* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).
* It then takes the **response** generated by the application (by some *path operation*).
* It can do something to that **response** or run any needed code.

Indem Sie nur `BackgroundTasks` (und nicht `BackgroundTask`) verwenden, ist es dann möglich, es als *Pfadoperation-Funktion*-Parameter zu verwenden und **FastAPI** den Rest für Sie erledigen zu lassen, genau wie bei der direkten Verwendung des `Request`-Objekts.

			if !atEOF {
				return 0, nil, nil
			}
			// If we have reached the end, return the last token.
			return 0, data, bufio.ErrFinalToken
		}
		// If the token is "STOP", stop the scanning and ignore the rest.
		if string(data[:i]) == "STOP" {
			return i + 1, nil, bufio.ErrFinalToken
		}
		// Otherwise, return the token before the comma.
		return i + 1, data[:i], nil
	}
	const input = "1,2,STOP,4,"

By only using `BackgroundTasks` (and not `BackgroundTask`), it's then possible to use it as a *path operation function* parameter and have **FastAPI** handle the rest for you, just like when using the `Request` object directly.

It's still possible to use `BackgroundTask` alone in FastAPI, but you have to create the object in your code and return a Starlette `Response` including it.
