+## Authorization
+
+A simple permission verification method is also provided
+```go
+type ACL interface {
+	GetPermission(id string) []string
+}
+```
+```go
+type RBAC interface {
+	GetRole(id string) []string
+}
+```
+Implement either of these two interfaces and call `enforcer.SetAuth(model)`
+After that, you can use these two APIs for permission verification
+
+``` go
+// implement RBAC
+CheckRole(ctx ctx.Context, role string) error
+// implement ACL
+CheckPermission(ctx ctx.Context, permission string) error
+```
