**FastAPI**, geliştirici olarak size kolaylık olsun diye `starlette.staticfiles`'ı `fastapi.staticfiles` olarak da sağlar. Ancak aslında doğrudan Starlette'den gelir.

### "Mounting" Nedir { #what-is-mounting }

"Mounting", belirli bir path'te tamamen "bağımsız" bir uygulama eklemek ve sonrasında tüm alt path'leri handle etmesini sağlamak demektir.

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-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.

/// note | 技术细节

你也可以用 `from starlette.staticfiles import StaticFiles`。

**FastAPI** 提供了和 `starlette.staticfiles` 相同的 `fastapi.staticfiles`，只是为了方便你这个开发者。但它确实直接来自 Starlette。

### 什么是“挂载”（Mounting） { #what-is-mounting }

“挂载”表示在特定路径添加一个完全“独立”的应用，然后负责处理所有子路径。

这与使用 `APIRouter` 不同，因为挂载的应用是完全独立的。主应用的 OpenAPI 和文档不会包含已挂载应用的任何内容，等等。

你可以在[高级用户指南](../advanced/index.md)中了解更多。

### 什麼是「掛載」 { #what-is-mounting }

「掛載（mounting）」是指在特定路徑下加入一個完整且「獨立」的應用，之後所有該路徑下的子路徑都由它處理。

這與使用 `APIRouter` 不同，因為被掛載的應用是完全獨立的。主應用的 OpenAPI 與文件不會包含掛載應用的任何內容，等等。
