Question

我正在对应用程序进行一些重构，但我不明白为什么这种情况失败了。

index.js

const express = require('express');
const router = express.Router();
const models = require('../models');
const listRoute = require('./list');

router.use('/list', listRoute);

list.js

const express = require('express');
const router = express.Router();
const models = require('../models');

const sendListDataToView = (req, res, view) => {
  // get data from backend and pass to template
}

router.route('/list/show/:id')
  .get((req, res) => {
    sendListDataToView(req, res, 'view-list')
  })

router.route('/list/expand-records-forms/:id')
  .get((req, res) => {
    sendListDataToView(req, res, 'edit-list-records')
  })

module.exports = router;

尝试导航到/list/show/3会引发404错误。但是，如果我将这些路由和sendListDataToView的定义移至index.js，则页面加载正常。是因为有多个router.route吗？

Answer 1

我只是要抹掉原来的答案。

您需要创建该应用。

const express = require('express');
const app = express();
const models = require('../models');
const listRoute = require('./list');

app.use('/list', listRoute); // Using express now. 

app.listen(8080); // starts server

使用模块化路由会引发404错误
