var http = require("http"); http.createServer(function(request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello World"); response.end(); }).listen(8888);
现在它看上去应该清晰了很多：我们向 createServer 函数传递了一个匿名函数。
用这样的代码也可以达到同样的目的：
var http = require("http"); function onRequest(request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write("Hello World"); response.end(); } http.createServer(onRequest).listen(8888);
