axios下载excel文件

const res = await this.$axios({
  method: 'get',
  url: ``,
  headers: {},
  responseType: 'blob',
})
const blob = new Blob([res.data], {
  type: 'application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
})
const downloadElement = document.createElement('a')
const href = window.URL.createObjectURL(blob)
downloadElement.style.display = 'none'
downloadElement.href = href
downloadElement.download = row.fileName //下载后文件名
document.body.appendChild(downloadElement)
downloadElement.click() //点击下载
document.body.removeChild(downloadElement) //下载完成移除元素
window.URL.revokeObjectURL(href) //释放掉blob对象
注意:设置 responseType: "blob" 无效时
 
解决办法:
mock模块会影响原生的ajax请求,使得服务器返回的blob类型变成乱码
