Genau so, wie wir es wollten. ✔️

Dies liegt daran, dass FastAPI diesen `root_path` verwendet, um den Default-`server` in OpenAPI mit der von `root_path` bereitgestellten URL zu erstellen.

## Zusätzliche Server

/// warning | "Achtung"

Dies ist ein fortgeschrittener Anwendungsfall. Überspringen Sie das gerne.

///

Standardmäßig erstellt **FastAPI** einen `server` im OpenAPI-Schema mit der URL für den `root_path`.

<img src="/img/tutorial/behind-a-proxy/image02.png">

一切正常。 ✔️

这是因为 FastAPI 在 OpenAPI 里使用 `root_path` 提供的 URL 创建默认 `server`。

## 附加的服务器

/// warning | "警告"

此用例较难，可以跳过。

///

默认情况下，**FastAPI** 使用 `root_path` 的链接在 OpenAPI 概图中创建 `server`。

但也可以使用其它备选 `servers`，例如，需要同一个 API 文档与 staging 和生产环境交互。

Once we determine the proxy may be impacted, we determine which *types* may be impacted. For example, we know a `WasmPlugin` does not impact the `Cluster` type, so we can skip generating `Cluster` in this case. Warning: Envoy currently has a bug that *requires* `Endpoints` to be pushed any time the corresponding `Cluster` is pushed, so this optimization is intentionally turned off in this specific case.

이미 **FastAPI**의 **0.99.0 혹은 그 이상** 버전을 사용하고 있다면, 이 세부 사항을 **스킵**해도 상관 없을 것입니다.

세부 사항은 OpenAPI 3.1.0이 사용가능하기 전, 예전 버전과 더 관련있습니다.

간략한 OpenAPI와 JSON 스키마 **역사 강의**로 생각할 수 있습니다. 🤓

표준 **JSON 스키마**와 **OpenAPI**에 대한 아주 기술적인 세부사항입니다.
