如何将Google actions dialogflow与hapi nodejs框架集成？

const { SessionsClient } = require('@google-cloud/dialogflow');

const projectId = 'your-project-id';
const sessionId = 'your-session-id';
const languageCode = 'en-US';

const sessionClient = new SessionsClient();
const sessionPath = sessionClient.projectAgentSessionPath(projectId, sessionId);

async function dialogflowMiddleware(request, h) {
  const { queryText, languageCode } = request.payload;

  const request = {
    session: sessionPath,
    queryInput: {
      text: {
        text: queryText,
        languageCode: languageCode,
      },
    },
  };

  const responses = await sessionClient.detectIntent(request);
  const result = responses[0].queryResult;

  return h.response(result.fulfillmentText).code(200);
}

const Hapi = require('@hapi/hapi');

const server = Hapi.server({
  port: 3000,
  host: 'localhost',
});

server.route({
  method: 'POST',
  path: '/dialogflow',
  handler: dialogflowMiddleware,
});

async function startServer() {
  try {
    await server.start();
    console.log('Server running on %s', server.info.uri);
  } catch (err) {
    console.error('Error starting server:', err);
  }
}

startServer();
