相対URLを使っているので、APIが`https://example.com/`にある場合、`https://example.com/token`を参照します。しかし、APIが`https://example.com/api/v1/`にある場合は`https://example.com/api/v1/token`を参照することになります。

相対 URL を使うことは、[プロキシの背後](../../advanced/behind-a-proxy.md)のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

///

このパラメーターはエンドポイント/ *path operation*を作成しません。しかし、URL`/token`はクライアントがトークンを取得するために使用するものであると宣言します。この情報は OpenAPI やインタラクティブな API ドキュメントシステムで使われます。

这样，应用就能知道自己的公共 URL、是否使用 HTTPS、域名等信息。

这在需要正确处理重定向等场景时很有用。

## 回顾 { #recap }

拥有**HTTPS** 非常重要，并且在大多数情况下相当**关键**。 作为开发人员，你围绕 HTTPS 所做的大部分努力就是**理解这些概念**以及它们的工作原理。

Cela serait utile, par exemple, pour gérer correctement les redirections.

## 컨테이너란 { #what-is-a-container }

* Each application that you have running on your computer has some process behind it, each running program, each window, etc. And there are normally many processes running **at the same time** while a computer is on.
* There can be **multiple processes** of the **same program** running at the same time.

이렇게 하면 애플리케이션은 자신이 사용하는 공개 URL이 무엇인지, HTTPS를 사용하는지, 도메인이 무엇인지 등을 알 수 있습니다.

예를 들어 리다이렉트를 올바르게 처리하는 데 유용합니다.

## 요약 { #recap }

**HTTPS**는 매우 중요하며, 대부분의 경우 상당히 **핵심적**입니다. 개발자가 HTTPS와 관련해 해야 하는 노력의 대부분은 결국 **이 개념들을 이해**하고 그것들이 어떻게 동작하는지 파악하는 것입니다.
