获取EJS模板中的表单参数

<form action="/submit" method="post">
  <input type="text" name="username" placeholder="Username">
  <input type="password" name="password" placeholder="Password">
  <button type="submit">Submit</button>
</form>

const express = require('express');
const bodyParser = require('body-parser');
const app = express();

// 解析表单数据
app.use(bodyParser.urlencoded({ extended: false }));

// 处理表单提交
app.post('/submit', (req, res) => {
  const username = req.body.username;
  const password = req.body.password;
  // 其他处理逻辑...
});

app.get('/', (req, res) => {
  res.render('index.ejs', { username: req.query.username, password: req.query.password });
});

<p>Username: <%= username %></p>
<p>Password: <%= password %></p>
