尝试从包含某些数据的ejs文件向express服务器发送post请求，但req.body返回未定义

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

const app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

const axios = require('axios');

axios.post('/your-endpoint', {
  data: 'your-data'
})
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

<form action="/your-endpoint" method="POST">
  <input type="text" name="data" value="your-data">
  <button type="submit">Submit</button>
</form>

app.post('/your-endpoint', (req, res) => {
  console.log(req.body); // 输出请求体数据
  res.send('POST request received');
});
