server.js

var http = require("http");var url = require("url");function start(route){//route.js 的route方法  //服務(wù)實(shí)現(xiàn)  function onRequest(request,response){    var pathname = url.parse(request.url.).pathname;    route(pathname); //        response.writeHead(200,{"Content-Type":"text/plain"});    response.write("只是一個練手罷了");    response.end();  }  //創(chuàng)建服務(wù)  http.createServer(onRequest).listen(8888);//端口號8888  console.log("服務(wù)啟動");//后臺輸出,表示服務(wù)啟動成功}exports.start = start; //將start方法暴露出去

========================================

route.js

function route(pathname){  console.log("請求路徑是：" + pathname); //后臺查看請求路勁  區(qū)分請求的地址}exports.route = route;

index.js

var server = require("./server");var router = require("./route");server.start(router.route);//傳遞給start的是router的route方法
