router.get('/page') express 路由器不工作

Question

我正在尝试做一个简单的快速路由，我在前端使用 vanilla HTML。

index.js

const express    = require('express'),
      bodyParser = require('body-parser'),
      serverless = require('serverless-http'),
      app        = express(),
      nav        = require('./routes/nav'), // the router 
      PORT       = process.env.PORT || 8080;

/* Settings */

app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static('./public'));

/* APIS */
app.use('/.netlify/functions/api', nav); //Navigation API

module.exports = app;
module.exports.handler = serverless(app);

if(process.env.NODE_ENV === "development"){
  app.listen(PORT, () => {
    console.log(`Server is runing on PORT: ${PORT} ENV: ${process.env.NODE_ENV}`);
  });
}

nav.js

const express    = require('express');

const router     = express.Router();
const PATH       = "../../public/";

router.get('/', (req, res) => {
  res.render(`${PATH}index.html`)
});

router.get('/graph', (req, res) => {
  res.render(`${PATH}pages/graph.html`)
})


module.exports = router;

每次我尝试使用标签进行路由时，它都会告诉我“无法获取 /graph”

我的HTML导航

<ul class="navbar-nav mr-auto">
          <li class="nav-item"><a class="nav-link" href="/">Home</a></li>
          <li class="nav-item mr-auto"><a class="nav-link" href="/graph">Graph Algorithims</a></li>
          <li class="nav-item"><a class="nav-link" href="/sort">Sorting Algorithims</a></li>
</ul>

我认为问题可能出在本地服务器上，我尝试部署到 netlify 看它是否在那里工作，但出现了同样的问题。

阅读你的代码，我似乎看不出你在哪里将 router.js 文件“连接”到你的 index.js。

要解决此问题，请在 index.js 中添加以下内容：

const router = require('path/to/router.js');
app.use(router);

router.get('/page') express 路由器不工作

router.get('/page') express Router not working
