我构建了一个node js项目，后来尝试重新安排代码，使文件夹结构符合我的新要求。

旧结构

|-controller
|   |--docController.js
|-index.js

字符串

较新的文件结构

|-adapter/express
|  |--controller
|     |---docController.js
|-route
|  |--docRoute.js
|-frameworks
|  |--app.js
|  |--server.js

对于新的结构，我不得不在代码中做一些修改，比如将routes从index.js分离到专用的route.js。将index.js拆分为server和app.js
现在我的服务器正在运行，但每当我击中我的API，它是无法定位路由。

App.js

const docRoutes = require('./../adapters/express/routes/docRoutes');

const app = express();

app.use('/', docRoutes);
// app.all('*', (req, res, next) => {
//     next(new AppError(`Can't find ${req.originalUrl} on this server!`, 404));
//   });

module.exports = app;

型

server.js

const app = require('./app');
const dotenv = require('dotenv');

dotenv.config({ path: './../config.env' });

const port = process.env.PORT;
const server = app.listen(port, () => {
    console.log(`App running on port ${port}...`);
  });

  process.on('unhandledRejection', err => {
    console.log('UNHANDLED REJECTION! 💥 Shutting down...');
    console.log(err.name, err.message);
    server.close(() => {
      process.exit(1);
    });
  });

型

docController.js

const axios = require('axios');
const FormData = require('form-data');
const dotenv = require('dotenv');

dotenv.config({ path: './../../../config.env' });
SOME CONST VARIABLES FROM dotenv

const fs = require('fs')

function findValueByKey(obj, targetKey) {
  SOME BORING CODE
}

exports.getAccessToken = async (req, res, next) => {
  SOME BORING CODE
}

FOLLOWED BY FEW EXPORTED FUNCTIONS

型

docRoutes.js

const express = require('express');
const docController = require('./../controllers/docController');

const router = express.Router();

router.get('/get',docController.getAccessToken);
router.post('/create',docController.getAccessToken,docController.createDoc);
router.post('/submit',docController.getAccessToken,docController.addTagsAndSend);
router.get('/preview',docController.getAccessToken,docController.previewDoc);

module.exports = router;

型
代码之前是可以工作的，但是现在它在app和routes之间的某个地方中断了。有经验的Node js的人可以找到这个问题吗？
