Express js 路由器不工作

Question

我在使用 express js Routes 时遇到了困难。我有一个用户路由文件，我在 app.js （主文件）中需要它。但它总是给出Cannot GET /auth/register。

我的用户路线如下：

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

router.get('register', (req, res, next) => {
    console.log('Hello');
    res.send('Register');
});
module.exports = router;

而我的app文件如下：

const express    = require('express');
const path       = require('path');
const bodyParser = require('body-parser');
const cors       = require('cors');
const passport   = require('passport');
const mongoose   = require('mongoose');

const app = express();

const config     = require('./config/app');
const userRoutes = require('./routes/users');

//connecting with mongo DB
mongoose.connect(config.database);

// On successful connection
mongoose.connection.on('connected', () => {
   console.log('Connected');
});

// On Error while connecting
mongoose.connection.on('error', (err) => {
    console.log(err);
});

// Port of express server
const PORT = config.port;

// Adding cors middleware
app.use(cors());

// Adding Body Parser Middle ware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

// Adding user Routes

app.use('/auth', userRoutes);

// Start the express server
app.listen(PORT, function(err) {
    if (err) throw err;
    console.log("Server is Running on port " + PORT);
});

您忘记了用户路径中的符号“/”。试试这个：

router.get('/register', (req, res) => {
  console.log('Hello');
  res.send('Register');
});
