通过API接口获取到数据（数据是后台添加，后台添加应该都是mgnt_api）

    {
      "as": "username",
      "at": "2023-09-27T13:39:25+08:00",
      "by": "mgmt_api",
      "reason": "禁止大巴山用户名",
      "until": "2023-09-29T00:00:00+08:00",
      "who": "dabashan"
    }

通过API添加禁用

{
  "as": "username",
  "who": "dabashan",
  "by": "dabashanapi",
  "reason": "接口示范封禁大巴山到黑明单",
  "at": "2021-10-27T21:48:47+08:00",
  "until": "2021-10-27T21:53:47+08:00"
}
