## 检查用户名

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 <a href="https://docs.python.org/3/library/secrets.html" class="external-link" target="_blank">`secrets`</a> 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` 。

したがって、以下の行:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

は実行されません。

## デバッガーでコードを実行

コードから直接Uvicornサーバーを実行しているため、デバッガーから直接Pythonプログラム (FastAPIアプリケーション) を呼び出せます。

## Casos de Uso

Alguns casos de uso incluem:

* Converter requisições não-JSON para JSON (por exemplo, <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Descomprimir corpos de requisição comprimidos com gzip.
* Registrar automaticamente todos os corpos de requisição.
