如何在MERN堆栈应用程序中发送多个数据？

import axios from 'axios';

const data = {
  data1: 'value1',
  data2: 'value2',
  // ...
};

axios.post('/api/data', data)
  .then(response => {
    // 请求成功处理
  })
  .catch(error => {
    // 请求失败处理
  });

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

app.use(bodyParser.json());

app.post('/api/data', (req, res) => {
  const { data1, data2 } = req.body;
  // 处理接收到的数据
  // ...
  res.send('数据已接收');
});

app.listen(3000, () => {
  console.log('服务器已启动');
});

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

const dataSchema = new mongoose.Schema({
  data1: String,
  data2: String,
  // ...
});

const Data = mongoose.model('Data', dataSchema);

app.post('/api/data', (req, res) => {
  const { data1, data2 } = req.body;
  const newData = new Data({ data1, data2 });
  newData.save()
    .then(() => {
      res.send('数据已保存');
    })
    .catch(error => {
      res.status(500).send('保存数据时出错');
    });
});
