前端导出文件，后端返回文件流过大直接干崩溃

export function exportZip(res, name) {
  const blob = new Blob([res.data], {
    type: 'application/zip'
  })
  const reader = new FileReader()
  reader.readAsDataURL(blob)
  reader.onload = function (e) {
    const a = document.createElement('a')
    a.download = `${name}.zip`
    a.href = e.target.result
    // 兼容触发click
    const evt = document.createEvent('MouseEvents')
    evt.initEvent('click', true, true)
    a.dispatchEvent(evt)
  }
}

      <a @click="downFile()">{{文件名称}}</a>
      //下载方法
      downZip () {
        let a = document.createElement('a')
        a.href = '这里是后端同学返回的地址'
        a.click()
      }
  ```

export function exportZip(res, name) {
  const blob = new Blob([res.data], {
    type: 'application/zip'
  })
  saveAs(blob, name)
}
