So, let's review it from that simplified point of view:

* The user types the `username` and `password` in the frontend, and hits `Enter`.
* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).
* The API checks that `username` and `password`, and responds with a "token" (we haven't implemented any of this yet).

Voyons cela selon ce point de vue simplifié :

- L'utilisateur saisit le `username` et le `password` dans le frontend, puis appuie sur Entrée.
- Le frontend (exécuté dans le navigateur de l'utilisateur) envoie ce `username` et ce `password` vers une URL spécifique de notre API (déclarée avec `tokenUrl="token"`).
- L'API vérifie ce `username` et ce `password`, et répond avec un « token » (nous n'avons encore rien implémenté de tout cela).

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"`。

这类似于：

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):

Um dies zu lösen, konvertieren wir zunächst den `username` und das `password` in UTF-8-codierte `bytes`.

Dann können wir `secrets.compare_digest()` verwenden, um sicherzustellen, dass `credentials.username` `"stanleyjobson"` und `credentials.password` `"swordfish"` ist.

Dies wäre das gleiche wie:

```Python

    }
