网络服务 http server|Nodejs专题系列-前端进阶之旅

# http服务端概览

# 创建server

几行代码搞定

var http = require('http');
var requestListener = function(req, res){
    res.end('ok');
};
var server = http.createServer(requestListener);
// var server = new http.Server(requestListener); 跟上面是等价的
server.listen(3000);

# 获取请求方信息

# HTTP版本、HTTP method、headers、url

var http = require('http');

var server = http.createServer(function(req, res){
    console.log('客户端请求url：' + req.url);
    console.log('http版本：' + req.httpVersion);
    console.log('http请求方法：' + req.method);

    res.end('ok');
});

server.listen(3000);

效果如下：

客户端请求url：/hello
http版本：1.1
http请求方法：GET
http headers：{"host":"127.0.0.1:3000","connection":"keep-alive","cache-control":"max-age=0","upgrade-insecure-requests":"1","user-agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36","accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8","accept-encoding":"gzip, deflate, sdch, br","accept-language":"zh-CN,zh;q=0.8,en;q=0.6,zh-TW;q=0.4"}
