A unionid is a WeChat user identifier for an open platform.If the developer has multiple Mobile App, Website App, and Weixin Mini ProgramThe user's unionid can be distinguished by obtaining the user's basic information by obtaining a unionid in the user''s essential information, because as long as the mobile apps, website apps and Mini Programs, small stores and delivery assistants under the same WeChat open platform account, the user' unionid is unique.
