In the actual production process, roles are widely used. What is a role? A role is a set of permissions that can be authorized to users or roles to control user access and behavior to objects.

We use user permission management when developing many projects, and I have also done permission control in many projects. Therefore, I have also summarized a clear role permission control system. This article uses the basic concept of Role-Based Access Control (RBAC). The basic idea of Role-Based Access Control can be expressed simply by user-role-permission, the entire access control process is divided into two steps: the access permission is associated with the role, and the role is associate
