Beachten Sie, dass wir jetzt keine Standardinstanz `settings = Settings()` erstellen.

### Die Haupt-Anwendungsdatei

Jetzt erstellen wir eine Abhängigkeit, die ein neues `config.Settings()` zurückgibt.

    如果您需要一个快速的复制粘贴示例，请不要使用此示例，而应使用下面的最后一个示例。

然后，当您创建该 `Settings` 类的实例（在此示例中是 `settings` 对象）时，Pydantic 将以不区分大小写的方式读取环境变量，因此，大写的变量 `APP_NAME` 仍将为属性 `app_name` 读取。

然后，它将转换和验证数据。因此，当您使用该 `settings` 对象时，您将获得您声明的类型的数据（例如 `items_per_user` 将为 `int` 类型）。

### 使用 `settings`

然后，您可以在应用程序中使用新的 `settings` 对象：

```Python hl_lines="18-20"

	for id, rl := range rMap {
		if !rl.Expiration.IsNull() || !rl.NoncurrentVersionExpiration.IsNull() {
			if _, ok := newRMap[id]; !ok {
				// if rule getting removed was pure expiry rule (may be got to this site
				// as part of replication of expiry rules), remove it. Otherwise remove
				// only the expiry part of it
