type Enforcer struct {
	*casbin.Enforcer
}

func NewDatabaseEnforcer

func NewDatabaseEnforcer(c *conf.Data_Database) (*Enforcer, error)

NewDatabaseEnforcer creates a new casbin authorization enforcer based on a database backend as policies storage backend

func NewFiletypeEnforcer

func NewFiletypeEnforcer(path string) (*Enforcer, error)
