前後端分離時，介面返回時要注意headers　

def exportExcel():
  workbook = xlwt.Workbook(encoding='utf-8')
  wSheet = workbook.add_sheet("Plan")
  titleFont = xlwt.Font()
  f = BytesIO()
  workbook.save(f)
  f.seek(0)
  filename = quote(saveFile) # 將單個字串編碼轉化為 %xx%xx 的形式
  rv = send_file(f,attachment_filename=filename)
  rv.headers['Content-Disposition'] += "; filename*=utf-8''{}".format(filename)
  rv.headers['Cache-Control'] = 'no-store'      # 重點在這句！！！！！！！！！！！！！！！！！
  return rv
