## Details about the `Request` object { #details-about-the-request-object }

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's [`Request`](https://www.starlette.dev/requests/) object directly when you need to.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## Recap { #recap }

You could use these tools and ideas if you are setting up **your own deployment system** while taking care of the other deployment concepts yourself.

## 安全性 - HTTPS { #security-https }

在[前一章關於 HTTPS](https.md) 中，我們學到 HTTPS 如何為你的 API 提供加密。

我們也看到，HTTPS 通常由應用伺服器外部的元件提供，即 TLS Termination Proxy。

而且必須有某個東西負責續期 HTTPS 憑證，可能是同一個元件，也可能是不同的東西。

### HTTPS 工具範例 { #example-tools-for-https }

你可以用來作為 TLS Termination Proxy 的工具包括：

- Traefik
    - 自動處理憑證續期 ✨
- Caddy
    - 自動處理憑證續期 ✨
- Nginx
    - 搭配像 Certbot 這類外部元件進行憑證續期
- HAProxy
    - 搭配像 Certbot 這類外部元件進行憑證續期
