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

## 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!}
```
