但 FastAPI（实际上是 Starlette）提供了一种更简单的方式，能让内部中间件在处理服务器错误的同时，还能让自定义异常处理器正常运作。

为此，要使用 `app.add_middleware()` （与 CORS 中的示例一样）。

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

/// note | Технічні деталі

Ви також можете використати `from starlette import status`.

**FastAPI** надає ті ж самі змінні `starlette.status` як `fastapi.status`, просто для зручності розробника. Однак вони походять безпосередньо зі Starlette.

## Ein Docker-Image mit einem Single-File-FastAPI erstellen { #build-a-docker-image-with-a-single-file-fastapi }

Wenn Ihr FastAPI eine einzelne Datei ist, zum Beispiel `main.py` ohne ein `./app`-Verzeichnis, könnte Ihre Dateistruktur wie folgt aussehen:
