Authorized login (non-silent authorization): The user is required to confirm the login, so that the user's personal confirmation can be used to obtain comprehensive information of the user, regardless of whether they follow the relevant WeChat public account or not.
Silent authorization does not require user confirmation, but only requires the user to visit a certain webpage. It is an authorization form nested in an ordinary webpage, but only the user's unique identifiers openid and union id can be obtained, but the
user's WeChat avatar and WeChat name cannot be obtained. Such as personal information, it is still very useful for simple authentication of users.
