NodeJs解析web一例

var http = require('http');
var fs = require('fs');
var url = require('url');

http.createServer(function (request,response){
    var pathname=url.parse(request.url).pathname;
    fs.readFile(pathname.substr(1),function(err,data){
        if (err) {
            response.writeHead(404,{'Content-Type':'text/html'});
        }
        else
        {
            response.writeHead(200,{'Content-Type':'text/html'});
            response.write(data.toString());
        }
        response.end();
    });
}).listen(8888);
console.info("服务器已启动");
