    }

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：

{* ../../docs_src/settings/tutorial001.py hl[18:20] *}

### 运行服务器

接下来，您将运行服务器，并将配置作为环境变量传递。例如，您可以设置一个 `ADMIN_EMAIL` 和 `APP_NAME`，如下所示：

<div class="termy">

```console

	// Append the api label for the drive API latencies.
	labels = append(labels, "api", "")
	lastIdx := len(labels) - 1
	for apiName, latency := range disk.Metrics.LastMinute {
		labels[lastIdx] = "storage." + apiName
		m.Set(driveAPILatencyMicros, float64(latency.Avg().Microseconds()),
			labels...)
	}
}

  <uses-permission android:name="android.permission.INTERNET" />

  <application
    android:allowBackup="true"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:name=".TestApplication"
  >
    <activity
      android:name=".MainActivity"
      android:exported="true">
      <intent-filter>

    return test_main_mod


def test_settings(main_mod: ModuleType, monkeypatch: MonkeyPatch):
    monkeypatch.setenv("ADMIN_EMAIL", "******@****.***")
    settings = main_mod.get_settings()
    assert settings.app_name == "Awesome API"
    assert settings.items_per_user == 50
