# Sub Applications - Mounts

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

## Mounting a **FastAPI** application

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

`get_openapi()` 函数接收如下参数：

* `title`：文档中显示的 OpenAPI 标题
* `version`：API 的版本号，例如 `2.5.0`
* `openapi_version`： OpenAPI 规范的版本号，默认为最新版： `3.0.2`
* `description`：API 的描述说明
* `routes`：路由列表，每个路由都是注册的*路径操作*。这些路由是从 `app.routes` 中提取的。

## 覆盖默认值

`get_openapi()` 工具函数还可以用于生成 OpenAPI 概图，并利用上述信息参数覆盖指定的内容。
