  - The CoreDNS Deployment now checks readiness via the `ready` plugin.
  - The `proxy` plugin has been deprecated. The `forward` plugin is to be used instead.

  - The `upstream` option is deprecated and ignored if included.

API'lara gereken bir diğer büyük özellik ise veri doğrulamadır, yani verinin çeşitli parametrelere bağlı olarak doğru ve tutarlı olduğundan emin olmaktır. Örneğin bir alanın `int` olmasına karar verdiniz, daha sonra rastgele bir metin değeri almasını istemezsiniz. Bu özellikle sisteme dışarıdan gelen veri için kullanışlı bir özellik oluyor.

Marshmallow und Webargs bieten Validierung, Parsen und Serialisierung als Plugins.

Es fehlt jedoch noch die Dokumentation. Dann wurde APISpec erstellt.

Es ist ein Plugin für viele Frameworks (und es gibt auch ein Plugin für Starlette).

Die Funktionsweise besteht darin, dass Sie die Definition des Schemas im YAML-Format im Docstring jeder Funktion schreiben, die eine Route verarbeitet.

使用 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> 编辑器时，推荐安装 <a href="https://github.com/koxudaxi/pydantic-pycharm-plugin/" class="external-link" target="_blank">Pydantic PyCharm 插件</a>。

该插件用于完善 PyCharm 对 Pydantic 模型的支持，优化的功能如下：

* 自动补全
* 类型检查
* 代码重构
* 查找
* 代码审查
