访问nodejs和express js中字段集合的值

const express = require('express');
const app = express();

app.get('/users', (req, res) => {
  // 在这里访问字段集合的值
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

app.get('/users', (req, res) => {
  const id = req.query.id;
  const name = req.query.name;
  // 处理逻辑...
});

app.get('/users/:id', (req, res) => {
  const id = req.params.id;
  // 处理逻辑...
});

const bodyParser = require('body-parser');
app.use(bodyParser.json());

app.post('/users', (req, res) => {
  const name = req.body.name;
  const email = req.body.email;
  // 处理逻辑...
});
