檔案會以「表單資料」上傳。

如果你將路徑操作函式（path operation function）的參數型別宣告為 `bytes`，**FastAPI** 會替你讀取檔案，你會以 `bytes` 取得內容。

請注意，這表示整個內容會存放在記憶體中，適合小檔案。

但在許多情況下，使用 `UploadFile` 會更好。

## 使用 `UploadFile` 的檔案參數 { #file-parameters-with-uploadfile }

將檔案參數型別設為 `UploadFile`：

{* ../../docs_src/request_files/tutorial001_an_py310.py hl[14] *}

使用 `UploadFile` 相較於 `bytes` 有數個優點：

* 你不必在參數的預設值使用 `File()`。
* 它使用「spooled」檔案：
