由于 `Response` 经常用于设置头部和 cookies，**FastAPI** 还在 `fastapi.Response` 中提供了它。

///

## 自定义头部 { #custom-headers }

请注意，可以通过[使用 `X-` 前缀](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)添加自定义专有头部。

Und es gab bereits eine Web-Oberfläche für Swagger-APIs. Die Möglichkeit, Swagger-Dokumentation für eine API zu generieren, würde die automatische Nutzung dieser Web-Oberfläche ermöglichen.

Irgendwann wurde Swagger an die Linux Foundation übergeben und in OpenAPI umbenannt.

/// tip | Dica

Tenha em mente que cabeçalhos proprietários personalizados podem ser adicionados [usando o prefixo `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

/// note | 技术细节

这些代理请求头包括：

* [X-Forwarded-For](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-For)
* [X-Forwarded-Proto](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-Proto)
* [X-Forwarded-Host](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-Host)

///

不过，由于**应用服务器**并不知道自己位于受信任的**代理**之后，默认情况下，它不会信任这些请求头。

# Conceptos de Implementación { #deployments-concepts }

Cuando implementas una aplicación **FastAPI**, o en realidad, cualquier tipo de API web, hay varios conceptos que probablemente te importen, y al entenderlos, puedes encontrar la **forma más adecuada** de **implementar tu aplicación**.

Algunos de los conceptos importantes son:

* Seguridad - HTTPS
* Ejecución al iniciar
* Reinicios
* Replicación (la cantidad de procesos en ejecución)
* Memoria

그리고 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용될 수 있으므로, **FastAPI**는 `fastapi.Response`로도 이를 제공합니다.

///

## 커스텀 헤더 { #custom-headers }

커스텀 사설 헤더는 [`X-` 접두어를 사용하여](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers) 추가할 수 있다는 점을 기억하세요.
