It's not acceptable to treat an unset Provider as if the convention is requested when the convention could be set elsewhere:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}

// Unacceptable
String value
if (!getSomeProperty().isPresent()) {
   value = "convention"
} else {
   value = getSomeProperty().get()
}

        assertEquals(TransPeekNamedPipeResponse.STATUS_DISCONNECTED, response.getStatus());
    }

この例では、架空のカスタムヘッダー `X-Key` と `X-Token` を使用しています。

しかし実際のケースでセキュリティを実装する際は、統合された[Security utilities（次の章）](../security/index.md)を使うことで、より多くの利点を得られます。
