Node.js灵活的路由

[code]var http = require('http');
var url = require('url');
function start(route) {
 var onRequest = function (request, response) {
 var pathname = url.parse(request.url).pathname;
 console.log("Request for " + pathname);
 route(pathname);
 response.writeHead(200, { "Content-Type" : "text/plain"});
 response.write("Hello Zhang Shan");
 response.end();
 }
 http.createServer(onRequest).listen(8888);
 console.log('Server has started');
}
exports.start = start;

[code]var server = require('./server');
var router = require('./router');
server.start(router.route);
