Ao implementar o callback por conta própria, você pode usar algo como [HTTPX](https://www.python-httpx.org) ou [Requests](https://requests.readthedocs.io/).

## Escreva o código de documentação do callback { #write-the-callback-documentation-code }

Esse código não será executado em seu aplicativo, nós só precisamos dele para *documentar* como essa *API externa* deveria ser.

`UploadFile` 具有以下 `async` 方法。它们都会在底层调用对应的文件方法（使用内部的 `SpooledTemporaryFile`）。

* `write(data)`：将 `data` (`str` 或 `bytes`) 写入文件。
* `read(size)`：读取文件中 `size` (`int`) 个字节/字符。
* `seek(offset)`：移动到文件中字节位置 `offset` (`int`)。
    * 例如，`await myfile.seek(0)` 会移动到文件开头。
    * 如果你先运行过 `await myfile.read()`，然后需要再次读取内容时，这尤其有用。
