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

### Die Haupt-Anwendungsdatei

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

### O arquivo principal da aplicação

Agora criamos a dependência que retorna um novo objeto `config.Settings()`.

Notice that now we don't create a default instance `settings = Settings()`.

### The main app file

Now we create a dependency that returns a new `config.Settings()`.

/// tip

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：

import org.apache.maven.settings.Profile;
import org.apache.maven.settings.Proxy;
import org.apache.maven.settings.Repository;
import org.apache.maven.settings.Server;
import org.apache.maven.settings.Settings;
import org.apache.maven.settings.SettingsUtils;

    repo = g.get_repo(settings.github_repository)
