express代码演示

var express = require("express");
var bodyParser = require('body-parser');
var app = express();
var urlencodedParser = bodyParser.urlencoded({extended:false});

app.get("/index",function(req,res){
    console.log(req.fresh);
    res.send("Hello world");
});


app.post("/abc",urlencodedParser,function(req,res){
    var response = {
        first_name:req.body.a,
        last_name:req.body.b
    };
    console.log(response);
    res.end(JSON.stringify(response));
});

var server = app.listen(8081,function(){
    var host = server.address().address;
    var port = server.address().port;

    console.log("应用实例,访问地址为 http://%s:%s",host,port);
});

express真不错
