/// 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：

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

val graalBuild: String by settings
val loomBuild: String by settings

if (androidBuild.toBoolean()) {
  include(":regression-test")
}

if (graalBuild.toBoolean()) {
  include(":native-image-tests")
}

include(":okcurl")

controlled by the [`x509sha1` setting](/pkg/crypto/x509#InsecureAlgorithmError).
This setting will be removed in a future release, Go 1.22 at the earliest.

### Go 1.10

Go 1.10 changed how build caching worked and added test caching, along
with the [`gocacheverify`, `gocachehash`, and `gocachetest` settings](/cmd/go/#hdr-Build_and_test_caching).
There is no plan to remove these settings.

### Go 1.6
