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：
    * 檔案在記憶體中保存到某個大小上限，超過上限後會存到磁碟。
* 因此適合處理大型檔案（例如圖片、影片、大型二進位檔等），而不會耗盡記憶體。
* 你可以取得上傳檔案的中繼資料。
* 它提供一個[file-like](https://docs.python.org/3/glossary.html#term-file-like-object) 的 `async` 介面。
* 它會提供實際的 Python [`SpooledTemporaryFile`](https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile) 物件，你可以直接傳給需要類檔案物件的其他函式或函式庫。

The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

then it is a "callable".
