How to use the st2client.models.core.Resource function in st2client

def run(self, args, **kwargs):
        payload = core.Resource()
        payload.command = args.command_text
        payload.user = args.user
        payload.source_channel = 'cli'

        alias_execution_mgr = self.app.client.managers['ActionAliasExecution']
        execution = alias_execution_mgr.match_and_execute(payload)
        return execution
