如何在 nodejs 写的 api 接口中将上传的图片再 post 给另一个 api 接口

我写的 nodejs 接口是基于 koa 框架的，并使用 koa-better-body 将上传的文件解析，解析得到的文件数据如下:

File { _events: [Object: null prototype] {}, _eventsCount: 0, _maxListeners: undefined, size: 297525, path: '/tmp/upload_0be4ede06f899420d94441f9d64ff49d', name: 'AIRBUS_HoF_2018_Screenshot1.jpeg', type: 'image/jpeg', hash: null, lastModifiedDate: 2020-02-12T06:32:46.177Z, _writeStream: WriteStream { _writableState: WritableState { objectMode: false, highWaterMark: 16384, finalCalled: true, needDrain: false, ending: true, ended: true, finished: true, destroyed: true, decodeStrings: true, defaultEncoding: 'utf8', length: 0, writing: false, corked: 0, sync: false, bufferProcessing: false, onwrite: [Function: bound onwrite], writecb: null, writelen: 0, bufferedRequest: null, lastBufferedRequest: null, pendingcb: 0, prefinished: true, errorEmitted: false, emitClose: false, autoDestroy: false, bufferedRequestCount: 0, corkedRequestsFree: [Object] }, writable: false, _events: [Object: null prototype] {}, _eventsCount: 0, _maxListeners: undefined, path: '/tmp/upload_0be4ede06f899420d94441f9d64ff49d', fd: null, flags: 'w', mode: 438, start: undefined, autoClose: true, pos: undefined, bytesWritten: 297525, closed: true } } 

然后如何将图片转发给另一个 api 接口呢（我是打算把图片上传至图床 api ），有没有办法将发送来的 file 数据流直接发个另一个 api，求大佬给个解决思路，只要说一下需要用的库和大概的思路就行，谢谢了
