下面的代码示例获取上载的文件的文件详细信息。此方法获取文件的上传 ID 和文件的交易 ID。交易 ID 可以通过 getUploads 方法获取

require('dotenv').config()
const { mcsSDK } = require('js-mcs-sdk')
const fs = require('fs') // used to read files

// set up js-mcs-sdk
const mcs = new mcsSDK({
  privateKey: process.env.PRIVATE_KEY,
  rpcUrl: process.env.RPC_URL,
})

async function main() {
  // ENTER PARAMETERS
  const SOURCE_FILE_UPLOAD_ID = ''
  const DEAL_ID = ''
   
  console.log(await mcs.getFileDetails(SOURCE_FILE_UPLOAD_ID, DEAL_ID))
}

main()

• sourceFileUploadId：文件的上传 ID

• dealId： 文件的 deal id
