"htmlcode">

axios.post(
  apiUrl,
  formdata, 
  {responseType:'arraybuffer'}
).then(res=> {
  if (res.status === 200) {
   let blob = new Blob([res.data], {
    type: res.headers['content-type']
    });

    const fileName = res.headers['content-disposition'];
   const title = fileName && (fileName.indexOf('filename=') !== -1) "htmlcode">
from flask import send_from_directory
@admin_bp.route('/tasksothers/download', methods=["GET", "POST"])
@auth.login_required
def api_tasksothers_download():
    root_path = ''
    src_name = "a.sql"
    upload_path = os.path.join(root_path, src_name)
    print("upload_path =", upload_path)
    if os.path.isfile(upload_path):
      response = send_from_directory(root_path, src_name, as_attachment=True)
      print("response: ",response)

      response.headers["Access-Control-Expose-Headers"] = "Content-disposition"
      print("response: ", response.headers)
      return response  

注: 如果 response.header 中没有添加  Access-Control-Expose-Headers 这个参数(代表:服务器允许浏览器访问的头(headers)的白名单),vue中就无法获取 content-disposition,即 res.headers['content-disposition'];无法找到
