文件将作为「表单数据」上传。

如果把*路径操作函数*参数的类型声明为 `bytes`，**FastAPI** 会为你读取文件，并以 `bytes` 的形式接收其内容。

请注意，这意味着整个内容会存储在内存中，适用于小型文件。

不过，在很多情况下，使用 `UploadFile` 会更有优势。

## 含 `UploadFile` 的文件参数 { #file-parameters-with-uploadfile }

将文件参数的类型声明为 `UploadFile`：

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

与 `bytes` 相比，使用 `UploadFile` 有多项优势：

* 无需在参数的默认值中使用 `File()`。
* 它使用“spooled”文件：

  /**
   * Peeks up to [byteCount] bytes from the response body and returns them as a new response
   * body. If fewer than [byteCount] bytes are in the response body, the full response body is
   * returned. If more than [byteCount] bytes are in the response body, the returned value
   * will be truncated to [byteCount] bytes.
   *
   * It is an error to call this method after the body has been consumed.
