注销申请图片上传(平台收付通)

电商平台服务商调用注销申请接口时，需要先调用本接口上传相关的资料图片，获取图片ID后，再填写到注销申请请求中。

const { createReadStream } = require('fs')
const { basename } = require('path');

let localFilePath = '/path/to/merchant-certificate-file.jpg'
const stream = createReadStream(localFilePath)
const meta = {
  file_name: basename(localFilePath),
  file_digest: 'from upstream or local calculated',
}
const media = {
  meta: JSON.stringify(meta),
  file: stream,
}

wxpay.v3.ecommerce.account.cancelApplications.media.post(media, {
  meta,
  headers: { 'Content-Type': 'multipart/form-data' },
})
.then(
  ({ 
    data: {
      media_id,
    },
  }) => ({
    media_id,
  })
)
