variáveis ​​de ambiente seriam úteis e aplicáveis ​​imediatamente. Mas elas continuam aparecendo em muitos cenários diferentes quando você está desenvolvendo, então é bom saber sobre elas.

[前チャプターのHTTPSについて](https.md)では、HTTPSがどのようにAPIを暗号化するのかについて学びました。

通常、アプリケーションサーバにとって**外部の**コンポーネントである**TLS Termination Proxy**によって提供されることが一般的です。このプロキシは通信の暗号化を担当します。

さらに、HTTPS証明書の更新を担当するものが必要で、同じコンポーネントが担当することもあれば、別のコンポーネントが担当することもあります。

### HTTPS 用ツールの例 { #example-tools-for-https }
TLS Termination Proxyとして使用できるツールには以下のようなものがあります：

* Traefik
    * 証明書の更新を自動的に処理 ✨
* Caddy
    * 証明書の更新を自動的に処理 ✨
* Nginx

                A path prefix handled by a proxy that is not seen by the application
                but is seen by external clients, which affects things like Swagger UI.

                Read more about it at the
                [FastAPI docs for Behind a Proxy](https://fastapi.tiangolo.com/advanced/behind-a-proxy/).

                **Example**

                ```python

	return sha256Sum, releaseTime, releaseInfo, err
}

func getUpdateTransport(timeout time.Duration) http.RoundTripper {
	var updateTransport http.RoundTripper = &http.Transport{
		Proxy:                 http.ProxyFromEnvironment,
		DialContext:           xhttp.NewInternodeDialContext(timeout, globalTCPOptions),
		IdleConnTimeout:       timeout,
		TLSHandshakeTimeout:   timeout,
