The files and form fields will be uploaded as form data and you will receive the files and form fields.

And you can declare some of the files as `bytes` and some as `UploadFile`.

在這個範例中，我們沒有宣告任何 Pydantic 模型。事實上，請求本文甚至不會被 <dfn title="從某種純格式（例如 bytes）轉換為 Python 物件">解析</dfn> 為 JSON，而是直接以 `bytes` 讀取，並由函式 `magic_data_reader()` 以某種方式負責解析。

儘管如此，我們仍可宣告請求本文的預期結構。
