第一次打开 URL（或在 API 文档中点击 **Execute** 按钮）时，浏览器要求输入用户名与密码：

## 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`。

* Running on startup
* Restarts
* **Replication (the number of processes running)**
* Memory
* Previous steps before starting

Up to this point, with all the tutorials in the docs, you have probably been running a **server program**, for example, using the `fastapi` command, that runs Uvicorn, running a **single process**.

### Etkileşimli API Dokümantasyonu

Şimdi <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> bağlantısını açalım.

<a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank">Swagger UI</a> tarafından sağlanan otomatik etkileşimli bir API dokümantasyonu göreceğiz:

`myapp.py` 内の自動変数には、値が `"__main __"` の変数 `__name__` はありません。

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。
