Nodejs-- web服务器

浏览数：22 / 时间：2015年06月09日

第一篇关于nodejs的东西，代码在此作为备份。

该代码目前未完成，是一个阻塞式的代码。

1.index.js

ar server=require(‘./server‘);
var route=require(‘./router‘);
var requestHandler=require(‘./requestHandlers‘);

<!-- 声明一个对象  -->
var handle={}
handle[‘/‘]=requestHandler.start;
handle[‘/start‘]=requestHandler.start;
handle[‘/upload‘]=requestHandler.upload;

server.start(route.route,handle);

2.server.js

var http=require(‘http‘);
var url=require(‘url‘);

function start(route,handle){
        function onRequest(request,response){
                var pathname=url.parse(request.url).pathname;
                console.log(‘received pathname:‘+pathname);

                route(handle,pathname);

                response.writeHead(200,{‘Content-Type‘:‘text/plain‘});
                response.write(‘hello world‘);
                response.end();
        }
        http.createServer(onRequest).listen(8888);
        console.log(‘server has started‘);

}

exports.start=start;

3.route.js

function route(handle,pathname){
        console.log(‘About to route a request for ‘+pathname);
        if(typeof handle[pathname] == ‘function‘){
                handle[pathname]();
        }else{
                console.log(‘No request handler found for:‘+pathname);
        }

}

exports.route=route;

4.requestHandlers.js

function start(){
        console.log(‘Request handler START was called‘);
        function sleep(millsec){
                var startTime=new Date().getTime();
                while(new Date().getTime()<startTime+millsec);
        }
        sleep(10000);
        return ‘Hello Start‘;
}

function upload(){
        console.log(‘Request handler UPLOAD was called‘);
        return ‘Hello Upload‘;
}

exports.start=start;
exports.upload=upload;
