node.js 8080端口未监听

Question

I'm following the node.js tutorial in here,

http://net.tutsplus.com/tutorials/javascript-ajax/learning-serverside-javascript-with-node-js/

this is the code,

var sys = require("sys"),  
http = require("http");  

 http.createServer(function(request, response) {  
response.sendHeader(200, {"Content-Type": "text/html"});  
response.write("Hello World!");  
response.close();  
 }).listen(8080);  

 sys.puts("Server running at http://localhost:8080/");  

in here, it says run like this url,

server's ip:8080/

but if i do this,

it just shows, cannot connect to this url.

i opened 8080 port in the server.

===========================

I'm assuming something is screwed up with codeigniter url helper...

Answer 1

The tutorial may be using an incorrect or deprecated method. Replace

response.sendHeader(200, {"Content-Type": "text/html"}); 

with

response.writeHead(200, {"Content-Type": "text/html"}); 

and

response.close();

with

response.end();

Answer 2

I Agree with the answer of Third .... make those changes and if it is local use this URL

http://127.0.0.1:8080/

But

If you are running your server not on localmachine but on something like webserver(AWS) , You have to let the security of AWS firewall to allow the port to be public on the internet and also remember to use the AWS instance URL

http://AWSinstanceURL:portno/

Answer 3

Use this one

//Lets require/import the HTTP module
var http = require('http');

//Lets define a port we want to listen to
const PORT=8080; 

//We need a function which handles requests and send response
function handleRequest(request, response){
    response.end('It Works!! Path Hit: ' + request.url);
}

//Create a server
var server = http.createServer(handleRequest);

//Lets start our server
server.listen(PORT, function(){
    //Callback triggered when server is successfully listening. Hurray!
    console.log("Server listening on: http://localhost:%s", PORT);
});

Now open http://localhost:8080 and u will get your result.
