在flask应用程序中，我有一个函数，它获取列表列表，并将每个列表作为一行添加到excel文件中。当请求不会超时时，此函数在开发服务器上可以正常工作。在这里它被包裹在一个 try / except 阻止。这就是我需要在prod服务器上将其作为队列任务调用的方式。

def make_excel_file(file_title, lists_to_print):

  try:
    job = get_current_job()

    # returns a list of lists
    # the first list is the header row (titles of attributes)
    # the following lists are all lists of the relevant object attributes
    # as well as some joined object attributes
    # (e.g. user ID, user email, drive year)
    rows = wish_list_rows(lists_to_print)

    wb = Workbook()
    ws = wb.active

    tempfile = NamedTemporaryFile()
    tempfile.name = file_title

    num_rows = len(rows)

    _set_task_progress(0, "excel_progress") #This results in a valid notification
                                            # so I know the function reaches at least this point

    for r in rows:
      ws.append(r)
      wb.save(tempfile)
      tempfile.seek(0)

      _set_task_progress(100.0 * (num_rows/rows.index(r)), "excel_progress") #the number never
                                                                             #updates, so the for loop
                                                                             #must never begin
    stream = tempfile.read()

    response = make_response(stream)
    response.headers['Content-Disposition'] = "attachment; filename={}".format(
      file_title)
    response.mimetype = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
  except:
    flash("Lists could not be exported to Excel.", "warning")
  finally:
    _set_task_progress(100, "excel_progress")
  if response:
    return response

使用本地服务器的redis cli和命令 redis-cli monitor ，可以看到以下输出：

~$ redis-cli monitor

我不知道该怎么解释。我还想帮助理解如何进一步调试和查看本地redis服务器上该函数中发生的事情。
编辑：我现在看到配置到应用程序的队列可能有问题。当我使用get\u current\u job（）从rq获取作业时，我可以访问它。但是，应用程序队列的注册表都是空的。如果redis cli和pythonrq中的redis服务器上确实存在作业，那么什么会阻止应用程序的队列拥有作业呢？
