node.js 学习笔记三:路由url

一、修改server.js

var http = require("http");
var url = require("url"); //导入内置url模块

function start(route){
    function onRequest(request, response){
        var pathname = url.parse(request.url).pathname; //提取url
        console.log("Request received.");
        console.log("Request for " + pathname + " received.")
        route(pathname) //路由
        response.writeHead(200, {"Content-Type": "text/plain"});
        response.write("Hello,World,Node.js");
        response.end();
    }
    http.createServer(onRequest).listen(8888);
    console.log("Server has started.")
}

exports.start = start

二、增加router.js

内容如下，

function route(pathname){
    console.log("About to route a request for" + pathname);
}

exports.route = route

三、修改index.js

var server = require("./server")
var router = require("./router")
server.start(router.route)
