以與 `Body` 或 `Query` 相同的方式建立檔案與表單參數：

{* ../../docs_src/request_forms_and_files/tutorial001_an_py310.py hl[10:12] *}

檔案與表單欄位會作為表單資料上傳，而你將能接收到這些檔案與欄位。

你也可以將部分檔案宣告為 `bytes`，另一些宣告為 `UploadFile`。

/// warning

你可以在一個路徑操作 (path operation) 中宣告多個 `File` 與 `Form` 參數，但不能同時再宣告預期以 JSON 接收的 `Body` 欄位，因為該請求的本文會使用 `multipart/form-data` 而非 `application/json` 進行編碼。

這不是 **FastAPI** 的限制，這是 HTTP 通訊協定本身的規範。
