示例1: GetCurrentModel
// GetCurrentModel returns the name of the current Juju model.
//
// If $JUJU_MODEL is set, use that. Otherwise, get the current
// controller from controllers.yaml, and then identify the current
// model for that controller in models.yaml. If there is no current
// controller, then an empty string is returned. It is not an error
// to have no current model.
//
// If there is a current controller, but no current model for that
// controller, then GetCurrentModel will return the string
// "<controller>:". If there is a current model as well, it will
// return "<controller>:<model>". Only when $JUJU_MODEL is set,
// will the result possibly be unqualified.
func GetCurrentModel(store jujuclient.ClientStore) (string, error) {
