import ( "github.com/juju/juju/apiserver/common" ) func checkAuthorization(auth common.Authorizer) error { if err := auth.Authorize("user123", "serviceA"); err != nil { return err } return nil }
import ( "github.com/juju/juju/apiserver/common" ) func manageAuthModel(manager *common.AuthModelManager) error { // Add a new user to the authentication model err := manager.AddUser("user123", "password123") if err != nil { return err } // Authenticate the user err = manager.Authenticate("user123", "password123") if err != nil { return err } // Remove the user from the authentication model err = manager.RemoveUser("user123") if err != nil { return err } return nil }In this example, we are using the AuthModelManager type to manage the authentication model. We add a new user with the ID "user123" and password "password123", authenticate the user, and then remove the user from the model. If any of these operations fail, the function returns an error. Overall, the "github.com/juju/juju/apiserver/common" package provides useful components for authentication and authorization in Go applications.
