
* Add a **JSON Schema** for the response, in the OpenAPI *path operation*.

* **Validar** los datos devueltos.
    * Si los datos son inválidos (por ejemplo, falta un campo), significa que el código de *tu* aplicación está defectuoso, no devolviendo lo que debería, y retornará un error del servidor en lugar de devolver datos incorrectos. De esta manera, tú y tus clientes pueden estar seguros de que recibirán los datos y la forma de los datos esperada.

但在我們的程式碼中實際使用的是 `secrets.compare_digest()`。

簡而言之，將 `stanleyjobsox` 與 `stanleyjobson` 比較所花的時間，會與將 `johndoe` 與 `stanleyjobson` 比較所花的時間相同；密碼也一樣。

如此一來，在應用程式程式碼中使用 `secrets.compare_digest()`，就能安全地防禦這整類的安全攻擊。

limits the impact of these use-after-free bugs by preventing reuse of freed
memory regions until the garbage collector is able to determine that it is
safe. Typically, a use-after-free bug will result in a fault and a helpful
error message, but this package reserves the right to not force a fault on
freed memory. That means a valid implementation of this package is to just
allocate all memory the way the runtime normally would, and in fact, it
