文档在此 https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/2.0/api/Mini_Program_Basic_Info/Server_Address_Configuration.html

{
  "action": "set",
  "requestdomain": ["https://www.xx.com"],
  "wsrequestdomain": [],
  "uploaddomain": ["https://www.xx.com"],
  "downloaddomain": ["https://www.xx.com"],
  "udpdomain": [],
  "tcpdomain": []
}

调用设置接口正常，但是 action 设为 get 再去调接口时，返回的 uploaddomain 和 downloaddomain 为空，请问这是什么问题？
