如何在singup页面添加姓名字段？

<form>
  <label for="name">姓名：</label>
  <input type="text" id="name" name="name" required>
  <!-- 其他输入字段 -->
  <input type="submit" value="提交">
</form>

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

app.use(express.urlencoded({ extended: true }));

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

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

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/signup', { useNewUrlParser: true });

const userSchema = new mongoose.Schema({
  name: String,
  // 其他字段
});

const User = mongoose.model('User', userSchema);

app.post('/signup', (req, res) => {
  const name = req.body.name;
  const user = new User({ name });
  user.save()
    .then(() => {
      // 存储成功的处理逻辑
    })
    .catch((error) => {
      // 存储失败的处理逻辑
    });
});
