* For generic errors from the client, you can just use `400`.
* `500` and above are for server errors. You almost never use them directly. When something goes wrong at some part in your application code, or server, it will automatically return one of these status codes.

该命令行程序 `fastapi` 就是 **FastAPI CLI**。

FastAPI CLI 接收你的 Python 程序路径，自动检测包含 FastAPI 的变量（通常命名为 `app`）及其导入方式，然后启动服务。

파일과 폼 필드는 폼 데이터 형식으로 업로드되어 파일과 폼 필드로 전달됩니다.

어떤 파일들은 `bytes`로, 또 어떤 파일들은 `UploadFile`로 선언할 수 있습니다.

/// warning | "경고"

다수의 `File`과 `Form` 매개변수를 한 *경로 작동*에 선언하는 것이 가능하지만, 요청의 본문이 `application/json`가 아닌 `multipart/form-data`로 인코딩 되기 때문에 JSON으로 받아야하는 `Body` 필드를 함께 선언할 수는 없습니다.

이는 **FastAPI**의 한계가 아니라, HTTP 프로토콜에 의한 것입니다.
