# 子应用 - 挂载 { #sub-applications-mounts }

如果需要两个独立的 FastAPI 应用，拥有各自独立的 OpenAPI 与文档，则需设置一个主应用，并**挂载**一个（或多个）子应用。

## 挂载 **FastAPI** 应用 { #mounting-a-fastapi-application }

**挂载**是指在特定路径中添加完全**独立**的应用，然后在该路径下使用*路径操作*声明的子应用处理所有事务。

### 顶层应用 { #top-level-application }

首先，创建主（顶层）**FastAPI** 应用及其*路径操作*：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 子应用 { #sub-application }

接下来，创建子应用及其*路径操作*。
