If You Want to do it after response.endyou should use Socket.ioor Server Send Events.
如果你想在response.end你应该使用Socket.io或服务器发送事件之后再做。
If you want it before res.end, you would make your code look like:
如果你之前想要它res.end，你会让你的代码看起来像：
var http = require('http');
var data = "data to send to client";
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.write(data); // You Can Call Response.write Infinite Times BEFORE response.end
response.end("Hello World\n");
}).listen(8125);
