getUsersInfoWithCache

Feature Description

Description

Retrieve nicknames and avatars in IM.

Note

(1) It's recommended to request a maximum of 100 at a time as a larger number might result in the backend rejecting the request due to the data packet being too large; (2) Data is primarily fetched from the server. If that fails, it is then retrieved from local cache; (3) When users use this interface to get the personal information of non-friends, the SDK will internally update this cache.
