Node入门之Hello World

var http = require('http');
http.createHttpServer(function(request, response) {
   response.writeHead(200, {'Content-Type':'text/plain'});
   response.write('Hello World!');
   response.end();
}).listen(8080);

保存为server.js

node server.js

访问http://localhost:8080就可以看到大大的Hello World了
