## 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。

如果传递自定义 `servers` 列表，并有 `root_path`（ 因为 API 使用了代理），**FastAPI** 会在列表开头使用这个 `root_path` 插入**服务器**。

例如：

```Python hl_lines="4-7"
{!../../../docs_src/behind_a_proxy/tutorial003.py!}
```

aizubange.fukushima.jp aizumi.tokushima.jp aizumisato.fukushima.jp aizuwakamatsu.fukushima.jp aju.br ak.us akabira.hokkaido.jp akadns.net akagi.shimane.jp akaiwa.okayama.jp akamai-staging.net akamai.net akamaiedge-staging.net akamaiedge.net akamaihd-staging.net akamaihd.net akamaiorigin-staging.net akamaiorigin.net akamaized-staging.net akamaized.net akashi.hyogo.jp akdn aki.kochi.jp akiruno.tokyo.jp akishima.tokyo.jp akita.akita.jp akita.jp akkeshi.hokkaido.jp aknoluokta.no ako.hyogo.jp akrehamn.no aktyubinsk.su...

By default, **FastAPI** will create a `server` in the OpenAPI schema with the URL for the `root_path`.

But you can also provide other alternative `servers`, for example if you want *the same* docs UI to interact with a staging and production environments.

If you pass a custom list of `servers` and there's a `root_path` (because your API lives behind a proxy), **FastAPI** will insert a "server" with this `root_path` at the beginning of the list.

Sie können aber auch andere alternative `server` bereitstellen, beispielsweise wenn Sie möchten, dass *dieselbe* Dokumentationsoberfläche mit einer Staging- und Produktionsumgebung interagiert.
