RBAC problems in thinkphp the content in the think_role_user table is role_iduser_id & nbsp; 11 & nbsp; 22 & nbsp; access permissions are also granted to each user group, however, the problem occurs when my id is not accessible to users 1 and 2. I did not address the RBAC issue in think _ thinkphp.
RBAC problems in thinkphp
The content in the think_role_user table is
Role_id user_id
1 1
2 2
I have also granted access permissions to each user group, but the problem occurs that users whose id is not 1 or 2 can access the table. I did not add other user IDs to the think_role_user table, what other users can access ???
Thank you!
