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

### Die Haupt-Anwendungsdatei

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

### Install `pydantic-settings`

First, install the `pydantic-settings` package:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

    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"

project(":mockwebserver-junit4").name = "mockwebserver3-junit4"
include(":mockwebserver-junit5")
project(":mockwebserver-junit5").name = "mockwebserver3-junit5"

}

include(":okcurl")

`IstioOperatorSpec` defines functional settings at the feature level. Functional settings are those that performs some
function in the Istio control plane without necessarily being tied to any one component that runs in a Deployment.
Component settings are those that necessarily refer to a particular Deployment or Service. For example, the number
of Pilot replicas is a component setting, because it refers to a component which is a Deployment in the

Maven 4 API - Immutable Settings Model

 This is strictly the immutable model for Maven settings in <<<org.apache.maven.api.settings>>> package.

 The following are generated from this model:
