## 実行

/// info | 情報

まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`。

これは、**OAuth2**が `ユーザー名` や `パスワード` を送信するために、「フォームデータ」を使うからです。

例を実行します:

<div class="termy">

```console
$ uvicorn main:app --reload

Pydantic 支持使用外部库从这些类型的文件中读取。您可以在<a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support" class="external-link" target="_blank">Pydantic 设置: Dotenv (.env) 支持</a>中阅读更多相关信息。

/// tip

要使其工作，您需要执行 `pip install python-dotenv`。

### `.env` 文件

您可以使用以下内容创建一个名为 `.env` 的文件：

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### 从 `.env` 文件中读取设置
