vue在axios请求下载文件时，通过headers的[content-disposition]获取文件名称

export async function downloadTwo(url, params, filename) {
  const res = await axios({
    headers: {
      'Content-Type': 'application/json;charset=utf-8',
      'Authorization': 'token'
    },
    method: 'post',
    url: url, // 请求路径
    data: params,
    responseType: 'blob',
  });

  const fileNameEncode = res.headers['content-disposition']
    .split('filename=')[1]
    .split(';')[0];
  const fileName = decodeURI(fileNameEncode, 'utf-8').replaceAll('"', '')
  
  const blob = new Blob([res.data]);
  const urls = URL.createObjectURL(blob);
  const link = document.createElement('a');
  link.style.display = 'none';
  link.setAttribute('href', urls);
  link.setAttribute('download', fileName);
  link.click();
  URL.revokeObjectURL(urls);

}
