`root_path` 用于处理这些特定情况。

在挂载子应用时，也可以在内部使用。

## 移除路径前缀的代理

本例中，移除路径前缀的代理是指在代码中声明路径 `/app`，然后在应用顶层添加代理，把 **FastAPI** 应用放在 `/api/v1` 路径下。

本例的原始路径 `/app` 实际上是在 `/api/v1/app` 提供服务。

哪怕所有代码都假设只有 `/app`。

代理只在把请求传送给 Uvicorn 之前才会**移除路径前缀**，让应用以为它是在 `/app` 提供服务，因此不必在代码中加入前缀 `/api/v1`。

但之后，在（前端）打开 API 文档时，代理会要求在 `/openapi.json`，而不是 `/api/v1/openapi.json` 中提取 OpenAPI 概图。
