下面是POST的内容

{"action":"add","requestdomain":["https://www.xxxxxxx.com"],"wsrequestdomain":["wss://www.xxxxxxx.com"],"uploaddomain":["https://www.xxxxxxx.com"],"downloaddomain":["https://www.xxxxxxx.com"]}

这是返回的结果

设置服务器域名：

{"errcode":85017,"errmsg":"no domain to modify after filtered, please confirm the domain has been set in miniprogram or open hint: [D0RA8a08391091]"}

action 无论是add 还是set返回的结果都是一样的，但是 设置业务域名 可以设置成功

另外我想咨询下，我通过 这个API

https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/Mini_Programs/Fast_Registration_Interface_document.html

生成的小程序是否需要设置服务域名这一步
