You must connect 'url' module
您必须连接 'url' 模块
var http = require('http');
var url = require('url') ;
http.createServer(function (req, res) {
var hostname = req.headers.host; // hostname = 'localhost:8080'
var pathname = url.parse(req.url).pathname; // pathname = '/MyApp'
console.log('http://' + hostname + pathname);
res.writeHead(200);
res.end();
}).listen(8080);
UPD:
更新：
In Node.js v8 url module get new API for working with URLs. See documentation:
在 Node.js v8 url 模块中获取用于处理 URL 的新 API。请参阅文档：
Note: While the Legacy API has not been deprecated, it is maintained solely for backwards compatibility with existing applications. New application code should use the WHATWG API.
注意：虽然 Legacy API 没有被弃用，但它的维护只是为了与现有应用程序向后兼容。新的应用程序代码应该使用 WHATWG API。
