### Read Heroes with `HeroPublic` { #read-heroes-with-heropublic }

We can do the same as before to **read** `Hero`s, again, we use `response_model=list[HeroPublic]` to ensure that the data is validated and serialized correctly.

### Read One Hero with `HeroPublic` { #read-one-hero-with-heropublic }

///

### Helden mit `HeroPublic` lesen { #read-heroes-with-heropublic }

Wir können dasselbe wie zuvor tun, um `Hero`s zu **lesen**, und erneut verwenden wir `response_model=list[HeroPublic]`, um sicherzustellen, dass die Daten ordnungsgemäß validiert und serialisiert werden.

/// tip | 提示

触发 `HTTPException` 时，可以用参数 `detail` 传递任何能转换为 JSON 的值，不仅限于 `str`。

还支持传递 `dict`、`list` 等数据结构。

**FastAPI** 能自动处理这些数据，并将之转换为 JSON。

## 添加自定义响应头

有些场景下要为 HTTP 错误添加自定义响应头。例如，出于某些方面的安全需要。

一般情况下可能不会需要在代码中直接使用响应头。

但对于某些高级应用场景，还是需要添加自定义响应头：

Además, los **clientes generados automáticamente** tendrán interfaces más simples, para que los desarrolladores que se comuniquen con tu API puedan tener una experiencia mucho mejor trabajando con tu API. 😎
