使用节点js和jquery将数据从服务器端传递到客户端

const http = require('http');

const server = http.createServer((req, res) => {
  // 处理客户端请求
});

server.listen(3000, 'localhost', () => {
  console.log('Server is running on http://localhost:3000');
});

const fs = require('fs');

const server = http.createServer((req, res) => {
  fs.readFile('data.json', 'utf8', (err, data) => {
    if (err) {
      res.statusCode = 500;
      res.end('Internal Server Error');
    } else {
      res.setHeader('Content-Type', 'application/json');
      res.end(data);
    }
  });
});

$.ajax({
  url: 'http://localhost:3000',
  method: 'GET',
  dataType: 'json',
  success: function(data) {
    // 处理从服务器接收到的数据
  },
  error: function(xhr, status, error) {
    // 处理错误
  }
});
