node搭建后端程序

1.引入http模块

const http = require('http');

2.配置端口

const config = {

port: 8003

};

3.创建服务

const server = http.createServer(function (req, res) {

console.log(`[${new Date().toISOString()}] coming request - ${req.method} ${req.url}`);

4.响应

return res.end('hello,word!!!!!!!!!!!!');

});

5.监听服务

server.listen(config.port);

console.log(`服务器端口号 ${config.port}`);
