在vue中使用js-ipfs上传和显示图像

npm install ipfs

import IPFS from 'ipfs'

const ipfs = await IPFS.create()

async uploadImage(file) {
  const added = await ipfs.add(file)
  const imageHash = added.cid.toString()
  return imageHash
}

async displayImage(imageHash) {
  const chunks = []
  for await (const chunk of ipfs.cat(imageHash)) {
    chunks.push(chunk)
  }
  const imageBuffer = Buffer.concat(chunks)
  const imageUrl = URL.createObjectURL(new Blob([imageBuffer]))
  return imageUrl
}
