我是一个 Discourse 社区的用户，我想知道是否有任何方法来通过 user ID 获取用户名。或者从用户 nickname 获取用户名。
You may want to look at this topic. AFAIK you can’t access a user route with the user id like /u/id. Also the API docs are on getting user info from the user id are only by the admin route, it seems:

Why do you need that information?
A quite hacky way is to search for user:USERID. For example, user:95552 and then you can find out more about me by looking at my profile.
An admin could also create a data explorer query that returns the data you need based on the userID. They can give access to it to a group, and you being a member of the group, could use it.
