您可以使用
parse从方法URL模块在请求回调。
var http = require('http');var url = require('url');// Configure our HTTP server to respond with Hello World to all requests.var server = http.createServer(function (request, response) { var queryData = url.parse(request.url, true).query; response.writeHead(200, {"Content-Type": "text/plain"}); if (queryData.name) { // user told us their name in the GET request, ex: http://host:8000/?name=Tom response.end('Hello ' + queryData.name + 'n'); } else { response.end("Hello Worldn"); }});// Listen on port 8000, IP defaults to 127.0.0.1server.listen(8000);我建议您阅读HTTP模块文档，以了解
createServer回调函数。您还应该看看http://howtonode.org/之类的网站，并检查Express框架以更快地开始使用Node。
