如何使用Uploadset实现挂起的附件？

<template>
  <div>
    <file-upload
      v-model="files"
      post-action="/upload"
      :multiple="true"
      :drop="true"
      :drop-directory="true"
      @input-file="inputFile"
    >
      <button type="button">Select Files</button>
    </file-upload>
  </div>
</template>

<script>
import FileUpload from 'vue-upload-component'

export default {
  components: {
    FileUpload
  },
  data() {
    return {
      files: []
    }
  },
  methods: {
    inputFile(newFile, oldFile) {
      if (newFile && !oldFile) {
        newFile.pause()
      }
      if (oldFile && !newFile) {
        oldFile.resume()
      }
    }
  }
}
</script>

const express = require('express')
const multer = require('multer')
const upload = multer({ dest: 'uploads/' })

const app = express()

app.post('/upload', upload.array('files'), (req, res) => {
  res.send('Files uploaded successfully')
})

app.listen(3000, () => {
  console.log('Server is running on port 3000')
})
