/// tip

Here we use [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) instead of `time.time()` because it can be more precise for these use cases. 🤓

`status_code` 매개변수는 HTTP 상태 코드를 숫자로 입력받습니다.

/// info | 정보

`status_code` 는 파이썬의 [`http.HTTPStatus`](https://docs.python.org/3/library/http.html#http.HTTPStatus) 와 같은 `IntEnum` 을 입력받을 수도 있습니다.

`status_code` 매개변수는:

* 응답에서 해당 상태 코드를 반환합니다.
* 상태 코드를 OpenAPI 스키마(따라서, 사용자 인터페이스에도)에 문서화합니다:

## 检查用户名 { #check-the-username }

以下是更完整的示例。

使用依赖项检查用户名与密码是否正确。

为此要使用 Python 标准模块 [`secrets`](https://docs.python.org/3/library/secrets.html) 检查用户名与密码。

`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` 。

В OpenAPI це буде визначено як `anyOf`.

Для цього використайте стандартну підказку типу Python [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

/// tip | Astuce

Ici, nous utilisons [`time.perf_counter()`](https://docs.python.org/3/library/time.html#time.perf_counter) au lieu de `time.time()` car cela peut être plus précis pour ces cas d’usage. 🤓
