Node.js 搭建web服务器

服务端脚本

1. Nodejs搭建web服务器响应html

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

const ip = '172.16.0.130';
const port = 3000;

var f = function(req, res){
  var reqUrl = url.parse(req.url);
  console.log(reqUrl.pathname);
  res.writeHead(200, {'Content-Type':'text/html;charset=utf-8'});
  res.write('<h1>ok</h1>');
  res.end();

}

var serverMsg = function(){
  console.log('Server Start !');
}

http.createServer(f).listen(port, ip, serverMsg);

2. Node.js搭建web服务器响应html静态文件

app.js文件：

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

const ip = '172.16.0.130';
const port = 3000;

var f = function(req, res){
  var reqUrl = url.parse(req.url);
  console.log(reqUrl.pathname);

  switch (reqUrl.pathname) {
    case '' || '/' || 'index':
      fs.readFile('index.html', function(err, data){
        //console.log(data);
        //res.write(data.toString());

        if(err){
          console.log(err);
        }else{
          res.writeHead(200, {'Content-Type':'text/html;charset=utf-8'});
          res.write(data.toString());
          res.end();
        }
      });
      break;
    default:

  }


}

var serverMsg = function(){
  console.log('Server Start !');
}

http.createServer(f).listen(port, ip, serverMsg);

index.html 文件:

<h1>hello YF</h1>

3. 运行服务端Node.js脚本

node app.js
