vue获取文件流并下载

首先封装导出函数

// 导出
const downloadExcel = (response) => {
  const url = window.URL.createObjectURL(new Blob([response.data]));
  const link = document.createElement('a');
  link.href = url;
  let fileName = response.headers['content-disposition'].split("filename*=utf-8''")[1]
  link.setAttribute('download', fileName);
  document.body.appendChild(link);
  link.click();
}

发送请求获取文件

axios.get(exportUrl, { params: data, responseType: 'blob' }).then(res => {
    downloadExcel(res)
})
