다음으로, <a href="http://127.0.0.1:8000/subapi/docs" class="external-link" target="_blank">http://127.0.0.1:8000/subapi/docs</a>에서 하위 응용프로그램의 문서를 여십시오.

하위 경로 접두사 `/subapi` 아래에 선언된 *경로 동작* 을 포함하는, 하위 응용프로그램에 대한 자동 API 문서를 확인할 수 있습니다:

下图显示的是主应用 API 文档，只包括其自有的*路径操作*。

然后查看子应用文档 <a href="http://127.0.0.1:8000/subapi/docs" class="external-link" target="_blank">http://127.0.0.1:8000/subapi/docs。</a>

下图显示的是子应用的 API 文档，也是只包括其自有的*路径操作*，所有这些路径操作都在 `/subapi` 子路径前缀下。

两个用户界面都可以正常运行，因为浏览器能够与每个指定的应用或子应用会话。

# Sub-dependencies { #sub-dependencies }

You can create dependencies that have **sub-dependencies**.

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:
