### FastAPI `HTTPException` vs Starlette `HTTPException`

**FastAPI** 也提供了自有的 `HTTPException`。

**FastAPI** 的 `HTTPException` 继承自 Starlette 的 `HTTPException` 错误类。

它们之间的唯一区别是，**FastAPI** 的 `HTTPException` 可以在响应中添加响应头。

OAuth 2.0 等安全工具需要在内部调用这些响应头。

因此你可以继续像平常一样在代码中触发 **FastAPI** 的 `HTTPException` 。

但注册异常处理器时，应该注册到来自 Starlette 的 `HTTPException`。

Por ejemplo, ampliando el modelo anterior, podrías decidir que deseas tener otra clave `importance` en el mismo cuerpo, además de `item` y `user`.

Si lo declaras tal cual, debido a que es un valor singular, **FastAPI** asumirá que es un parámetro de query.

Pero puedes instruir a **FastAPI** para que lo trate como otra clave del cuerpo usando `Body`:
