axios下载文件流

封装axios

export const exportExcel = (data) => {
  return request({
    url: '/api/fill/exportExcel',
    method: 'post',
    data,
    responseType: 'blob',
  })
}

文件下载

exportExcel(param).then((res) => {
        // 取后端给前端返的请求头中的文件名称
        const temp =res.headers["content-disposition"].split(";")[1].split("filename=")[1];
        const fileName = decodeURIComponent(temp)
        const blob = new Blob([res.data])
        const url = URL.createObjectURL(blob)
        const link = document.createElement('a')
        link.href = url
        link.download = fileName
        document.body.appendChild(link)
        link.click()
      }).catch((res) => {
        console.log(res)
      });
