In diesem Beispiel haben wir kein Pydantic-Modell deklariert. Tatsächlich wird der Requestbody nicht einmal als JSON <abbr title="von einem einfachen Format, wie Bytes, in Python-Objekte konvertieren">geparst</abbr>, sondern direkt als `bytes` gelesen und die Funktion `magic_data_reader ()` wäre dafür verantwortlich, ihn in irgendeiner Weise zu parsen.

Dennoch können wir das zu erwartende Schema für den Requestbody deklarieren.

`secrets.compare_digest()` 需要仅包含 ASCII 字符（英语字符）的 `bytes` 或 `str`，这意味着它不适用于像`á`一样的字符，如 `Sebastián`。

为了解决这个问题，我们首先将 `username` 和 `password` 转换为使用 UTF-8 编码的 `bytes` 。

然后我们可以使用 `secrets.compare_digest()` 来确保 `credentials.username` 是 `"stanleyjobson"`，且 `credentials.password` 是`"swordfish"`。
