如何从客户端访问我发布的数据(NodeJs)

const http = require('http');
const url = require('url');
const mysql = require('mysql');

// 创建数据库连接
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'username',
  password: 'password',
  database: 'database_name'
});

// 连接数据库
connection.connect();

// 创建服务器
const server = http.createServer((request, response) => {
  // 解析请求的URL和HTTP方法
  const { pathname, query } = url.parse(request.url, true);
  const method = request.method;

  // 处理GET请求
  if (method === 'GET') {
    // 根据请求的路径和参数执行相应的操作
    if (pathname === '/data') {
      // 查询数据库中的数据
      connection.query('SELECT * FROM table_name', (error, results) => {
        if (error) {
          response.writeHead(500, { 'Content-Type': 'text/plain' });
          response.end('Internal Server Error');
        } else {
          response.writeHead(200, { 'Content-Type': 'application/json' });
          response.end(JSON.stringify(results));
        }
      });
    } else {
      response.writeHead(404, { 'Content-Type': 'text/plain' });
      response.end('Not Found');
    }
  } else {
    response.writeHead(405, { 'Content-Type': 'text/plain' });
    response.end('Method Not Allowed');
  }
});

// 监听端口
server.listen(3000, () => {
  console.log('Server is running on port 3000');
});
