终于，我们英雄（hero）的身份得到了保护！ 🥷

它还重新声明了 `id: int` 。这样我们便与 API 客户端建立了一种**约定**，使他们始终可以期待 `id` 存在并且是一个整数 `int`（永远不会是 `None` ）。

/// tip

确保返回模型始终提供一个值并且始终是 `int` （而不是 `None` ）对 API 客户端非常有用，他们可以在这种确定性下编写更简单的代码。

此外，**自动生成的客户端**将拥有更简洁的接口，这样与您的 API 交互的开发者就能更轻松地使用您的 API。😎

///

`HeroPublic` 中的所有字段都与 `HeroBase` 中的相同，其中 `id` 声明为 `int` （不是 `None` ）：

* `id`
* `name`
* `age`
* `secret_name`
