我有一个文件示例，是我从强大的图书馆得到的。看起来像这样

photo: File {
    _events: [Object: null prototype] {},
    _eventsCount: 0,
    _maxListeners: undefined,
    size: 16648,
    path: 'public/upload_1.jpg',
    name: 'test.jpg',
    type: 'image/jpeg',
    hash: null,
    lastModifiedDate: 2021-07-08T11:22:05.804Z,
    _writeStream: WriteStream {
      _writableState: [WritableState],
      writable: false,
      _events: [Object: null prototype] {},
      _eventsCount: 0,
      _maxListeners: undefined,
      path: 'public/upload_1.jpg',
      fd: null,
      flags: 'w',
      mode: 438,
      start: undefined,
      autoClose: true,
      pos: undefined,
      bytesWritten: 16648,
      closed: false
    }
  }

现在，我需要将此图像传递给一个外部nodejs api，该api希望该图像在

req.file('photo')

格式。
请帮助如何将上述示例发送到nodejsapi。
提前谢谢
