# 設定と環境変数 { #settings-and-environment-variables }

多くの場合、アプリケーションは外部の設定や構成を必要とします。たとえば、シークレットキー、データベース認証情報、メールサービスの認証情報などです。

これらの設定の多くは可変（変更されうる）で、データベースのURLのようなものがあります。また、多くはシークレットのように機微な情報です。

そのため、アプリケーションが読み取る環境変数で提供するのが一般的です。

You can define files to be uploaded by the client using `File`.

/// info

To receive uploaded files, first install [`python-multipart`](https://github.com/Kludex/python-multipart).

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then install it, for example:

```console
$ pip install python-multipart
```

This is because uploaded files are sent as "form data".

We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.

## Our Standards

Examples of behavior that contributes to a positive environment for our
community includes:

* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback

   others can pick up where they left off.

This code is not exhaustive or complete. It serves to distill our common understanding of a
collaborative, shared environment, and goals. We expect it to be followed in spirit as much as in
the letter.

# 設定與環境變數 { #settings-and-environment-variables }

在許多情況下，你的應用程式可能需要一些外部設定或組態，例如密鑰、資料庫憑證、電子郵件服務的憑證等。

這些設定大多是可變的（可能會改變），像是資料庫 URL。也有許多可能是敏感資訊，例如密鑰。

因此，通常會透過環境變數提供這些設定，讓應用程式去讀取。

/// tip

若想了解環境變數，你可以閱讀[環境變數](../environment-variables.md)。

## 型別與驗證 { #types-and-validation }

這些環境變數只能處理文字字串，因為它們在 Python 之外，必須與其他程式與系統的其餘部分相容（甚至跨作業系統，如 Linux、Windows、macOS）。

這表示在 Python 中自環境變數讀取到的任何值都會是 `str`，而任何轉型成其他型別或驗證都必須在程式碼中完成。
