最簡單的 FastAPI 檔案可能看起來像這樣：

將其複製到一個名為 `main.py` 的文件中。

## Agregando middlewares ASGI

Como **FastAPI** está basado en Starlette e implementa la especificación <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>, puedes usar cualquier middleware ASGI.

Un middleware no tiene que estar hecho para FastAPI o Starlette para funcionar, siempre que siga la especificación ASGI.
