1. 이것이 제너레이터 함수입니다. `yield` 문을 포함하고 있으므로 "제너레이터 함수"입니다.
2. `with` 블록을 사용함으로써, 제너레이터 함수가 완료된 후 파일과 같은 객체가 닫히도록 합니다. 즉, 응답 전송이 끝난 후 닫힙니다.
3. 이 `yield from`은 함수가 `file_like`라는 객체를 반복(iterate)하도록 합니다. 반복된 각 부분은 이 제너레이터 함수(`iterfile`)에서 생성된 것처럼 `yield` 됩니다.

    이렇게 하면 "생성(generating)" 작업을 내부적으로 다른 무언가에 위임하는 제너레이터 함수가 됩니다.

some_file_path = "large-video-file.mp4"
app = FastAPI()


@app.get("/")
def main():
    def iterfile():  # (1)
        with open(some_file_path, mode="rb") as file_like:  # (2)
            yield from file_like  # (3)

OAuth2 specifies that when using the "password flow" (that we are using) the client/user must send a `username` and `password` fields as form data.

And the spec says that the fields have to be named like that. So `user-name` or `email` wouldn't work.

But don't worry, you can show it as you wish to your final users in the frontend.
